[R] unable to use functions require DLL from package

[Charlotte de Vries]

Hey there!

I'm having problems with the same code, but I get a different error: 

Error in .C("spline_coef", method = as.integer(method), n = n, x = 
as.double(x),  : 
  "spline_coef" not available for .C() for package "stats"


I'm using R3.1.0 on windows 8 and I've never used R before, so I might have 
made some terrible newby error (I have programmed quite a bit before, but in C 
and Matlab). 

Thank you!

Best, 
Lotte
