problem with mixomics, packages in R

Question

[stefania.morelli92]

Hi, I have to install the R package "mixomics" I use this command to download the package:

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

BiocManager::install("mixOmics")

But this is the result:

byte-compile and prepare package for lazy loading help * installing help indices building package indices ** testing if installed package can be loaded from temporary location Error: package or namespace load failed for 'igraph' in dyn.load(file, DLLpath = DLLpath, ...): unable to load shared object '/home/student4/R/x86_64-pc-linux-gnu-library/4.1/00LOCK-igraph/00new/ig raph/libs/igraph.so': libgfortran.so.4: cannot open shared object file: No such file or directory Error: loading failed Execution halted ERROR: loading failed

I tried to download the package ('igraph') but i have the same problem! How can I resolve this problem? my R version is 4.1.2. TKS Stefania

You're missing a fortran compiler. sudo apt-get update followed by sudo apt-get install build-essential should include GCC, which should resolve your problem.
