I try to install R-Studio - it goes round and round - it warns that it will reboot, but it doesn't.

In R I got the following log

> install.packages("inTrees")
Устанавливаю пакет в ‘C:/Users/S_V_A/Documents/R/win-library/4.0’
(потому что ‘lib’ не определено)

why install R-Studio ?

 
Aleksey Vyazmikin #:

In R, this is the log

try it

install.packages("inTrees", dependencies=TRUE, repos='http://cran.rstudio.com/')

And it's better to change the console output to English, then you can google problems normally

why install R-Studio ?

I guess you should have put a comma there. It was about the place where the package was installed.

Can you elaborate? Or an example. Which values, which FF?
