read.table with numeric row names
I have a text file like this
2.5 3.6 7.1 7.9
100 3 4 2 3
200 3.1 4 3 3
300 2.2 3.3 2 4
I used "r <- read.table("a.txt", header=T)"
The row names becomes X2.5, X3.6... What I need is the row names are
numeric, so I can use the row names as numbers on x-axis for plotting. e.g.
"plot(colMeans(r)~names(r))",
