[R] Matching with the function "matchCases"
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
