Presumably there is no reason to attempt plotting an empty column, so best
approach is probably to remove the columns that contain no values.
Try
> f.temp<-f[,-which(apply(f,2,function(x)all(is.na(x]
and then run your script for f.temp instead of the original f.
Also, you may find you h
Let's say your data.frame is called xx
Then try:
apply(xx,2, function(x) {min(na.omit(x))} )
Does it work ?

Hi all,
I have got a dataset like the following:
a b c
1 5
2
3 7
I am taking the minimum of each column and use it as the minimum of the
y-axis of my graphs. My scripts (simplified version) are like the following:
f<-array
f[1]=a
f[2]=b
f[3]=c
for i in 1:3
name=f[i]
ymin<-min(datas
