I previously turned on packrat() in RStudio. I now wish to completely remove and disable it (i.e. revert to the state prior to installing packrat). I tried to find an option in Rstudio to disable it but could find anything. I therefore uninstalled R and RStudio by (on OSX 10.9.5) dragging the icons for R and RStudio from the applications folder to the trash. However, upon reinstallation of R (version 3.2.3), the R console displayed the following message and a pop-up prompted me to select a CRAN mirror:
Packrat is not installed in the local library -- attempting to bootstrap an installation... No source tarball of packrat available locally --- Please select a CRAN mirror for use in this session ---
So, I found in Library a folder named 'packrat.' After deleting this, I now receive the following upon starting R:
Error in file(filename, "r", encoding = encoding) :
cannot open the connection
In addition: Warning message:
In file(filename, "r", encoding = encoding) : cannot open file 'packrat/init.R': No such file or directory
This is the same error as found in: Trouble with packrat corrupting R functioning yet no .Rprofile or .Rhistory files are found when I search in Finder and I do not know which working directory to search in manually. Can someone advise on how to implement the solution linked above?
The issue was indeed that .Rprofile wanted to initialize packrat() on starting R. To fix this, use the below.
