Hi everyone, I am having an issue with PSMATCHING. I have tried psmatching versions 3.04 and 2. Ever time I run the program on SPSS version 23, put the variables in, and wait for the output, the processor will run and count cases up to the mid 100,000s, then get stuck and never produce an output. I have tried on both PC and Mac. I believe my R-plug-in is working because when I put in : Beging program R. x <- "R plug-in is working properly" x End program. I get no error messages. Thank you in advance...
