Hi Kelly,
The function has a limitation that it cannot handle any column in your "x" that
is a categorical variable with more than 32 categories. One possibility is to
see if you can "bin" some of the categories into one to get below 32 categories.

I think Gabor's incantation qualifies as my desired alternative to

However, the objection you raise to the gsub(deparse()) solution is
easily overcome through the use of an appopriate regex: e.g.:

I should have added:
If the formula is just assigned to a name, quote() and
eval(parse(...)) are not needed:
fm1 <- y ~ x1 ## a formula
w <- gsub( "x1","log(x1)", deparse(fm1))
fm2 <- formula(w)

I am using the poLCA package to find latent classes in a dataset with binary
outcomes. Several hundreds of persons can engage hundreds of items. Assume
100 items being engaged by 500 persons, the resulting dataframe is as shown
below (5 persons).
item1 item2 item3 item4 item5 .
Hi!!
My question is related to Rcmdr. I have Mac OS and I use R since more or less
1 year, not as an expert but I really like it. Now I want to install the Rcmdr
package, I already downloaded it, but when I want to "charged" R tell me that
it needed the tcltk package, so I downloaded it too

and replace x1 with something else, say x1c, so the formula would become
m1 <- lm(y ~ x1c, data=dat)

thank you very much for your reply, Rui Barradas.

Hello,
Instead of 'sum' use 'mean'
ok <- apply(tbl, 2, function(x) mean(!is.na(x)) >= 0.5)
cor(tbl[, ok], use="pairwise.complete.obs")
Hope this helps,
