Package list error in Rstudio

RStudio IDE
1

Everytime I start or restart RStudio, I seem to have an error when it looks at the list of packages.
This text will be hidden

Error in (function (..., row.names = NULL, check.rows = FALSE, check.names = TRUE,  : 
  arguments imply differing number of rows: 263, 262

This error shows up practically everytime I try install a package or look at the list of packages in the Rstudio "packages" frame. The only time I've been able to get rid of it is when I start with a fresh user library. This makes me suspect that there is some package that isn't being registered appropriately. I'm not even sure how to debug this.

I've no idea about the cause of the error, but in terms of debugging, I would go down the following route:

Run

.libPaths()

to see the different directories that R looks at.

Then I would gradually build the number of directories checked up by using the R_LIBS environment variable in the .Renviron file. For example,

  • Set R_LIBS=FIRST_DIR_LIBPATHS
  • Set R_LIBS=FIRST_DIR_LIBPATHS,SECOND_DIR

I was able to get a traceback on the error. And it looks like one of the packages that I have installed is missing a "Title" element. I'm not really sure how to adjudicate which!

I figured this out. Basically, one of my custom packages didn't have a Title field in it's desciption file. I fixed that and the error went away.
