These are experimental sparse smoothing functions, and should be left well alone!
spasm.construct(object,data)
spasm.sp(object,sp,w=rep(1,object$nobs),get.trH=TRUE,block=0,centre=FALSE)
spasm.smooth(object,X,residual=FALSE,block=0)
sparse smooth object
data frame
smoothing parameter value
optional weights
Should (estimated) trace of sparse smoother matrix be returned
index of block, 0 for all blocks
should sparse smooth be centred?
what to smooth
apply residual operation?
It is not recommended to use these yet
