Problem with Slope.test function
Hi all,
I need to test the significnce of difference between slopes of two regression lines and regression line with theoretical line. I try to use Slope.test function from emu package,
but an error occured...
library(emu)
d1<-data.frame(P1=c(1,2,3,5,7,8,9,13,14,15),
P2=c(1,2,5,8,11,13,15,15,18,24),
R=c(2,7,8,9,16,21,27,31,33,36)) # First data set
m1<-lm(R~P1+P2+P1*P2,data=d1) # Regr.
