Hi,
I have sets of three points provided by subjects that I want to graph
as lines over a specific range, but the subjects were split into two
groups and provided different points. The subjects provided a y-value
for the given x-value, for example:
Subject: 1 2 3 4 ... 127
"1" NA 3 2 NA ...
"2" 4 NA NA 4
"3" 6 6.5 6 5.5
"4" 7 NA NA 7
"5" NA 8 7.5 NA
Using matplot() or xyplot() I can easily get R to plot the lines for
subjects 1 and 4, but R wont draw lines connecting the points for
subjects 2 and 3 since there are missing values. I want R to just
connect the points for B and C as if the missing values don't matter
and make it look as if each subject provided 5 points. What is the
best way to do this?
- Chris
