I'm not understanding why I'm unable to install the R package gisfin in github... 

library("devtools")
install_github("ropengov/gisfin")

  • Posting the output of `devtools::has_devel()` might shed more light on the problem. It *Checks if you have a development environment installed.* – R.S. Oct 21 '16 at 18:27
  • Thanks @R.S. I've added that info into my question. – Phil Oct 21 '16 at 18:52
  • So gcc is present. check this - http://stackoverflow.com/questions/35914339/error-could-not-find-build-tools-necessary-to-build It seems like user permission restriction causes this issue – R.S. Oct 21 '16 at 19:00
  • @R.S. That's correct - I installed in base R (I was originally trying in R Studio) and it worked fine. Thanks! – Phil Oct 21 '16 at 19:07
  • Great. I had recently grappled with similar situation on Linux, though I was trying to uninstall a package. BTW, you mean you installed from the administrative cmd prompt, right? – R.S. Oct 21 '16 at 19:11
  • You might also be having problems because Github's DNS is under attack right now, so name resolution problems might be preventing you from downloading. [You might try manually add the IP to a hosts file.](http://stackoverflow.com/a/40184256/4233593) – Jeff Puckett Oct 21 '16 at 19:39
