The mentioned issue starts between R-devel r71964 and r73003 I cannot narrow this range as I do not have available other versions between this date range.

Maybe it is the issue of Windows, but I cannot see anything weird when copying e.g. from Excel to Notepad Cheers Petr> > > > On 8/16/2017 1:25 AM, PIKAL Petr wrote: > > Hi Duncan > > > > The simples spreadsheet is: > > > > Put a name in the cell, let say "a1" > > Put number e.g. 1 below "a1" > > Copy the number to enough rows > > Select this column and press ctrl-c > > > > result is > > > >> temp<- read.delim("clipboard") > >> str(temp) > > 'data.frame': 1513 obs. of 1 variable: > > $ a1: Factor w/ 2 levels "1","a1": 1 1 1 1 1 1 1 1 1 1 ... > >> which(temp$a1=="a1") > > [1] 1365 > > I tested it in vanilla R > > > >> sessionInfo() > > R Under development (unstable) (2017-07-31 r73003) > > Platform: x86_64-w64-mingw32/x64 (64-bit) > > Running under: Windows 10 x64 (build 14393) > > > > Matrix products: default > > > > locale: > > [1] LC_COLLATE=Czech_Czech Republic.1250 LC_CTYPE=Czech_Czech > Republic.1250 > > [3] LC_MONETARY=Czech_Czech Republic.1250 LC_NUMERIC=C > > [5] LC_TIME=Czech_Czech Republic.1250 > > > > attached base packages: > > [1] stats graphics grDevices utils datasets methods base > > > > loaded via a namespace (and not attached): > > [1] compiler_3.5.0 > > Excel 16 or 15 I am not sure. > > > > R-devel 2015 (69443) works as expected so it started a believe around May > or June this year, when I installed new R version. > > > > I hope it could help to trace the problem.
