After loading locfit, I am unable to access functions within locfit.
following
http://www.herine.net/locfit/start.html
> library("locfit")
> x <- 10*runif(100)
> y <- 5*sin(x)+rnorm(100)
> fit <- smooth.lf(x,y)
Error: couldn't find function "smooth.lf"
> fit <- locfit(y~lp(x))
Error in eval(expr, envir, enclos) : couldn't find function "lp"
library() or package manager GUI tells me locfit is loaded
Any ideas on how to fix this ?
