I tried to install custom R package 'sf' in the WRDS cloud via interactive R session, but failed. The instruction from WRDS is:
I followed the instructions and the package 'sf_0.9-6.tar.gz' is already in the '~/lib/R' directory:
When i tried to install the package in the interactive R session, i typed in the code :
install.packages("~/sf_0.9-6.tar.gz", lib = "~/lib/R")
I got the following error:
I don't understand why it is an invalid package, even though i've downloaded the package directly from CRAN. Besides, the package should work on the R 3.6.2.
Could anyone help? I would highly appreciated it!
