Hello, I'd appreciate your help in spotting the reason for the error and warning messages below.
library(nnet) set.seed(1) ysim <- gl(3, 100) y <- model.matrix(~ysim -1) X <- matrix( 3 * runif(length(ysim)), nrow = 300, ncol = 3) X_new <- matrix( 3 * runif(length(ysim)), nrow = 200, ncol = 3) fit <- multinom(y ~ X, trace = FALSE) pred <- predict(fit, X_new, type = "probs") Error in predict.multinom(fit, X_new, type = "probs") : NAs are not allowed in subscripted assignments In addition: Warning message: 'newdata' had 200 rows but variables found have 300 rows Thanks, Lars.
