Thanks for the suggestion, Tad, but that's not quite it. That is still taking a
subset of the whole data set, so I am losing some of the x("Window") values. I
need to be able to retain all of the x values (column a in your example), but
not plot any points above. Maybe I need to construct a blank x-y plot first
with the needed range of x values, then use "points" to plot my data values?
Not sure how exactly to do that...

Subject: Re: [R] help filtering points from a scatterplot
I believe this is what you want to do, though it may need tweaking.
#Make up some data
> a=seq(1,100,by=1)
> b=runif(100,0,0.5)
#Make a matrix
> matrix=cbind(a,b)
#Subset the matrix based upon values of interest
> subsetmatrix=matrix[which(b<0.1),]
#Plot values
>
> plot(subsetmatrix[,2]~subsetmatrix[,1],ylim=c(0,1),las=1,ylab='Explan',xlab='Window')
Hope this helps.
