[R] read.table with numeric row names

[jim holtman]

Try this:

> x <- read.table(text = "         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", header = TRUE, check.names = FALSE)
>
> x
    2.5 3.6 7.1 7.9
100 3.0 4.0   2   3
200 3.1 4.0   3   3
300 2.2 3.3   2   4
> names(x)
[1] "2.5" "3.6" "7.1" "7.9"
