Regardless of the particular reason why R-Studio cannot find the R compiler, the solution is simple. You simply need to get the compiler where it needs to be so that R-Studio can find it. This means that in this case there is no way of tweaking your script, R version, package, or anything else to fix the problem. Regardless of the precise cause, the problem is that R Studio cannot find the R compiler. The R compiler software has been deleted, renamed or otherwise altered.The R compiler software was not installed in the correct location on the computer.
However, there are three main reasons why the R console cannot find the compiler in the standard location. Using another operating system such as windows rather than Mac OS X would make R installation easier on your computer, but this issue can occur on a Windows operating system as well. The main place this error occurs is in R for Mac or Rstudio Mac, as the scanner and parts of the Mac OS X are not exactly built for R programming. Ultimately the reason for this error message is that R-Studio failed to find the R compiler software.
