Hi. I can quickly create a by object that selects rows from a data frame. After that, though, I don't know how to merge the rows back into a data frame that I can use. Here is an example where there is a data frame with three columns, a, b, and c. I update it so that there are two rows for each combination of a and b. I use by to select the subgroups of rows that share the same a and b

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 <-

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

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 -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

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 <-

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.
