PS and, BTW,
Not sure why you are doing it, but you can do it like this:
m = matrix(c(1,3,4,2,2,5,1,6,3), nrow =3)
[,1] [,2] [,3]
[1,]121
[2,]326
[3,]453
t(m)[ , ncol(m):1]
[,1] [,2] [,3]
[1,]431
[2,]522
[3,]361
I hope
I belive that
apply(t(mat),2,rev)
[,1] [,2] [,3]
[1,]163
[2,]225
[3,]134
will do what you want. I'll leave it up to you to decide
whether it's straightforward.

One approach:
Read in and plot background image (possibly using EBImage package or other).
Use the updateusr function from the TeachingDemos package to set the user
coordinates to match your image.
Add points using points or symbols function.
Hope this helps,
