Thanks again for your help. I did indeed solve the problem by plotting the initial graph as type='n', then adding my subset of points using 'points'.

Cheers,

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.
