# Error in 'R Scripts - Processing chain'   null

Asked by wexxo on 2017-08-03

Dear OF Community,

maybe someone can help me with the error message above. I just updated R and now, when I am asking Calc to write the results of the calculations (work in R without problems) into the database, I receive this error during step 1 'R Script Processing chain'. I have two different surveys, but the same error occurs in both of them. Any ideas?

Thank you!

Dear Alex,

make sure the R executable path is correct in the system page (It must ends with bin).

Also, make sure the required libraries are installed in the R library path.

Please let me know if this helps.

Thanks
Mino

Thanks for the quick answer Mino,

unfortunately, I couldn't solve the problem following your suggestions.
Concerning the libraries, I assume this refers to the packages (*RPostreSQL* and *sqldf*), which I installed (and updated).

The fact that I previously updated R to v.3.4 can't be the problem can it?

Hi Alex,

i haven't tested Calc with R 3.4, however it shouldn't be the problem.

Can you send me the log files?

Thanks,

Mino

Hi Mino,

having installed the new R version in another folder other than c:\opt seems to have caused the issue.
I believe, R should always be installed in the c:\opt folder!

Thank you so much for your help! It is greatly appreciated!

Alex
