Hello,
I am trying to use R for propensity score matching in SPSS. I have version 21
of SPSS and I downloaded R 2.14.2 as directed as well as the R Essentials
plug-in. I have run a test for R and it appears to be running correctly. I
then downloaded psmatching3 and have tried to use the PS matching dialog in
SPSS. However, I continue to run into problems as SPSS reports that there is
no 'cem' file. I have tried to download cem separately from your website (both
the new and the older version) and to install it either in R or as an extension
in SPSS but I receive the following errors:
IN R:
utils:::menuInstallLocal()
Warning in install.packages(choose.files("", filters = Filters[c("zip", :
'lib = "C:/Program Files/R/R-2.14.2/library"' is not writable
Error in install.packages(choose.files("", filters = Filters[c("zip", :
unable to create '~/R/library"' > $HOME/.Renviron'
In addition: Warning message:
In dir.create(userdir, recursive = TRUE) :
cannot create dir 'C:\Users\Kimberley\Documents\R\library"' > $HOME', reason
'Invalid argument'
In SPSS:

I would definitely appreciate any suggestions or feedback!
Thanks!
