this is a question for limma developers.
at every new fresh installation of BioC and limma i get this message
when i use 'duplicateCorrelation()':
"statmod package required but is not installed"
i just install 'statmod' and problem solved. this, however, triggers
questions from some of my students since they expect that BioC
dependencies within functions are automatically installed when the
desired package is installed for the first time.
i've observed within the limma source that the 'statmod' functionality
is used within other functions and in all cases this is dealt as in
'duplicateCorrelation()', where first it's checked whether the package
namespace can be loaded and the user is asked otherwise to install it:
if(!requireNamespace("statmod",quietly=TRUE)) stop("statmod package
required but is not installed")
and the 'statmod' package is listed in the 'Suggests:' field of the
just out of curiosity, is there a particular reason to import the
functionality of 'statmod' in this way? wouldn't be possible to do it
