Example: xxx <- data.frame(x=1:26,y=letters) xxx$x[c(2,4,6,8)] <- NA xxx$y[c(1,3,5,7)] <- NA
yyy <- edit(yyy) The missing values in xxx$y appear as blanks in the spreadsheet window that appears, whereas the missing values in the numeric column "x" appear as "NA" (as I would expect). Is this a bug or a feature? cheers, Rolf Turner P.S. > sessionInfo() R version 2.12.0 (2010-10-15) Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit) locale: [1] en_NZ.UTF-8/en_NZ.UTF-8/C/C/en_NZ.UTF-8/en_NZ.UTF-8 attached base packages: [1] datasets utils stats graphics grDevices methods base other attached packages: [1] misc_0.0-13 gtools_2.6.2 spatstat_1.20-5 deldir_0.0-12 [5] mgcv_1.6-2 fortunes_1.4-0 MASS_7.3-8 loaded via a namespace (and not attached): [1] grid_2.12.0 lattice_0.19-13 Matrix_0.999375-44 nlme_3.1-97 [5] tools_2.12.0 ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
