Hi, I can not install rTANDEM and it is needed in the Mass spectrometry and proteomics data analysis (http://bioconductor.org/packages/devel/workflows/html/proteomics.html).

I run the command:

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")

BiocManager::install("rTANDEM")

"Warning message: package ‘rTANDEM’ is not available for this version of R"

library("rTANDEM")

Error in library("rTANDEM") : there is no package called ‘rTANDEM’

Any help or at least clarification would be appreciated. Thanks, Gilad

As the message says, rTANDEM isn't available. Indeed, it currently fails building and is marked as deprecated (which means it will be removed from Bioconductor at the next release). In other words, you won't be able to run X!Tandem from within R.
