...ector. However, when I enter n95trt <- length(byyr$cnd95[byyr$cnd95=="tr"]) n95trt the result is 68! Any ideas why this is happening, and how I can fix the miscount? (That column also contains 69 entries of "c", and (relevantly?) two NA's.) Thanks for any help. Dave Parkhurst

....25 inches numeric(0) Is my call to identify correct? The help page for indentify (from ?identify) doesn't give any examples, so I don't know what the "x" should be. I right click right on top of one of the points, then left click and select stop. Thanks for any help. Dave Parkhurst

...the manual, and the help system as best I can, and I don't see how to change the font size. Can it be changed from within a session, or will I have to ask the folks who installed the program on the server I use in classes to set it (assuming that can be done)? Thanks for any help.

Greetings: I would like to make a table with descriptive statistics for a data.frame. I guess the question is how can I put together, in a table, the results from, say: apply(df, 2, mean, na.rm =T) apply(df, 2, median, na.rm =T) .......

...variables, in about 5% of rows. I would like to have all rows included in the analysis, to the extent possible. (That seems to be possible in rpart, for example.)

...al axis. I've looked in all the manuals, but didn't find a way to do this. I can copy the data to a spreadsheet, make the conversion there, and then move the data to R, but that's a nuisance. I'd appreciate learning whether there is a way to do this all within R. Thanks. Dave Parkhurst

At work I have no permission to install R. So, would anyone know whether it is possible to create a CD with a running R-installation for a windows(XP) pc? And of course, how to? Thank you for your help, Hans van Walen
