I am trying to install and load TCGAbiolinks. It was working before, but probably due to some package that was installed, it suddenly stopped working. This happened before, but unninstalling and reinstalling R and RStudio solved the problem. But not now...

I already tried unninstalling R and RStudio twice, to no avail. The last time I installed ROpen 3.4 and RStudio-1.1.359.

The solution was to install an older version of `gridExtra`. Version 2.2.1 worked

Source: A: package or namespace load failed for TCGAbiolinks

gridExtra changed some of their function names which TCGAbiolinks imported;  Until TCGAbiolinks updates their NAMESPACE and code this ERROR will occur.  The Bioconductor team is in the process of reaching out to TCGAbiolinks to make the appropriate changes.  For now installing the older version of gridExtra will also work.
