I am attempting to download the "psych" package in R and/or RStudio specifically for the describe.by function. Every time I get this message at the end:
"Warning in install.packages :
installation of package ‘psych’ had non-zero exit status"
I have have attempted downloading other packages in order to successfully get "psych" but quickly realized that this is a common issue for a lot of Mac users. Does anyone know how to solve this issue or if there are any other packages that will allow me to use describe.by?
