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.

Subject: [R] Dont show zero values in line graph
Hey everyone,
Im getting better at plotting my data but cant for the life of me figure
out how to show a line graph with missing data that doesnt continue the line
down to zero then back up to the remaining values.
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?
