About the parameters of rotationMatrix

Hi,

Why does this not work? The values inside the rotationMatrix() doesn't 
seem to change:

library(rgl)

for(i in 1: 10)
{
     a2=i*0.1; b2=i*0.2; c2=i*0.3
     print(c(a2,b2,c2))
     UserMatrix = rotationMatrix(pi/4,a2,b2,c2)
     print(UserMatrix)
}

Yours,

Atte Tenkanen
