Dear all
My gRbase package imports the packages from Bioconductor: graph, RBGL and
Rgraphviz
If these packages are not installed, then gRbase can not be installed. The
error message is:
ERROR: dependency ‘graph’ is not available for package ‘gRbase’
If I, prior to installation, run setRepositories and highlight 'BioC software',
then gRbase installs as it should, because the graph package from Bioconductor
is installed along with it. However, this extra step is an obstacle to many
users of the package which means that either people do not use the package or
people ask questions about this issue on stack overflow, R-help, by email to me
etc. It is not a problem to get the package on CRAN because, I guess, the CRAN
check machines already have the three bioconductor packages installed.
Therefore, I wonder if there is a way of specifying, in the DESCRIPTION file or
elsewhere, that these packages should be installed automatically from
bioconductor.
An alternative would be if one could force the error message
ERROR: dependency ‘graph’ is not available for package ‘gRbase’
to be accompanied by a message about what the user then should do.
Any good suggestions? Thanks in advance.
Best regards
Søren
