Running R- under R-Studio on a Mac, OS Catalina 10.15.7

Downloaded from CRAN the package "tictoc". It appears to have been installed correctly but on trying to run it (either within a script or from the console window), get the error message "Could not find function 'tic'.

I reverted to using R (rather than R-studio), downloaded and installed the same package, and it runs correctly from the R-console. So it doesn't appear that there is a download or Mac security.

Expected the function "tic" to run from the R-studio console and in the script (which runs)

    how are you trying to run it? did you load the package (eg with `library(tictoc)` and was there an error message then? – George Savva Mar 11 '23 at 19:38

    Without additional details this is just a duplicate of the [could not find function](https://stackoverflow.com/questions/7027288/error-could-not-find-function-in-r) function. It's usually caused from failure to load the package. There's nothing "special" about this particular package. Please show the exact input/output from your R console where you are trying to use the function. – MrFlick Mar 11 '23 at 21:41
  • Thanks for the comments. The tictoc package was in fact correctly downloaded but I need to check the box in the "Install" pulldown menu of R-studio. It runs as advertised (https://cran.r-project.org/web/packages/tictoc/tictoc.pdf) – Ned Pugh Mar 15 '23 at 19:14
