[R] gam step in grasper

[Martin Wegmann]

hello, 

some weeks ago I asked if there is an equivalent of step(lm) for gam, and 
Simon Wood informed me that there isn't but it will eventually be done.

Now I found grasp.step.gam {grasper} and wonder if it would be possible to 
rewrite/extract (? I don't now how it is called or how it works - I am not 
experienced in programming) this command for the use outside GRASP-R. 
Perhaps this way is less work intensive but of course this command doesn't use 
GCV/UBRE scores but anova.
Is there an argument not to use this function inside GRASP-R even though it's 
purpose is not spatial?

thanks for your help, cheers Martin
