Two-line title in R legend
The top line is not outside the box in this example, but the bottom text line is too close to the bottom. You can turn off drawing the box in legend(). Store the return value of legend() which indicates where the box would have been drawn and use rect() to add it after increasing the dimension you need. In the example I lowered the bottom of the box by .1:
plot(c(0:10), rnorm(11), ylim=c(-3, 3)) pos <- legend(.5, 3, "Top of title\nBottom of title", pch=1,
+ bty="n")
pos
$rect $rect$w [1] 2.558594 $rect$h [1] 0.6723839 $rect$left [1] 0.5 $rect$top [1] 3 $text $text$x [1] 1.0625 $text$y [1] 2.578779
xleft <- pos$rect[["left"]] ytop <- pos$rect[["top"]] ybottom <- ytop - pos$rect[["h"]] xright <- xleft + pos$rect[["w"]] rect(xleft, ybottom-.1, xright, ytop)

To try to break the title in two lines, I am using legend (title="Top of Title\nbottom of title", etc. ) R prints the title as two lines, but the top line is outside the legend box. How can I trick the R legend function to make the legend box taller so that it contains the top line? Thanks, Gabriel
