[Rd] incorrect report (was write.table in R 2.0.0) (PR#7312)
Note this is nothing to do with write.table, as> data.frame(x=c(1,2), x=c(1,2))x x.1 1 1 1 2 2 2 which write.table faithfully reports. This change *is* in the NEWS file o data.frame(check.names = TRUE) (the default) enforces unique names, as S does. However, there are several bugs I wish to report in a.buness@dkfz.de, who has wasted our time with this report by 0) Not reading the help pages for write.table and data.frame 1) Not reading the section BUGS in the FAQ 2) Not reading the posting guide 3) Not reading the NEWS file 4) Using an incorrect subject line 5) Not actually saying what the bug is supposed to be.

This has nothing to do with write.table. The column names in x are
"x" and "x.1".
This is documented in the NEWS file:
o data.frame(check.names = TRUE) (the default) enforces unique
names, as S does.
