I'am a beginner at doing R program and not an English speaker.
So the problem is that every single time I put
, the same error comes out.
Warning: Rtool is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding :
Even though I download R, Rstudio and Java again and try it at new environment, the error is same.
I also tried with a manager mode.
I have no idea on earth what I'm doing wrong.
Would you please let me know the point of my mistake? Thank you.
