With a recent R 2.4 I notice the following: df <- data.frame(x=1:2) > row.names(df) [1] "1" "2" > rownames(df) [1] 1 2
This seems related to recent changes in the internal storage format of
the row names data for data frames.
The man page for rownames says:
For a data frame, 'rownames' and 'colnames' are equivalent to
'row.names' and 'names' respectively.
A number of Bioconductor packages seem to be relying on this.
