How do you enable scp in libcurl when using with R?

Question

I am trying to use scp from within RStudio to directly access a remote log file. I can use scp from the command line and it works great. But within RStudio I get the following error:

Protocol "scp" not supported or disabled in libcurl

How can I enable scp?

I am using the curl and RCurl libraries with RStudio

I spent several hours to resolve this. This link solved my issue.

Reinstall curl following this link - https://askubuntu.com/questions/1128780/how-to-build-the-latest-curl-from-sources-to-allow-downloading-files-via-sftp

Then, reinstall RCurl:

install.packages("RCurl",type="source")
