Hello. I have a (most probably stupid) question about one of the nnet error messages that I can not understand : Error in matrix(NA, length(keep), nout, dimnames = list(rn, dimnames(object$fitted)[[2]])) : length of dimnames[1] not equal to array extent it happens in predict.nnet(). Here is my code : iue.nnet <- nnet.formula(FAMILY2 ~ FLUX.0+FLUX.1+FLUX.2+FLUX.3 .... FLUX.556+FLUX.557+FLUX.558+FLUX.559+FLUX.560+FLUX.561, data = spectra.log.family2.tiny, na.action = na.omit, size=2, MaxNWts=32000 ); iue.nnet.predict <- predict.nnet(iue.nnet, spectra.log.family2.tiny, type="class") Thanks a lot... -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
