Hi R people!


I am printing a table of percentages (P) and their 95% confidence
interval half-widths (CI).

I would like to 

(i) create a character string of P and CI that has the plus/minus
character to the left of CI, then

(ii) use write.csv to save that file with the P, CI and the special
plus/minus character.

I poured over the r-help archives and did not find advice on this. That
advice could be there, but I did not see it! 

Thank you!
