What about just setting them to missing and plotting?

md<- yourdata
md[md==0]<- NA

My other idea depending how you want the plot to look would be to try something 
where 0 values get a blank colour or null plotting value



Or the OP is going to just ignore such data and want to plot na.omit(md) after you had set all 0 to NA.

Hi,

i have some data in a matrix.  It has zero values scattered throughout, at 
random.

I'd like to create a line plot, with a line for each row, that *excludes* the 
zero or NA values.

The data looks like this (toy example)

10 12 21 0 23 0 43 0 NA 41
0 0 0 34 35 0 35 0 44 0
NA NA NA 3 2 5 0 3 2
etc...

Suggestions on an easy way to do this?

Thanks!
