Hi Jean,

We'll need some more information about what you did and how you went
about doing it.

Firstly, did you use the CRAN R installer or did you do something
"unofficial" like homebrew?

Second, can you launch R from the Terminal? [1] If so, it's likely a
GUI problem and not a problem with R itself.

Thirdly, don't panic. If you saved your scripts in a reasonable place
(e.g., anything under your home directory) the R installer shouldn't
have touched it.

Cheers,
Michael


[1] If you don't know how to do this, click the "Applications" stack
in your dock. Then utilities. Then Terminal. A window (likely white
with black font) will appear; type "R" (no quotes) into it and hit
enter.
