Hello, I am working on a simple non-parametric (Theil) regression function and and am following Hollander and Wolfe 1999 text. I would like some help making my function faster. I have compared with pre-packaged version from "MBLM", which isnt very fast either, but it appears mine is faster with N = 1000 (see results below). I plan on running this function repeatedly, and I generally

If you redefine your NAs as below to be detected as some arbitrary large number, then the code should work through. Any 5's left in your dataset can be replaced just as easily by NAs again. Not elegant, but effective. site <- c("s1", "s1", "s1", "s2","s2", "s2") pref <- c(1, 2, 3, 1, 2, 3) R1 <- c(NA, NA, 1, NA,NA,NA) R2

Hello, I'm not sure if this is the correct place to post this, but please help if you can. I have Ubuntu 10.04 OS and was running R version 2.13.1 (2011-07-08) Copyright (C) 2011 The R Foundation for Statistical Computing ISBN 3-900051-07-0 Platform: x86_64-pc-linux-gnu (64-bit) I recently had problems using install.packages() to get 'maps' and 'mapproj' anyway, long story

Hello Apologies if this is a simple question, I have searched the help and have not managed to work out a solution. Does anybody know an efficient method for reading many text files of the same format into one table/dataframe? I have around 90 files that contain continuous data over 3 months but that are split into individual days data and I need the whole 3 months in one file for
