lattice and histogram

There is no problem if, at given level of "F", "X" is a mixture of good values and "NA"s; it seems to do the right thing by simply ignoring the latter. It's the case of "data = empty set" that seems to cause the trouble.
This is definitely a bug, which should be fixed in the next release of lattice. For now, what I can suggest is to change a couple of lines in the histogram() function. Replace xlim.l <- min(xlim.l, tem$xlim[1]) xlim.u <- max(xlim.u, tem$xlim[2]) by xlim.l <- min(xlim.l, tem$xlim[1], na.rm = TRUE) xlim.u <- max(xlim.u, tem$xlim[2], na.rm = TRUE)
Thanks, I'll give it a try.
PS: variable names like F might cause problems, since a lot of the lattice code use F/T instead of FALSE/TRUE. Again, this should not be so, and will be fixed in the next release.
That hadn't occurred to me! (I was using A, B, C, ... as variable names because those are the letters identifying columns in the spreadsheet I imported the data from). But you're surely right: the user should not need to bear in mind a lot of reserved symbols which he should not use as variable names. Looking forward to the next release!
