Hello all,
Say I would like to change the outcome in a formula to a variable not part of
the original dataset. This works just fine:
res <- lm(mpg ~ wt + cyl, data=mtcars)
res
y <- rnorm(nobs(x))
update(x, formula = y ~ .)
But not when doing so within a function:
rm(y)
f <- function(x) {
y <- rnorm(nobs(x))
update(x, formula = y ~ .)
}
f(res)
Is there a way to make this work? Using y <<- ... inside the function works,
but I would like to avoid such a heavy-handed approach.
Best,
Wolfgang
