similar to: Applying some equations over all unique combinations of 4 variables

A stupid question but I just cannot see how to do this. I have a loop that does some calculations and puts the results in a vector for each iteration, but I cannot see how to get the data out of the loop in such a way that I can use it. I can print it but how do I get it into a set of vectors or what ever. Any help gratefully received. Thanks Example cata <- c( 3,5,6,8,0, NA) catb <-

I am stuck on a simple problem where an example works fine but the real one does not. I have a data.frame where I wish to sum up some values across the rows and create a new data.frame with some of old data.frame variables and the new summed variable. It works fine in my simple example but I am doing something wrong in the real world. In the real world I am loading a labeled data.frame. The

I have a simple data base and I want to produce tables for each variable. I wrote a simple function fn1 <- function(x) {table(x)} where x is a matrix or data.frame. and used apply to produce a list of tables. Example below. How do I apply the colnames from the matrix or names from the data.frame to label the tables in the results in the list. I know that I can do this individually but

This is probably a simple problem but I don't see a solution. I have a data.frame with a number of columns where I would like 0 <- NA thus I have df1[,144:157] <- NA if df1[, 144: 157] ==0 and df1[, 190:198] <- NA if df1[, 190:198] ==0 but I cannot figure out a way do this. cata <- c( 1,1,6,1,1,NA) catb <- c( 1,2,3,4,5,6) doga <- c(3,5,3,6,4, 0) dogb <- c(2,4,6,8,10,

Dear R'sians, Would really appreciate if you could suggest a more efficient way to order the columns of a dataset. The column names of the dataset contain indices separated by a period. Following are examples of my code and the dataset. oC <- function(tg=x2) { lth <- length(grep("T",names(tg))) thix <-

I want to calculate the "scat" etc, values for each level of id, output a vector of these values that is a <- c(scat, sdog, srat, sbat ) and do an rbind on them. Each level of id has a different value of rate. So far it it looks to me like I can do this by a series of repeated subsets of Df butI would think that I should be able to do this with a function but I am not having

This is how I get the month names from within R: > mon <- rep(strptime("01/01/1952", format = "%d/%m/%Y"), 12) > mon$mon <- mon$mon + 0:11 > mnam <- months(mon, abbreviate = F) > mnam [1] "januar" "februar" "marts" "april" "maj" "juni" "juli" "august"

hi I plot a series of observation data every minutes in a day as the attachment below plot(wnd,type='l',lty=1,col='red',lwd=1,xlab=xxlab,ylab=yylab,ylim=YY) In the figure, the x-axis tickment is the number of data How can I change it fore example 1h 2h 3h 4h and so on ? -- TANG Jie Email: totangjie at gmail.com Tel: 0086-2154896104 Shanghai Typhoon Institute,China

The disaster in the Gulf coast and the less than optimal initial response suggests to me that citizens must shoulder more responsibility for emergency management. Communications loss must have played a large role in the failures that occurred. I can't help but wonder if there are fewer ham radio operators today and that if there were more, maybe they could make a difference in future

Hello everyone, please keep my CC'd, I'm not on the list. I've been using dovecot happily via an ssh tunnel. My mutt is configured to use IMAP, and the tunnel is as follows in my muttrc: set tunnel="ssh -q mymailhost 'MBOX_LOCKS=fcntl MAIL=/home/jlbec/mail /usr/libexec/dovecot/imap'" It should be pretty obvious that this logs into mymailhost as me (via SSH

Hi Dennis, SOLVED!!! My thanks to both you, John, and others who chimed in. Took a little more digging before finally working, but it is working! Here's a little more of what I did and the ultimate resolutions: I installed the reshape2 library from CRAN. Executed > (.packages()) [1] "reshape2" "stats" "graphics" "grDevices"

This probably is a postfix problem, but I think there are lots of postfix experts/users on this list, and have heard a lot good things about this list, so I am just giving it a try. Thanks in advance! I am using dovecot-1.0.0-8_56.src.rpm downloaded from atrpms.net, and rebuilt from it(rpmrebuild ...). Postfix is 2.4.3. I followed documents at http://wiki.dovecot.org/LDA and LDA/Postfix, and

That was not helpful - I explained that I had to run this version.

I'm comparing R-1.3.0 on Solaris 2.6 to R-1.3.1 on WindowsNT. The following 5-line script returns TRUE on Unix but FALSE on NT: fnam <- tempfile() file.create(fnam) txt <- paste("file.exists(\"", fnam, "\")", sep="") expr <- parse(text=txt) eval(expr) The issue seems to be that backslashes get lost in the parsing. A workaround is to change

I am trying to call a funtion within another function and I clearly am misunderstanding what I should do. Below is a simple example. I know lstfun works on its own but I cannot seem to figure out how to get it to work within ukn. Basically I need to create the variable "nts". I have probably missed something simple in the Intro or FAQ. Any help would be much appreciated. EXAMPLE

it seems wow is moving towards GLL for the Macs and could be dropping the normal OpenGL. how is this going to effect running WOW with wine ? right now running wow under directX is painful and so slow on my system thats it just not a option.

Running Ubuntu 10.04, Nvidia driver version 260.19.29, 3 GB RAM, AMD Phenom Quad-Core, wine-1.3.11. I notice no difference in performance whether OpenGL is enabled or not. Does this mean D3D is now working and I don't need OpenGL now? I get close to 80fps in some places, which is great, but in a raid or other places with a lot of toons and activitiy, Wow practically freezes up and becomes
