Hi!
I am VERY new to coding and need to install the r package "polr." I have been using r studio and an r markdown file. Every time try to install install.packages('polr',repos='R/polr.R')
I get these error messages
Warning in install.packages :
unable to access index for repository R/polr.R/src/contrib:
cannot open URL 'R/polr.R/src/contrib/PACKAGES'
Warning in install.packages :
package ‘polr’ is not available (for R version 3.5.3)
Warning in install.packages :
unable to access index for repository R/polr.R/bin/macosx/el-capitan/contrib/3.5:
cannot open URL 'R/polr.R/bin/macosx/el-capitan/contrib/3.5/PACKAGES'
Please send help.
