Okay. I think I understand now. You would just like nothing to be plotted for the points below a certain threshold but there will still be that space indexing where the point would've gone. I hope I have this right.
So what you could do to fix that is to make a new matrix (still including all the data) and then make values above a certain threshold NA. #Make up some data > a=seq(1,100,by=1) > b=runif(100,0,0.5) #Make a matrix > matrix=cbind(a,b) #Make values above a threshold = NA > newmatrix=matrix > newmatrix[,2][which(newmatrix[,2]<0.1)]<-NA #Plot values > plot(newmatrix[,2]~newmatrix[,1], ylim=c(0,1), las=1, ylab='Explan', > xlab='Window') Okay. You just solved it. I'll still post this if you would like to use it.
