Subject: Error using lm(z~x+y,data)
Hi!
I am fitting a plane to a surface:
This works excellent:
---------------------------------
x<-dataframe[,1]
y<-dataframe[,2]
z<-dataframe[,3]
data<-cbind(x,y,z)
# Fit plane to surface
result<-lm(z~x+y,data)
---------------------------------
But I need to rescale the x,y parameters. So:
-----------------------------
x<-dataframe[,1]*149
y<-dataframe[,2]*149
z<-dataframe[,3]
data<-cbind(x,y,z)
# Fit plane to surface
result<-lm(z~x+y,data)
----------------------------------
And surprisingly this does not work. Error message is:
Error in eval(attr(formula, "variables"), data, env) :
sys.frame: not that many enclosing functions
Why does this happen?
kind regards
