spasm.construct

Experimental sparse smoothers

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)

`object`	sparse smooth object
`data`	data frame
`sp`	smoothing parameter value
`w`	optional weights
`get.trH`	Should (estimated) trace of sparse smoother matrix be returned
`block`	index of block, 0 for all blocks
`centre`	should sparse smooth be centred?
`X`	what to smooth
`residual`	apply residual operation?

It is not recommended to use these yet
