How about this? > x<-c(1:5,NA,NA,8:10) > y<-1:10 > plot(0,0,xlim=c(0,10), ylim=c(0,10),type="n",main="Dont show the bloody 0 > values!!") > lines(x~y, col="blue", lwd=2, subset = !is.na(x))
NAs let you do lots of useful manipulations in R.

Consider the following x<-c(1:5,0,0,8:10) y<-1:10 plot(0,0,xlim=c(0,10), ylim=c(0,10),type="n",main="Dont show the bloody 0 values!!") lines(x~y, col="blue", lwd=2,) My data is missing the 6th and 7th values and they come in as NA's so i change them to 0s but then the plot has these ugly lines that dive toward the x axis then back up. I would do bar plots but i need to show multiple sets of data on the same and side by side bars doesnt do it for me. So i need a line graph that starts and stops where 0s or missing values exist. Thoughts?
