I suggest you download the .zip file of this repository from the green "Clone or Download" icon.

Installing with the following, changing the path as appropriate.

devtools::install_local(path = "~/Downloads/ggbiplot-master.zip")

Hi!

I managed to progress through a lengthy solution, which finally made a successful 'ggbiplot' installation:

1. I was struggling to install the 'devtools' package on my RStudio. I realised that it was due to the problem with the 'curl' package dependencies. I followed the solution posted by user3327344 here:

https://stackoverflow.com/questions/42115972/configuration-failed-because-libcurl-was-not-found/45649051#45649051

2. After this, I restarted my R session and installed the libraries (curl and then devtools).

3. I was still having problems to install the ggbiplot package from the install_github command. But the above answer by @trickytank solved this!

Thanks!
