I am getting this error when trying to biocLite() the latest version:

 

Error in dyn.load(file, DLLpath = DLLpath, ...) :

ERROR: lazy loading failed for package 'ChAMP'
* removing '/home/****/R/x86_64-pc-linux-gnu-library/3.4/ChAMP'

I know that there is a limit of the number of libraries used at any point, but I have nothing else loaded into the session apart from base packages.

running the following checks:

named list()

Hello:

The reason is R does not allow users to load more than 100 DLL. But some large packages like ChAMP would load many dependence, and these dependencies would also load many other packages.

I am now fixing this issue, but it's really challenging because I need to decrease some relying packages maybe. A quick solution for you is that you can reset your Renviron file and add one line: R_MAX_NUM_DLLS=512, then this error should be no more.

The Renviron file should be at /usr/local/lib64/R/3.4.4/lib64/R/etc (on my computer), or you can created .Renviron file in your home folder to fix this issue.
