I am getting an error message when I try to run MARK models with groups defined and the latest versions? of R (2.9.0) and RMark (1.8.9). The models run fine on computers with an earlier version of R (2.8.1) installed. I've gotten the same error message in the "Burnham" and "Multistrata" modeling frameworks. The error is:
Error in if (inherits(X[[j]], "data.frame") && ncol(xj) > 1L) X[[j]] <- as.matrix(X[[j]]) :
missing value where TRUE/FALSE needed
Should I just downgrade my version of R for now?
Thanks,
Jeff
