R-beta: problem with locfit

A second problem is that the R (0.61.1) model.extract() function differs
from the
S version, and the cens argument won't be interpreted properly. Adding
the following
modified model.extract() to the locfit/R/lfrsup.r file should work...

Here is a more general solution to the model.extract problem, rather than
forcing developers to edit model.extract every time they introduce a new
argument.

model.extract<- function (frame, component) 
{
        component <- as.character(substitute(component))
        rval <- switch(component, response = model.response(frame), 
                offset = model.offset(frame), weights = frame$"(weights)", 
                start = frame$"(start)")
        if (is.null(rval)) {
                name <- paste("frame$\"(", component, ")\"", 
                        sep = "")
                rval <- eval(parse(text = name)[1])
        }
        if (length(rval) == nrow(frame)) 
                names(rval) <- attr(frame, "row.names")
        else if (is.matrix(rval) && nrow(rval) == nrow(frame)) {
                t1 <- dimnames(rval)
                dimnames(rval) <- list(attr(frame, "row.names"), 
                        t1[[2]])
        }
        return(rval)
}
