Hello,

I am having difficulty installing the most recent compatible version of the
?polycor" package (0.7-8), for R 3.2.1 on my Mac. Here is the package
source page: https://cran.r-project.org/src/contrib/Archive/polycor/
<https://cran.r-project.org/src/contrib/Archive/polycor/>.

This version of R is necessary for the R Essentials for the IBM Statistical
Package for Social Sciences (SPSS) extension. I found this thread on the problem
(http://r.789695.n4.nabble.com/Installing-polycor-package-td4726101.html
<http://r.789695.n4.nabble.com/Installing-polycor-package-td4726101.html>)
but it does not offer much help as my SPSS version will not recognize the most
recent versions of R.

The polycor package is not available in the repository of R 3.2.1. Here is the
code I tried to install the package from the archive and the errors I received:

> install.packages("/polycor_0.7-8.tar", repos=NULL,
type="source")
Warning: invalid package ?/polycor_0.7-8.tar?
Error: ERROR: no packages specified
Warning message:
In install.packages("/polycor_0.7-8.tar", repos = NULL, type =
"source") :
  installation of package ?/polycor_0.7-8.tar? had non-zero exit
status
>
install.packages("https://cran.r-project.org/src/contrib/Archive/polycor/polycor_0.7-8.tar.gz",
repos=NULL, type="source")
Error in download.file(p, destfile, method, mode = "wb", ...) :
  unsupported URL scheme

Any ideas for other alternatives would be greatly appreciated. Thank you for
your time!

Best,
Evguenia
