similar to: how to strip list from NA values looking only at one column ?

many languages have shorthands for that operation like: variable += 1 or ++variable is there something like that in R ? -- View this message in context: http://r.789695.n4.nabble.com/increase-or-decrease-variable-by-1-tp3076390p3076390.html Sent from the R help mailing list archive at Nabble.com.

I have an issue with W2K/XP using Folder Redirection to a Samba homes share (or any share for that matter). This is only a problem when access for a user is via an ACE (ACL) and not the traditional file system permissions.

In datamatrix[, "y"] == datamatrix[, "y"][-1] : longer object length is not a multiple of shorter object length out = c(FALSE,datamatrix[,'y'] == datamatrix[,'y'][-1]) and I do not know why I get that error, the resulting out matrix is somehow one row larger than datamatrix... all I try to do is filter matrix by dropping rows where [,'y'][-1] ==

consider this matrix: [,1] [,2] [1,] 3 7 [2,] 6 5 [3,] 7 5 [4,] 3 5 [5,] 7 5 [6,] 5 5 [7,] 8 4 [8,] 2 4 [9,] 7 4 [10,] 0 6 I need to delete all rows where column 2 above and below has the same value, so the effect would be: [,1] [,2] [1,] 3 7 [2,] 6 5 [6,] 5 5 [7,] 8 4 [9,] 7 4 [10,] 0 6

I know that by setting alpha to for example col = rgb(0, 0, 0, 0.1) it is possible to see how many overlapping is in the plot. But disadvantage of it is that single points are barely visible on the background. So I wonder if there is possible to make setting that single points would be almost black, but with more and more data on the same spot it would get more and more whiteish. Or maybe it is

Hi All I have been struggling with this model for some time now and I just can't get it to work correctly. The messages I get when running the code is: DLSODA- Warning..Internal T (=R1) and H (=R2) are such that in the machine, T + H = T on the next step (H = step size). Solver will continue anyway. In above message, R = [1] 0 0 DINTDY- T (=R1) illegal In above message, R = [1]

I know little of statistics and have created this function out of intuition. But since this algorithm is so basic I wonder what is the proper name of this function and is it build in R. here is some code in PHP to illustrate what the function is doing, it uses some function I created but the meaning is obvious: #get csv file and interchange rows with columns to get two arrays $csv =

my csv file is very simple - just one line for purpose of this test: 0{TAB}0 and read function is this: csvdata = read.csv(file="d:/s/test.csv",head=FALSE,sep="\t") then error comes: Error in source("d:/test.csv") : d:/test.csv:1:9: unexpected numeric constant 1: 0 0 but when I change delimiter to ; (colon) then error not shows up anymore -- View this

Hola. Una manera puede ser tomar una lista de todos los archivos de un directorio y trabajar con ellos, puesto que ciertamente existen. ¿Cómo? Supongamos que tienes una carpeta llena de archivos csv. Entonces, puedes guardar el nombre de tus archivos en un objeto con lista_archivos<-dir() > y esto te dará todos los csv de esa carpeta (si tienes otros archivos también estarán allí, pero

This is slightly off topic since I am all the way upto the login prompt, but I appeal to you all because you probably have experience in this: I am passing a diskless workstation a compressed root filesystem that is copied from a server (chopped down). I am only intereted in text consoles being available on the client (runlevel 3). The diskless workstation goes well up to the login: RedHat
