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(dataset$f[i])
plot(x,y,ylim=c(ymin,100))
The script stops at b, because the min function returns inf value. What can
I do to overcome it?
Many thanks,
Chris
