Hi,
I have some code that looks like:
dftc <- df[sets$tcset,]
pt <- numeric(nrow(dftc))
sub <- 1:nrow(dftc)
for (i in 1:nrow(dftc)) {
n <- nnet( fmla, data=dftc, weights=wts, subset=sub[-i], size=4,
decay=0.01)
pt[i] <- predict( n, dftc[ i, ], type='class' )
}
However running this give me the error:
Error in eval(expr, envir, enclos) : Object "i" not found
I have noted this problem in some other instances. For example if I
define a function
f <- function( dat, sets ) {
# use sets
}
I sometimes get an error similar to that above.
Does anybody know why this would happen?
