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 I bought a new laptop HP dv9500 just a week ago and installed a Ubuntu gutsy ribbon on this laptop. I wanted to install Fedora but there are more threads on Ubuntu, so I decided to install Ubuntu. After hours of struggle in configuring x server/graphic card stuff, I installed R for Gutsy ribbon using "sudo apt-get install g77 r-core'. Now when I tried to install 'sp' package

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="? I never specified the library path before when I was using Fedora Core 6. Warning in install.packages("RSQLite")

Rusers: I am trying to apply a quadratic discriminant function to find the best classification outcomes. 1 is assigned to the values greater than a threshold value; and 0 otherwise. I would like to see how the apparent error rates and the optimal error rate change with increasing threshold values. I have a 1000*10 data matrix: n=1000 and p=10. Here is what I wrote so far, but seems to be

Hi, I am looking for clustering techniques that are tolerant to large datasets (500,000 unique customers with transaction records). I basically would like to conduct customer segmentation based on their transaction history - what they bought, how often they visited stores, demographics etc. And transaction part of the data is binary: 1 if they bought, let's say, fruits etc. Now the problem
