I am trying to understand the function acf stats:::acf shows me the function I am having trouble understanding the usage "$acf" in the following acf <- array(.C(R_acf, as.double(x), as.integer(sampleT), as.integer(nser), as.integer(lag.max), as.integer(type == "correlation"), acf = double((lag.max + 1L) * nser * nser), NAOK =

Hi I'm exporting some graphs from R to M$Word. I used png, jpeg and bmp and the quality is poor when comparing with the postscript. What is the best way to export a chart to be included in a M$Word file ? Thanks EJ

Hi I have a matrix (4 x 950) and I want to remove 3 rows, where the values from the first column are 713, 714 and 715. I can select the rows, one by one, with mat[mat$first==713,] mat[mat$first==714,] ... but I'm unable to (i) select the 3 rows at once, (ii) select the matrix excluding those rows. How can I do it ? Thanks EJ

Hi Maybe this is not an issue about R. It's probably a programming issue and I am not a developer at all. Anyway my main developing activities are in R and that's where I have difficulties. When I develop a function or group of functions I lose eternities with the objects attributes and classes. I do a lot of object manipulation (lists to arrays, factors to numeric vectors, etc, etc) so

Hi! I 've a problem to have a lognorm distribution with mean=1 and var (or sigma)=1. rlnorm(1000,0,0) rlnorm(1000,1,1) rlnorm(1000,0,1) .... ? Can you help me?

Hi The shapiro.test function outputs a value of the W statistic, which should be 1 if the distribution is normal, and a p-value for the test (as the documentation states). I'm a bit confused with some results. I'm getting a W=0.9977 and a p-value=0.1889. I was expecting that a W of 0.9977 would tell me that the distribution is normal so p-value should be small ... What am I missing ?

Hi, dear list members, I've been using R under windows XP and I am now changing my system to SUSE LINUX 9.3. I could figure out that there is no precompiled version of R for LINUX. To get me going, I would like your help regarding what I need to setup R under my SUSE LINUX. Which compiler do I need to be able to compile the source and I was wondering if I could get GNU compiler?

I have just put up a new executable as a replacement for the one in rseptbeta.zip there have only been a few changes; mostly to the menu's. I am about to start on a major overhaul including getting survival to work and grabbing the 0.60 version once it's stable. Please let me know about other enhancements you want.... robert

Hi I'm writing a function that uses four parameters (scalars) and I need to run it in an iterative process (the parameters vary to find the minimum RSS). I don't want to use loops and so tried the do.call function. However it didn't work. My understanding is that the do.call simple runs the function replacing the arguments (scalars by vectors), instead of runing the function for

Hi I wrote a function implementing an algoritm for simulation of spatial sampling plans (using geoR). I'm using a range of parameters to perform several simulation and sometimes this parameters create function errors wich cause the algoritm to stop. How can I avoid this ? Below there's a small example that I made to study the problem but I was not able to solve it. I've tried

Hello! I have two questions. First of all, I have a problem dealing with acf (Autocovariance function) and need help. First I defined a time series, x, which is a vector created by x <- ts(rnorm(200)). So I plugged the series directly into the acf function, acf(x) and an error message popped up as: Error in .C("acf", as.double(x), as.integer(sampleT), as.integer(nser), :
