i have been trying to execute r script of variant call analysis in a snakemake
rule VCA analysis:
shell: "Rscript vca.R"
but when i run it, but it gives the error
Installing package into ‘/usr/local/lib/R/site-library’ (as ‘lib’ is unspecified) Warning in install.packages("BiocManager") : 'lib = "/usr/local/lib/R/site-library"' is not writable Error in install.packages("BiocManager") : unable to install packages Execution halted
why is it showing this kind of error ??
