Gavin,
I ran into the same cryptic "invalid subscript type 'closure'" message in
a slightly less complicated scenario, and wanted to post the cause in
my case (the root cause is probably the same either way).
Similarly to your case, I was subsetting a data frame. I had a list
of variable names

The usual way to call
Dear List,
I am writing a formula method for a function in a package I maintain. I
want the method to return a data.frame that potentially only contains
some of the variables in 'data', as specified by the formula.
The problem I am having is in writing the function and wrapping it
around model.fr

Thanks Gabor,
Yes, I know that works, but I want the function coca.formula to accept a
formula like this y2 ~ y1, with both y1 and y2 bei
It can handle data frames like this:
model.frame(y1)
or
model.frame(~., y1)

Hi I'm having a problem with model.frame, encapsulated in this example:
y1 <- matrix(c(3,1,0,1,0,1,1,0,0,0,1,0,0,0,1,1,0,1,1,1),
nrow = 5, byrow = TRUE)
y1 <- as.data.frame(y1)
rownames(y1) <- paste("site", 1:5, sep = "")
colnames(y1) <- paste("spp", 1:4, sep = "")
y1
model.frame(~ y
16 matches
