Hi guys,

I have to make control quality of methylation data by ChAMP bioconductor package.

After running the following commands

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

BiocManager::install("ChAMP")

I found the following error message:

trying URL 'https://bioconductor.org/packages/3.12/data/experiment/src/contrib/ChAMPdata_2.22.0.tar.gz'

Warning in download.packages(pkgs, destdir = tmpd, available = available,  :

I also tried to download the ChAMPdata dependency through the following command

BiocManager::install("ChAMPdata")

And I found the following error message:

Bioconductor version 3.12 (BiocManager 1.30.10), R 4.0.5 (2021-03-31)

Could someone help me in solving this problem with ChAMPdata?

I used R in a Unix server. The uname -a output is:
