Does this do what you want:
mydata <-read.table('mydata.txt',header=TRUE, row.names=1)
see ?read.table

Subject: [R] row.name in data.frame
Hi Group,
I have a table with column names and row names.
Species A B C D E F G
Human 1 2 3 4 1 0 3
Rat 0 2 3 3 2 1 2
I read this tab delim. text file into R like the
following:
> mydata <-read.table('mydata.txt',header=TRUE)
> mydata
Species A B C D
1 Human 1 2 3 2
2 Rat 0 2 5 2
3 Cat 9 2 4 1
Why am I getting 1,2,3 row names even after declaring
heder = TRUE. I tried declaring row.names = NULL,
however it is not accepting it and expects a vector
with some names. I wanted Human, Rat and Cat as my row
names. I wanted my data frame look like:
Species A B C D
Human 1 2 3 2
Rat 0 2 5 2
Cat 9 2 4 1
I apologise for asking a lame question and this
question might have been posted several times. I could
not find an answer.
Thanks
P
