Dear All,
The textplot() function in the wordcloud package seem to do a good job with
generating non-overlapping labels on a scatter plot.
But it throws "warnings" when I try to use the pos= parameter to position the
text labels relative to a given x-y point.
Here is a simple example:
x<-runif(100)
y<-runif(100)
text1<- rep('LAB', 100)
plot(x,y)
textplot(x,y, text1, new=F, show.lines=F,
pos=4)
There were 50 or more warnings (use warnings() to see the first 50)
> warnings()
Warning messages:
1: In strwidth(words[i], cex = cex[i], ...) : "pos" is not a graphical parameter
2: In strheight(words[i], cex = cex[i], ...) : "pos" is not a graphical
parameter
How can I pass the pos=parameter to text() without generating the warnings?
I am doubly puzzled by the warnings because in the graph that results from the
foregoing code,
The labels are to the right of the points, as 'pos=4' requests.
Thanks!
