Dear Rlisters, When trying to indicate which data belong to which of 7 groups, the following plot shows only 5 groups: ss <- trellis.par.get("superpose.symbol") ss$col <- c("red","blue","green","yellow","orange","magenta","cyan") ss$pch <- format(1:7) ss$cex <- 1.2 ss <-

Hi guys, Have the following problem computing vectors with pure vector algebra and end up reverting to recursion or for-looping. Function my_cumsum calculates a weighted average (W) of ratios (R), but only up to the given size/volume (v). Now I recurse into the vector (from left to right) with what you have left from the difference of volume minus current weight, and stop when the difference is

Greetings RListers, I have a data set containing two types of outcomes; success and failure. Associated with each outcome are 12 different measurements. I'm trying to find out, for example, if some of the 12 measures are associated more with success or failure or, if there's any relationship at all between the measures and the outcomes (success or failure). I don't have (as yet)

Hello, Rlisters I have to compute p-values that are on the tail of the distribution, P-values < 10^-20. However, my current implementations enable one to estimate P-values up to 10^-12, or so. A typical example is found below, where t is my critical value. ########### example - code adapted from Rassoc ####################### rho01 = 0.5 rho105 = 0.5 rho005 = 0.5 t = 8 z = 2

Hi, We got a huge problem on our sun grid engine cluster with glusterfs 3.3.0. Could somebody help me? Based on my understanding, if a folder is removed and recreated on other client node, a program that tries to create a new file under the folder fails very often. We partially fixed this problem by "ls" the folder before doing anything in our command, however, Sun Grid Engine

Hi, everyone I've been trying to make a scatter plot of POSIXct format data to see the difference between two start time. Like X: [1] "1995-05-26 19:00:00" "1995-05-27 01:00:00" "1995-05-27 07:00:00" [4] "1995-06-29 01:00:00" "1995-06-29 07:00:00" "1995-06-30 13:00:00" [7] "1995-06-30 19:00:00" "1995-07-01

hi all, I'm working on scrapping some website data to build a database. Under most cases, I can use package XML to get the dataset. However, some of the website doesn't give a explicit address of the downloaded tables. To be more specific, for example, I'm interested in the website http://ets.aeso.ca/ The data we are scraping is the "Pool Weekly Summary" under the

Is there any routine to generate for one vector matrix. If I have X I want to generate start from zero to maximum value each vector. For example, I have a vector x = (4,2,3,1,4) I want to generate n=6 times, for 4, start 0 to 4, then 2 start 0 to 2, ect. The result something like this: generate(x,n=6) 1,1,2,1,4 1,2,3,0,3 4,0,1,1,1 3,1,0,1,4 0,0,3,0,0 4,1,3,0,4 Could anyone help me. Thanks.

Hi, I want to use Princomp function in R, but com up an error as " Error: couldn't find function "princomp" ", can you help me resolve this problem? Thanks, Jixin Dai, Ph.D

Hi Vinod, Bjorn, Patrice, This patchset adds support for the Flexible Direct Memory Access (FDMA) core found on STi chipsets from STMicroelectronics. The FDMA is a slim core CPU with a dedicated firmware. It is a general purpose DMA controller supporting 16 independent channels and data can be moved from memory to memory or between memory and paced latency critical real time targets. After quite

Hi, everyone I got some problems when trying to subscript the value of vector and list, by using calculated indices. Here is the vector I am generated lon<-rep(0,886);lat<-rep(0,691) for (i in 1:886){ lon[i]<-112+0.05*(i-1) } for (i in 691:1){ lat[i]<--44.5+0.05*(691-i) } For a given location of lon(xp) and lat(yp), I would like to calculate the position of them,

I am an initial user of R. Could you give me some explanations or examples on how to solve the first order differential equations by the first-order Runge-Kutta method? Thank you very much Kind regards

Hi, Is there a quick way to go from this matrix: > A [,1] [,2] [,3] [1,] 1 1 1 [2,] 2 2 2 [3,] 3 3 3 [4,] 4 4 4 [5,] 5 NA 5 [6,] NA NA 6 [7,] NA NA NA to this matrix: > B [,1] [,2] [,3] [1,] 1 NA NA [2,] 2 NA 1 [3,] 3 1 2 [4,] 4 2 3 [5,] 5 3 4 [6,] NA 4 5 [7,] NA NA 6

Hi, let's say I have this A = matrix(c(1, 2, 4), nrow=1) colnames(A)=c("YOO1", "YOO2", "YOO3") # ie # YOO1 YOO2 YOO3 #[1,] 1 2 4 HELLO <- NULL HELLO$YOO1="BOO" HELLO$YOO2="BOO" HELLO$YOO3="HOO" and I want a matrix that will sum my categorization.. how can I do it efficiently without any loop? #ie BOO HOO
