Installation

Production Version

install.packages(c("MALDIquant","MALDIquantForeign"),type="source")
install.packages("MGMS2")
library("MGMS2")

or

R -e 'install.packages("MGMS2")'

Development Version

install.packages(c("MALDIquant","MALDIquantForeign"),type="source")
devtools::install_github("unreno/MGMS2")
library("MGMS2")

or

R -e 'devtools::install_github("unreno/MGMS2")'

Usage

library('MGMS2')

Removal

remove.packages("MGMS2")

Developer

Initial Creation

install.packages(c('devtools','roxygen2'))
library('devtools')
library('roxygen2')
create('MGMS2')

The “create()” function fails with “Error: Directory ‘MGMS2’ does not exist.” after it creates DESCRIPTION and NAMESPACE files and an empty R/ dir. Kinda pointless. Could’ve just used a simple template for this. Is that what its supposed to do?

Creation / Updation / Posting

Create/Edit .R files in R/ folder with properly formated documentation above functions.

Then update NAMESPACE and man/ from within R …

library('devtools')
document()

Or from the bash command line …

R -e 'library(devtools);document()'

Install from the bash command line …

R -e 'library(devtools);document();setwd("..");install("MGMS2",upgrade=FALSE)'

Or from R with some manual checking with sample data …

remove.packages("MGMS2")
library('devtools')
document()

setwd('..')
install('MGMS2',upgrade=FALSE)
library('MGMS2')
lsf.str("package:MGMS2")
"MGMS2" %in% rownames(installed.packages())



spectra.processed.A <- process_monospectra(
    file=system.file("extdata", "listA.txt", package="MGMS2"),
    mass.range=c(1000,2200))
spectra.processed.B <- process_monospectra(
    file=system.file("extdata", "listB.txt", package="MGMS2"),
    mass.range=c(1000,2200))
spectra.processed.C <- process_monospectra(
    file=system.file("extdata", "listC.txt", package="MGMS2"),
    mass.range=c(1000,2200))

spectra.mono.summary.A <- summarize_monospectra(
    processed.obj=spectra.processed.A,
    species='A', directory=tempdir())
spectra.mono.summary.B <- summarize_monospectra(
    processed.obj=spectra.processed.B,
    species='B', directory=tempdir())
spectra.mono.summary.C <- summarize_monospectra(
    processed.obj=spectra.processed.C,
    species='C', directory=tempdir())

mono.info=gather_summary(c(spectra.mono.summary.A, spectra.mono.summary.B, spectra.mono.summary.C))

gather_summary_file(directory=tempdir())

mixture.ratio <- list()
mixture.ratio['A']=1
mixture.ratio['B']=0.5
mixture.ratio['C']=0

sim.template <- create_insilico_mixture_template(mono.info)

insilico.spectrum <- simulate_poly_spectra(sim.template, mixture.ratio)

insilico.spectrums <- simulate_many_poly_spectra(mono.info, mixture.ratio=mixture.ratio, nsim=10 )
