Works for me in R 2.3.1 (patched) Are you mistaking the printed representation of your data.frame for the real thing. E.g.: # dummy data dat <- as.data.frame(matrix(rnorm(100)+ 0.000000000000012, ncol = 10)) # not that reading/writing has anything to do with this, but just to # prove it write.table(dat, file = "~/tmp/temp.csv", sep = ",") dat <- read.table("~/tmp/temp.csv", sep = ",", header = TRUE) dat options(digits = 14) dat or print(dat, digits = 14) G Ps. Wasn't sure about the etiquette of replying to R-bugs in recipients, so deleted it in case this caused further work for the maintainer(s) of the bug repository. Sorry if this isn't desirable. -- %~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~% * Note new Address, Telephone & Fax numbers from 6th April 2006 * %~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~% Gavin Simpson ECRC & ENSIS [t] +44 (0)20 7679 0522 UCL Department of Geography [f] +44 (0)20 7679 0565 Pearson Building [e] gavin.simpsonATNOSPAMucl.ac.uk Gower Street [w] http://www.ucl.ac.uk/~ucfagls/cv/ London, UK.
