Hi all,
Could anybody help me figure out how to write text on a boxplot. I have to
plot 9 boxplots side by side on a single graph. On the x-axis I write numeric
values with the 'names' argument but I'd like to add one label (character
value) in the middle of each box. I know how to use the text() function for
regular y~x plots but in this particular case, I'm kinda lost...
Here is my code:
# creating labels for x-axis labelling
lb <- c()
for( n in names(o) )
lb <- c(lb, paste("\n",n,"\n",o[[n]], sep=""))
boxplot(x[,-c(10,11)],
varwidth=TRUE,
col=c("#FF0000","#EE0000","#DD0000","#00FF00","#0000FF","#0000DD","#0000BB","#000099"),
col.lab="dark red",
col.axis="blue",
main="Boxplots for Polling results, 1868 clusters, 9604 simulated
requests",
names=lb,
xlab="RED BOXPLOTS: precision dependent - GREEN BOXPLOT: null radius -
BLUE BOXPLOTS: percent of exact radius",
ylab="P(ID) values")
Thanks for your help,
Fanch
