I have tried installing package car on my Macbook and have followed the threads on here and spent hours online looking for solutions. I have tried manual install in R, auto install on R-studio, tried changing the mirror site, installed many extras as many of the threads talked about. (fortran, ggplot, ggplot2, data.table... ) Prof spent a while with me... no avail. and still I get this error:
Warning in install.packages : installation of package ‘rio’ had non-zero exit status
Warning in strptime(xx, f <- "%Y-%m-%d %H:%M:%OS", tz = tz) :
