Hello list,
I've been working on this problem for a while and I haven't been able
to come up with a solution.
I have a couple of functions that plot a bunch of data, then a single
point on top of it. What I want is to be able to change the plot of
the point without replotting all the data. Consider the following
example:
x = rnorm(100,1,0.5)
y = rnorm(100,1,0.5)
plot(x,y,pch=16)
points(x[35],y[35],pch=19,col=6,cex=3)
What I want to be able to do is to change the purple point to a
different value without replotting everything.
I know this seems like an odd suggestion, but it comes up a lot with
the work I'm doing. I've prepared a package on CRAN called
ResearchMethods for a course I'm working on, and there are several
functions in there who's GUIs could work better if I could figure this
out.
If anyone has any ideas, or needs some further explanation, feel free
to contact me.
Thanks a lot,
Sam Stewart
