Tables in legend
Thanks Jim. That was the first thing I tried. I should have mentioned
that I was also trying to write the three columns of the legend using
three different colors. So I want the "blah" column to be black, second
column to be red and the third column to be blue.
I would appreciate if you can share any ideas on how to do this.

This will probably do what you need:
plot(1)
x <- 1:10 # numbers for the legend
blah <- LETTERS[1:5]
legendData <- character(5)
for (i in 1:5)
legendData[i] <- sprintf("Blah-%s %d %d", blah[i], x[2*i - 1],
x[2*i])
legend('topright', legend=legendData)

I need to create a legend for a simple scatter plot in the following format. This is Blah1 number1 number2 This is Blah2 number3 number4 . . . This is Blah6 number11 number12 I looked up these help pages and found the following solution. lStr<-c(Blah1, Blah2,....Blah6, number 1, number2, ...number12) legend(x="topright",lStr,ncol=3) So this creates the tabular format I am looking for. But the width of each column is matched to the width of the longest column. So the
legend
now looks like this: This is Blah1 number1 number2 This is Blah2 number3 number4 . . . This is Blah6 number11
number12
And thus, I have the legend occupying most part of the top half of my plot. I was wondering if there is any way to fit in the legend
compactly
or even better to format the width of columns 2 and 3 in the legend
and
remove the blank spaces between them. I have tried rounding off the number values to 3 digits with no luck. I hope this is not too ambitious to ask. Thanks in advance! Aparna
