Hello, When we start Calc it does not go to the home screen but instead it says "R executable directory must contain valid R executable file". When we put the directory in line it does not accept it. What are we doing wrong? Calc Version: 2.1 R Version: 3.4.3 Thanks |

Did you put a valid directory? Note it should be the full path of where r.exe is located. Also, make sure you install R in a folder without space. E.g. C:\opt\R\R.3.3.1\bin Thank you Mino |

Hi Folks, this is the case that happens nowadays almost every time with Calc and R because files and folders under C:\Program files are Read-only by default (by Windows). In this case, R (and RStudio) puts all packages under C:\Users\USERNAME... and Calc can not find them. Calc assumes that R packages are under Library folder in the same path where R is installed. There are multiple solutions to fix this, until Calc programmer fixes this. Solution 1) Right click C:\Program files\R and take a tag out from Read-only. Then reinstall all packages in R/Rstudio so that the target in the Library folder under that path. Solution 2) Remove Read-only tag as above. Copy all installed R packages from C:\Users\USERNAME... to C:\Program files\R\R_VERSION\Library\ and start using Calc Solution 3) Reinstall R under C:\Users\Public.. and reinstall all R packages. This is not a Read-only folder by default. I strongly wish that this issue can be solved in Calc without these tricks by its users. Cheers |
