Fix Github issue #26 related to extremely long warning/error messages
save_results_filename
added to
runSimulation()
saving details to allow asynchronous
(though unchecked) file storage to the same results directory (suggested
by Jan Göttmann)
ECR()
gain a complement
logical to
indicate whether parameter was outside advertised interval (complement
of coverage). Useful when CIs are used as formal hypothesis tests (e.g.,
bootstrap CI tests for power)
runSimulation(..., extra_options)
changed to
control
instead to control less commonly used
flags
createDesign()
gains a fractional
argument to support design input structures from the FrF2
package for fractional factorial designs. Useful when detecting
main/low-dimensional interaction effects across a large number of factor
variables (suggested by Achim Zeileis). Example added to the wiki to
demonstrate its use
When summarise()
function not supplied the
Design
input is now appended to the results
object when using SimExtract(res, what = 'results'
). Only
supported when the results
object is a
matrix
-like structure
RAM
element added to resulting objects to indicate
the amount of RAM used during each evaluation. This is particularly
useful when using runSimulation(..., store_results = TRUE)
to inspect how much RAM is being being consumed (otherwise,
runSimulation(..., save_results = TRUE)
should be used if
RAM storage is suspected to be an issue)
resummarise()
and
aggregate_simulation()
now better support the internally
stored results terms when using
store_results = TRUE
runSimulation(..., save = TRUE)
changed to
save = replications > 10
to only write temporary files
when the replications are larger (less hard-drive strain when initially
testing simulation experiment with very small replications)
hexsticker added to make SimDesign
part of the
cool-kids club
filename
and save_results_dirname
extractors added to SimExtract()
PBA()
function added for probabilistic bisection
algorithm, with associated print()
and plot()
S3 methods
debug
gains '-'
structure to allow
debugging on specific rows of the design
input. For
instance, if the simulation ran successfully until row 10, and unknown
errors terminated the simulation, then using
runSimulation(..., debug = 'error-10')
will initiate the
debugger on the first instance for the 10th row conditions in the
supplied design
object
Progress reporting now includes abbreviated condition names and values in the console per condition
New function nc()
to be used in situation where
uniquely naming a vector or list according to the object names is useful
(cf. x <- c(A,B,C)
, which typically returns an unnamed
vector, to x <- nc(A,B,C)
, in which
names(x)
is "A" "B" "C"
). This is mainly
useful in the Analyse()
step where objects must be named
uniquely in order to track the results in
Summarise()
Added Bradley1978()
for test of Bradley’s (1978)
robustness interval for empirical detection/coverage rate
statistics
runSimulation(..., Generate)
can now be specified as
a named list of functions similar to Analyse()
, however
only the first valid data generation function will be used as the
constructor of the simulated data (see the new GenerateIf()
function to control the flow of these generation steps). This list input
should really only be used when the population generation functions are
differ widely depending on the condition
under
investigation
SimFunctions()
adds a few new inputs for saving one
or more files (save_structure
), defining one or more
generate function (nGenerate
), whether to include an extra
file for user-defined objects and functions (extra_file
),
and whether a basic knitr::spin()
header should be included
when saving the files (spin_header
)
Support the future
package by using
runSimulation(..., parallel = 'future')
to replace the
built-in parallel processing inputs. Using the future
package approach makes several arguments to runSimulation()
unnecessary as these can be specified when defining
future::plan()
(e.g., cl
, MPI
,
etc)
When using the future
approach the
progressr
package is used. Allows the progress bar to be
started via progressr::with_progress()
and modified by the
front-end user (see ?runSimulatino
for an example using
progressr::handler()
)
extra_options
gains support for
.options.mpi
to control the MPI properties documented in
doMPI
quite()
now removes the sunk connection temp file to
save storage issues (e.g., when distributing on Slurm)Attach()
gains an omit
argument to omit
specific elements from being attached to the working environment
(default still attaches all objects supplied)Using a list definition for Analyse
input now
executes all functions by default regardless of errors thrown. Error
messages and seeds remain captured in the output, however are labelled
according to the number of errors that were observed (e.g.,
SimExtra(result, what = 'errors')
may return column with
"ERROR: 2 INDEPENDENT ERRORS THROWN: ..."
