similar to: getting data frame rows out of a by object

Hi, there, Suppose I have two vector say x=c(1 2 3 4 5) and y=(2 3 6 7). Then I want to combine these two vector together and get z=c(1 2 3 4 5 6 7) with 2 and 3 only appear once. I want to extend this one to a general case(say more than 100 elements in x and y and each time I don't know which elements are the same). Do you happen to know how to do this and which command should use? Thank

I want to use question numbers from my survey data (fake data below) as markers in a scatterplot. I'm using "as.character" to convert question numbers to characters. However, plot truncates the 0 (zero) off of question 10. How can I get the ending zero so I can add questions 11 - 20? # Sample code below Question <- c(1,2,3,4,5,6,7,8,9,10) Performance <-

Hi. In a case like this, I can get strip headings that have the name "c" and the value for c. d <- data.frame(a=1:5,b=6:10,c=11:15) > xyplot(a ~ b | paste("c", c), data=d) > For more complicated examples, instead of using paste repeatedly I would like to use a function. It seems like what I really want is a macro, though. I'm not quite familiar enough

Hi. I am having trouble thinking of an easy way to grab rows out of a data frame. I want to select the rows with a median value when the rows are similar. A simple example is this table, which I could read into a data frame. I would like to find a new data frame with only the rows with a median value for the "c" column given a certain "a" value. For example, the c values

Hello Spse I have a matrix, say 1 2 3 4 5 6 7 8 9 and I would like to expand it by repeating rows within the matrix, to get, if the repeating factor is 2, say: 123 123 456 456 789 789 (or columnwise as well) . There must be a smart way of doing that? Many thanks Juhana Vartiainen juhana.vartiainen at labour.fi -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

Hello, I run R on Windows 2000. When I load lattice library and plot some lme class objects, the graphic window displays a dark-green color. Graphics look ok on the screen, but lines and points become invisible whem I send the plot to a printer because of the background color. Are there ways to reset the background color? Both par(bg=) and windows() do not work. Any ideas? Richard

Hi. I'm writing an article on network backups, and instead of using my old ssh1 software, I decided to go with openssh all the way. I got the hang of the openssh way of doing protocol 2 public key authentication, but ssh is failing to terminate when a pipe is broken. I am ssh-ing to a remote host and doing a cat or zcat of a dump file, then on the localhost, I'm using restore to extract

I have a small problem. I am running glm() in R-0.61.0 on Redhat 4.2. I want to get the standard errors from the output. If I do out <- glm(....) summary(out) I get the coefficients printed as well as their correlation matrix. If I do out$coefficients I get the coefficients out$fitted gives me the fitted values I can then assign the fitted values or the value of the estimated

Hello everybody, I am doing a plot and I would like to know which parameter I have to use in order to get an equal scale for the axes x and y: Means, if the intervals in the x-axis is 0,5,10,15.... I would like to have the same scale for the y-axis. Thank you so much for your help. Halima from Leiden where the sun is shining. Holland

In the source code perhaps? :-) You can find a pretty precise description in the article Robert and I did in JCGS. Actually its pretty simple. Functions have access to the variables which were in effect when the function was defined. f <-

I want to do something like this in R. If I have three vectors > a1 [1] 1 2 3 > a2 [1] 4 5 6 > a3 [1] 9 10 7 I want to compute 1. A vector that is the mean at each serial position of a1, a2, and a3. so in this example it would have the contents 4.667, 5.667, 5.333333 2. A vector that is the SD at each serial position of a1, a2, and a3. so in this example it would have the contents

Hi, I have just seen Stefan Steinhaus' web page : http://www.uni-franfurt.de/~stst/ncrunch.html I think it would be nice to include "R" as well. I have taken Forrest Young's email on stat-lisp list and changed the stuff for "R" :) Here it is: (someone please check this so we can also send it to Stefan Steinhaus.
