Hello,

I think you are trying to combine too many things into one.

for(i in 1:100){
>    points(cor(v$logA[v$id>i], v$logB[v$id>i], use="complete.obs"), i))
> }
> (i created a plot object already)


For points() you need to have x and y, but you are giving the output of
cor()

This will plot your data and print the correlations on the plot (lathough
maybe not in the best place):

for(i in 1:100){
   points(v$logA[v$id>i], v$logB[v$id>i], pch=i)
   text(0, i, cor(v$logA[v$id>i], v$logB[v$id>i], use="complete.obs"))
}

 Hopefully that gives you an idea of how to get the output you actually
want.

Sarah
