I want to write some text in a corner of my plot. Is it possible to get the xlim and ylim of an open window? Or is there anything similar like legend(x="bottomright", inset=0.01,legend=...) for text(x=1,y=2, "test") Thomas

You can get the x and y position of any place of an open graphic device with the mouse cursor, using the function locator(), and even assing this values to an object, as in: xy<-locator() You will have a list with x and y positions. Then you can use: text(xy$x,xy$y,...) See ?locator. HTH, Fernando Mayer.

?par, look at "usr" (which is how legend does it) On Thu, 9 Feb 2006, Thomas Steiner wrote:> I want to write some text in a corner of my plot. > Is it possible to get the xlim and ylim of an open window? > Or is there anything similar like > legend(x="bottomright", inset=0.01,legend=...) > for > text(x=1,y=2, "test")-- Brian D.

par('usr') will give you the coordinates of the corners of the current
plot.
If you want to go a little beyond this (more like your legend example) by
specifying that you want your text to be some distance from the bottom and left
of the plot and have the distance not affected by the scale of the data then you
might want to look at the cnvrt.coords function in the TeachingDemos package.

Subject: [R] putting text in the corner
I want to write some text in a corner of my plot.
Is it possible to get the xlim and ylim of an open window?
Or is there anything similar like
legend(x="bottomright", inset=0.01,legend=...)
for
text(x=1,y=2, "test")
Thomas
