Installing Issue

[daisukeadachi]

Hi Paul,

I tried devtools::install_github("paulgp/bartik-weight/R-code/pkg") but had the following error. Could you help me figure out what is wrong?

Error: Failed to install 'bartik.weight' from GitHub:
  (converted from warning) installation of package ‘/var/folders/sq/8c5rcbd1197g_169brd3c6p80000gn/T//RtmpbG1f5I/file7342583b840/bartik.weight_0.1.0.tar.gz’ had non-zero exit status

My environment is as follows. Thank you!
