ggraph unable to collate and parse R files for package ‘ggraph’

[Corina-Mihaela-Motofeanu]

Hey, I am trying to install ggraph for clusterProfiler but came across this issue:

installing to /home/rstudio/R/x86_64-pc-linux-gnu-library/4.0/00LOCK-ggraph/00new/ggraph/libs
** R
Error in parse(outFile) :

ERROR: unable to collate and parse R files for package ‘ggraph’

• removing ‘/home/rstudio/R/x86_64-pc-linux-gnu-library/4.0/ggraph’

The downloaded source packages are in
‘/tmp/RtmpPPHGBN/downloaded_packages’
Warning message:
In install.packages(...) :

Anyone knows what is wrong?

We are in the same boat: I already encountered and reported this issue last Thursday, see issue #364. The developers of ggraph inadvertently used the native pipe in their new release, which is a language feature of R that was introduced in R 4.1. Thus, the current version of ggraph (which was released one week ago) does not compile with R versions prior to R 4.1, such as yours (you used 4.0).

In this comment, the maintainer of ggraph acknowledged that a patch release for ggraph is necessary to fix that. They are currently discussing on whether to adjust the R-version dependency or to revert the use of the inadvertently used language feature. As there have already been others who voted for reverting the change, I hope that they will revert it and fix this problem soon, but I am still waiting for a response of the maintainer in issue #364. Hopefully, they can fix this soon...

I hope that helps you on the long run. For a fast work-around, I (as a user of ggraph, not a contributor) suggest to either upgrade to a more recent R version (if possible on the machine you use) or install a previous version of ggraph (which might also not be the desired solution as you might miss current fixes in older package versions).
