Hi RUsers, I am wonder if I can search observations whose IDs matches any of the values in another vector, such as in MySQL. While I am learing MySQL for future database management, I appreciate if anyone could give me a hint. Suppose I have one 5*1 vector containing observation IDs and frequencies, and one 3*1 vector containing observation IDs. observation<-c(1,2,3,4,5) ID<-c(1,3,4)

Hi R users, I appreciate if you could give me some hint/help on this string operation. Suppose I have a list of string objects in varying sizes like [[1]] [1] "A" [2] "B" [3] "C" [[2]] [1] "D" [2] "E" [[3]] [1] "F" Then I would like to create a vector that contains all elements like [1] "A" "B" "C"

Hi, I just wonder if this is a rounding error by the princomp command in R. Although this does not make much sense, using a hypothetical dataset, a, a<-matrix(runif(1000),100,10) I did PCA with the princomp, and compared it with the results estimated with the eigen and the prcomp commands. And I found some differences in the results: opposite signs in the loadings; slight differences in

Hi, I am trying to install RSQLite package on my Fedora workstation. I tried to install other packages as well, but each time I got the same error messages saying "compilation error" and "non zero exit status". Do I have to specify "lib="?

Greetings all. I have been running Wine under Kubuntu Feisty for about the last four months, keeping it updated with the latest wine releases on a weekly basis, I use it to run WordPerfect. Whilst WordPerfect didn't run flawlessly, I got it to work well enough to edit and save documents I work on at home. In four months none of the updates to Wine changed anything in how WordPerfect

Dear R-users I have four simple linear models, which are all in the form of a*X+b The estimated parameter vectors are a <- c(1,2,3,4) b <- c(4,3,2,1) My goal is to draw a plot where x-axis is X (range from -100 to 100) and y-axis is the sum of all four linear models X <- seq(-100,100, length=10000) plot(X, sum of the four linear functions) I started with a function for summing

Hi R users Having both a faster CPU and more memory will boost computing power. I was wondering if only adding more memory (1GB -> 2GB) will significantly reduce R computation time?

I read on lwn.net that swfdec has support for watching youtube.com videos. Good work! I have not been able to get the Adobe 32-bit mozilla plugin working under 64-bit gutsy so I figured I'd give swfdec a go. A quick search of the archives and bugzilla turns up nothing obviously similar to my problem. Viewing this page: http://www.youtube.com/watch?v=82Opqy5mFZM&feature=related I

Dear R-users I need to read some text files produced by some other software. I used readLines (with n = -1 ) command and then tried to find some numbers I liked to extract or some line numbers I like to know. The problem is that there is no empty line at the end of the text files. R gave me this warning below; In addition: Warning message: incomplete final line found by readLines on

Dear R-users, I am looking for a way to scan a directory and then make a string vector consisting of the file names in the directory. For example, under c:\temp\ there are 4 files a.txt, b.txt, c.txt, and d.txt I would like to have a string vector c("a.txt","b.txt","c.txt","d.txt") How do I do that? Thanks Taka,
