[R] problems with read.table()

[Ott Toomet]

Hi,

I have lately migrated to R 1.4.0.

trying to read a table into R with read.delim, I hot the following error:

> tab20 <- read.delim("tab20.and")
Error in "row.names<-.data.frame"(*tmp*, value = row.names) :
	duplicate row.names are not allowed

The beginning of the file looks like (there are TAB-s between columns, both
in the header and in the datalines):

t	prod
7.00000	0.0113800
9.00000	0.0113800

The read.delim() works fine as long I have only 51 lines of data in addition
to the header, but if there are 52 or more lines, the first column is read
in as the row.names and because some t-values coincide, it gives the error.

I have noticed problems with read.table here in the list before, but I could
not figure out what is the corresponding patch, and how to find and install
it.

I have RH 7.1 linux and

platform i686-pc-linux-gnu
arch     i686
os       linux-gnu
system   i686, linux-gnu
status
major    1
minor    4.0
year     2001

Thanks in advance,

Ott Toomet
