# Calc Problem in 001-init.R

Asked by wexxo on 2023-05-02

Hi,

after some time, I needed Calc to run again. While the scripts seem to be working in R Studio, as soon as I press the "play" button in calculations to load them into Calc, I receive the following error message indicating that my CRAN mirror is not defined(?):

*Error in 'R Scripts - Processing chain' 
 2023-05-02 18:58:46     step : 1-init.R
INFO: Processing chain started 
2023-05-02 18:58:46     step : -
ERROR: Error in contrib.url(repos, "source"): trying to use CRAN without setting a mirror
 
Error in dbDisconnect(connection) : 
  could not find function "dbDisconnect"
Calls: source ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>
Execution halted*


I have tried to alter the Rprofile and Rprofile.site files in ..opt\R\R-4.1.1\library\base\R and ..opt\R\R-4.1.1\etc, respectively. Unfortunately to no avail.

Any pointing in the right direction would be highly appreciated!

Thanks in advance!
Alex

Hi OF Team,

I updated R in C:\opt\R\R-4.3.0 (from ver. 4.1.1). Now the scripts are being processed fine in Calc, so the problem is solved!

Thanks a lot for the hint and support!!

Best regards,
Alex
