Regarding 1, both cat(x) and print(x) have worked for me,

Hope this helps.

I had the same problem and came to this solution:
- use pdf() to create a pdf file
- open PDF in Freehand,
during open replace fonts: ZapfDingsbat for Zapf Dingsbat
- save as PDF or EPS and import this into word - bingo
The pdf files created by pdf() seem less than perfect - on my system
R and S-PLUS handle terms very differently.
If this were a formula, terms would dispatch to term.formula, so
presumably it is not. Do you need an as.formula() call?

I did not know about stepsize being an issue. I had thought that
problems with convergence in this case were due to bad approximations of

The simplest way is to define the method correctly, as print.myclass(x,
myarg, ...). That message is about the code, not the documentation, but
you will get a different one if the code and documentation disagree.

A common approach for getting data into R from Excel is to
save the spreadsheet as a CSV file and then read it into R
using read.csv. CRAN contains references to other means of
directly linking Excel and R. You may find the CSV approach
good enough.
