In my personal experience, this error message is most often associated with typos.
Note your error message says "extrTrees", there should be an a
between the r and the T.
You are right there was a typo but when I tried with the correct spelling I got the same error.
Are you sure that is the correct spelling? this command works normally on R 3.5.2 (RStudio Cloud)
install.packages("extraTrees")
100% sure I even copied your line and re executed the command.
Have you checked that RStudio has internet access? is your internet connection behind a proxy server or firewall? that is usually the case when you are at work or school.
Unfortunately it is not the case; I am at home and the internet connection is perfect.
Try specifying the repository, and post the exact error message that you are getting.
install.packages("extraTrees", repos='http://cran.rstudio.com/')
Well this time the message was different:, here it is:
Warning in install.packages :
unable to access index for repository https://cloud.r-project.org/src/contrib:
'wget' call had nonzero exit status

Error in library(extraTrees) : there is no package called ‘extraTrees’
This really looks like a connectivity issue, are you completely sure there there is no firewall or antivirus blocking internet access for RStudio?
Yes I am sure that there is not.
