Error: [Server error: (500) Internal Server Error] RockServerException, Error while evaluating 'base::source('.variable-cols.R')' -> Error : package ‘readr’ was installed before R 4.0.0: please re-install it
I have tried uninstalling and re-installing the readr package several times, tried updating the entire package set for R, tried re-starting the R server from Opal. I get the same error. The read package otherwise works fine:
> x<-read.csv("readr_test_csv.csv")
Warning message:
In read.table(file = file, header = header, sep = sep, quote = quote, :
incomplete final line found by readTableHeader on 'readr_test_csv.csv'
> colnames(x)
[1] "Field.1" "Field.2" "Field.3"
In terms of the readr package installation, here it is:
> pkgs <- opal.execute(o, "installed.packages()")
> pkgs['readr',]

This seems to limit our ability to call Opal objects/data for R analysis. Any ideas on why this might happen?
