nonparametetric bivariate regression
Hi there,
Does R has built-in codes for nonpara. bivariate regression so that I can
estimate the joint distribution of two variables as a function of some
covariates? Thanks a lot.

import data from splus
hi there,
anybody knows how to import data into R from splus directly? I have a huge
amount of data in splus format, which will cost forever for me to transform
the data back to ascii or something else and then read them into R.
thanks a lot.

generate a series of fucntion
Hi there,
I want to generate a large amount of functions,
say f=function(x,t) exp(-t[1]-t[2]*g_1(x)-t[3]*g_2(1+x))
where g_1(x) and g_2(x) are from a long list of moments, such as x, x^2,
log(x), log(1+x) .. and so on.
Any suggestions on how to do this efficiently?
thanks a lot.

compile c code from R
Hi,
Can I turn my R code automatically into C? If yes, how can I do that? Do I
benefit by doing it?
(I know I can do this in matlab and it increases the speed when there is a
lot of looping...)
thanks a lot.

My whole function is this:

exp<-function28(X,x,c,b)
if(max(exp)>=max(dexp(x,rate=1))){
