plot(1:4,1:4,xlim=c(5,0),ylim=c(5,0))
shows axis labels as:
| | | | | |
0
rather than
| | | | | |
5 4 3 2 1 0
as I believe it used to do in some earlier version.
Thank you for R.

Dear Sirs, Thank you very much for your replies. If I may, and assuming this makes sense, I would like to suggest as a low-priority wish-list item for a future version that perhaps the plot function could take an additional optional argument (e.g. reverse, which can have values "x", "y" or "xy") which would make the plot function do the calculations suggested by Dr Dalgaard below to allow easy plotting with reversed axis values, and even prehaps issue a warning message for xlim=c(5:2) to make it clear that this is not supposed to work that way? Just some thoughts. Thank you again!