). Previous early
termination default can be reset by passing
extra_options = list(try_all_analyse = FALSE)
to
runSimulation()
. Special thanks to Mark Lai for bringing
this to my attention on Issue #20
Added beep
argument to runSimulation()
to play a beep message via the beepr
Added RSE()
function to compute the relative
behaviour of the average standard error to the standard deviation of a
set of parameter estimates across the replications
(RSE = E(par_SEs) / SD(par_ests)
)
Bugfix for new list input for analysis functions when error raised (reported by Mark Lai)
SimExtract()
gains a fuzzy
argument to
allow fuzzy matching of error and warning messages. This helps collapse
very similar errors messages in the recorded tables, thereby improving
how to discern any pattern in the errors/warnings (e.g., Messages such
as “ERROR: system is computationally singular: reciprocal condition
number = 9.63735e-18” and “ERROR: system is computationally
singular: reciprocal condition number = 6.74615e-17” are
effectively the same, and so their number of recorded occurrences should
be collapsed)
Added AnalyseIf()
function to allow specific
analysis function to be included explicitly. Useful when the defined
analysis function is not compatible with a row-condition in the
Design
object. Only relevant when the analyse
argument was defined as a named list of functions
The analyse
argument to runSimulation()
now accepts a named list
of functions rather than a single
analysis function. This allows the user to separate the independent
analyses into distinct functional blocks rather than having all analyses
within the same function, and potentially allows for better modularity.
The debug
argument now also accepts the names of these
respective list elements to debug these function definitions
quickly
SimFunctions()
gains an nAnalyses
argument to specify how many analysis functions should be templated
(default is 1, retaining the previous package defaults)
Various performance improvements to reduce execution overhead
(e.g., REPLICATION
ID now moved to an
extra_option
as this was identified as a
bottleneck)
Meta-statistical functions now support a
fun(list, matrix)
input form to compute element-wise
summaries that return a matrix
structure
Summarise()
can now return list
arguments that can later be extracted via
SimExtract(sim, what = 'summarise')
. Consequently, because
list outputs are now viable the purrr
package has been
added to the suggests
list
Prevent aggregate_simulations()
from overwriting
files and directories accidentally. As well, the auto-detection of
suitable .rds files has been removed as explicitly stating the
files/directories to be aggregated is less error prone
Removed plyr::rbind.fill
in favour of
dplyr::bind_row()
, which removed plyr
as a
dependency
Attach()
now accepts multiple list-like objects as
inputs
Added SimCheck()
for checking the state of a
long-running simulation via inspecting the main temp file
sessioninfo
package used in placed of the
traditional sessionInfo()
Print number of cores when parallel processing is in use
A number of arguments from runSimulation()
moved
into extra_options
list argument to simplify
documentation
Parallel processing now uses FORK instead of PSOCK when on Unix machines by default
More natural use of RPushbullet
by changing the
notification
input into one that accepts a character vector
(“none”, “condition”, “complete”) to send pbPost()
call.
Also more informative in the default messages sent
Added “Empirical Supremum Rejection Sampling” method to
rejectionSampling()
to find better constant
M (useful when there are local minimums in the
f(x)/g(x)
ratio)
rejectionSampling()
made more general, with
additional examples provided in the help files
Bootstrap CI estimates moved into runSimulation()
,
deprecating the less optimal SimBoot()
runSimulation(..., save=TRUE)
now default to always
store meta-information about the simulation state
Added renv
to the suggests lists since it’s useful
to hard-store package versions used in simulations
data.frame
objects largely replaced with
tibble
data frames instead as they render better for larger
simulations
Support for rbind()
and cbind()
on
final simulation results to add additional condition/meta-summary
information
Use createDesign()
instead of
expand.grid()
in code, which provides more structured
information and flexibility
Added SimExtract()
to extract important but silent
information
Added stop_on_fatal
logical argument to more
aggressively terminate the simulation rather than do things more
gracefully
