[R] Row order in plot

[Sarah Goslee]

Then yes, you can do something like I originally suggested, though there
are other possible approaches.

Making up fake data rather than typing yours in:

> testdata <- as.data.frame(matrix(1:15, ncol=3))
> testdata <- cbind(c("D", "E", "A", "C", "B"), testdata)
> colnames(testdata) <- c("X", "c1", "c2", "c3")
> testdata$X <- as.character(testdata$X)
>  testdata
  X c1 c2 c3
1 D  1  6 11
2 E  2  7 12
3 A  3  8 13
4 C  4  9 14
5 B  5 10 15


> plot(1:nrow(testdata), testdata$c1, xaxt="n")
> axis(1, at=1:nrow(testdata), labels=testdata$X)

Gives what I think you want.
