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.
