Re: [R] Reversing axis label order
Dear Steve, I'm not sure I properly understood the question. Try x<- aggregate_1986 # just a shortcut n<- dim(x)[[1]] matplot(x[n:1,1], x[n:1,2:3], type="l", col=2:3) is that what you needed?

[R] Reversing axis label order
Dear R Users, I am executing the following command to produce a line graph: matplot(aggregate_1986[,1], aggregate_1986[,2:3], type="l", col=2:3) On the x-axis I have values of Latitude (in column 1) ranging from -60 to +80 (left to right on the x-axis). However, I wish to have these values shown in reverse on the x-axis, going from +80 to -60 (ie. North to South in terms of Latitude). I have tried doing this by altering the command as follows: matplot(-aggregate_1986[,1], aggregate_1986[,2:3], type="l", col=2:3) ...but this produces the inverse sign of the latitude values along the axis - ie. it goes from -80 to +60. How do I reverse the display of the axis labels correctly and of course, maintain the associated data values correctly?
