[R] Specifying relative position of text in a plot
What is the simplest way to specify the location of text in a scatter plot (created using the plot function) in relative terms rather than specific x-y coordinates? For example, rather than putting text at (300,49) on a plot, how do I put it 1/10 of the way over from the y axis and 1/2 of the way up from the x axis? Thanks.

Re: [R] Specifying relative position of text in a plot
See ?par, entry usr. Either set a new coordinate system and use it, or convert 1/10 to user coordinates. In R-devel (2.7.0 to be) this is easier: text(grconvertX(0.1,npc), grconvertY(0.5, npc), some text) cnvrt.coords() in package TeachingDemos does something similar (although it doesn't use the standard R names for coordinate systems, and there are more than 5).

Re: [R] Specifying relative position of text in a plot
I tested the main set of examples from cnvrt.coords using the new grconvert functions and they worked perfectly. I have already noted in the help page for cnvrt.coords (for the next version coming out soon) that people should start using grconvertX and grconvertY when they become available. Are there any more of the utilities in TeachingDemos that will be need to be depricated with the release of version 2.7? (I read through the current NEWS file, but are there any more planned?). -- Gregory (Greg) L.

Re: [R] Specifying relative position of text in a plot
To left justify the text rather than center, use the adj argument, this is easier and probably more reliable than trying to adjust the x coordinate manually. -- Gregory (Greg) L.

Re: [R] Specifying relative position of text in a plot
Here is one way. ... usr - par(usr) # get user coordinates par(usr = c(0, 1, 0, 1)) # new relative user coordinates text(0.1, 0.5, Some text, adj = 0) # if that's what you want par(usr = usr) # restore original user coordinates ... If you were going to be doing this a lot, you could write a simple wrapper function to text(...) to incorporate this change to relative coordinates and back again.
