I understand now. Thanks for the explanation.
I would have figured it out myself had I paid attention to the fact that the
error message reports "row names" rather than "column names", or had the
error message actually contained the conflicting names (either "0" or "1") or
the full set of read names.
We can fairly easily do something along those lines: I've added code to
R-devel to do
library(MASS)
row.names(hills)[35] <- "Lomonds"
Error in `row.names<-.data.frame`(`*tmp*`, value = c("Greenmantle", "Carnethy",
:
duplicate 'row.names' are not allowed
In addition: Warning message:
non-unique value when setting 'row.names': ‘Lomonds’
