[R] distance between legend title and legend box
Hi, I've looked at the parameters available for the legend function and cannot find a way to change the distance between the top of the box surrounding a legend and the legend's title. I have a math expression that raises the height of my title. If you don't mind the non-sensical title I give to the legend for this plot (Figure 3.20 in R Graphics): with(iris, plot(Sepal.Length, Sepal.Width, pch=as.numeric(Species), cex=1.2)) legend(6.5, 4.2, c(setosa, versicolor, virginica), cex=1, pch=1:3, title=expression(kg/km^2)) The result depends on the device, but I think any device will show the box needs to be raised a bit (in quartz, the top of the box passes in the middle of the 2, in pdf it is acceptable, but just (the top of the box lightly touches the top of the 2).

Re: [R] distance between legend title and legend box
I don't know if there is a nice, easy way of doing this, but this method will work: with(iris, plot(Sepal.Length, Sepal.Width, pch=as.numeric(Species), cex=1.2)) lg-legend(6.5, 4.2, c(setosa, versicolor, virginica), cex=1, pch=1:3, title=expression(kg/km^2), bty=n) x1 - lg$rect$left y1 - lg$rect$top - lg$rect$h x2 - x1 + lg$rect$w y2 - lg$rect$top + .1 # change the .1 to get more or less space rect(x1,y1,x2,y2) On 26/10/06, Denis Chabot [EMAIL PROTECTED] wrote: Hi, I've looked at the parameters available for the legend function and cannot find a way to change the distance between the top of the box surrounding a legend and the legend's title.

Looking at the source for legend(), it only expects the title to be zero or 1 lines high (i.e., either no title or a title that is one line of normal text high). It needs a rewrite to allow for the exact height of the title text.
