Ted,

Yes, I did.

Yes, here was the misunderstanding.
Subset required a vector, and I gave it a scalar.
Prof. Ripley has already shown my mistake.

Dear r-help,
I have the following function defined:
cubic.distance<-function(x1,y1,z1,x2,y2,z2) {
max(c(abs(x1-x2),abs(y1-y2),abs(z1-z2)))
}
I have a data frame from which I make subsets.
When I call
subset(dataframe,cubic.distance(tb19h,tb37v,tb19v,190
Dear r-help,
I have the following function defined:
cubic.distance<-function(x1,y1,z1,x2,y2,z2) {
max(c(abs(x1-x2),abs(y1-y2),abs(z1-z2)))
}
I have a data frame from which I make subsets.
When I call
subset(dataframe,cubic.distance(tb19h,tb37v,tb19v,190,210,227)<=2)
I have the result with 0
