[R] Extracting Data form Simpleboot Output
Hello, I am new to R, so forgive my ignorance on what is probably simple. I find package simpleboot quite useful for LOESS bootstrapping and generation of plots. I want to calculate the standard error for x=60 of the 100 grid points and 50 bootstraps. The code below gives the first fitted value. How can I grab the other 49 values easily? I could do it one at a time for 50 bootstraps, but this becomes tedious for say 2000 bootstraps. Thanks for any help. library(simpleboot) library(bootstrap) attach(cholost) set.seed(13579) lo <- loess(y ~ z, data=cholost, span=.5, degree=2, family="gaussian", method="loess") lo.b <- loess.boot(lo, R=50, rows = TRUE, new.xpts = NULL, ngrid = 100, weights = NULL) lo.b$boot.list$"1"$fitted[60] -- Terry W.
