environment question: changing variables from a formula through model.frame?
...using it.
It involves changing variables that are found through using model.frame on a
formula inside a function.
I wonder if it's a "bug" or a "feature". And in either case, how it might
be managed.
Here is a simple example:
# let's say we have an x and y variables:
temp_x <- rep(1,5)
temp_y <- c(1:5)
# we now create a function that will take a formula of y~x and will (try and
*fail* to) change "y" (only) inside the environment of this function:
foo1 <- function(formu)
{
print("Before changing the 'y' variable in the formula")

multinom crashes (when I do something stupid) (PR#8358)
...ccurred in
Rgui.exe." This has happened on both my laptop and desktop (it took me a while
to see my mistake!). It can be easily reproduced with made-up data, e.g.
library(nnet)
set.seed(1) # not really needed, but definitely crashes for this!
temp_g <- as.factor(rep("level1",10))
temp_x <- rnorm(10)
multinom(temp_g ~ temp_x)
Cheers,
Rob.
