Hi all,
I am new to R, but with the help I have received thus,I have already been able
to work through a bunch of questions on my own in just a few days. I imagine
my questions are relatively simple, but here she goes.
1) I am using a package where one of the objects generated represents X/Y
coordinates for each observation. I have been able to plot my row names onto
the graph using text() (with the help of this list), but because it is entirely
possible for some rows to have the same X/Y coordinates, I need to separate the
data labels so that I can clearly see each.
I tried text(jitter(coordinates), labels = abbreviate(rownames(dataset),
minlength=3)), but it appears that jitter effect is the same for each x/y pair
and not unique to each row.
Hi Brock,
You have just found another use for the "spreadout" function in the
plotrix package:
plot(1:10,type="n")
labels<-c("one","two","three","four","five","six",
"seven","eight","nine","ten")
xpos<-c(2,2,4,4,6,6,8,8,9,9)
ypos<-c(2,2,4,4,6,6,8,8,9,9)
library(plotrix)
text(xpos,spreadout(ypos,0.3),labels)
Jim
