[R] Matching with the function "matchCases"

[langensk@fas.harvard.edu]

Dear all,

I would like to perform a simple matching. The few cases should be matched 
with one or several controls that are similar to the cases with respect to one 
variable. I have tried to use the function "matchCases" without success; my 
program does not recognize this function. The function matchCases does not 
seem to be downloadable from CRAN, and my version has been resently updated. I 
would be very happy if someone knows the answer to my problem.

Thanks in advance,
Sophie
