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")

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

Dear R-users, I have encountered the following problem every now and then. But I was dealing with a very small dataset before, so it wasn't a problem (I just edited the dataset in Openoffice speadsheet). This time I have to deal with many large datasets containing commuting flow data. I appreciate if anyone could give me a hint or clue to get out of this problem. I have a .dat file

Rusers, I am trying to append multiple .csv files of different dimensions (but # of columns are the same for all .csv files). I do have .csv files whose names are CA1.csv ~ CA100.csv. CA means california and 1 means the first file. So what I have been doing (after googling how to append by row multiple files) was: cleanup_data<-function(state,count) { out<-matrix() for (i in 1:

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, This is a very fundamental question. I want to export graphical results so that I can place them in an openoffice document. I use Fedora 5. Can anyone help? Thanks in advance. ------------------------------------ Takatsugu Kobayashi PhD Student Indiana University, Dept. Geography

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, Let me apologize for this simple question. I use 64 bit R on my Fedora Core 6 Linux workstation. A 64 bit R has saved a lot of time. I am sure this is a lot to do with my memory limit, but I cannot import 4.8GB. My workstation has a 8GB RAM, Athlon X2 5600, and 1200W PSU. This PC configuration is the best I could get. I know a bit of C and Perl. Should I use C or Perl to manage this

Dear All, Is sqldf equipped with delete queries? I have tried delete queries but with no success. Thanks in advance, Paul

This is my first post. I am running Mac OS X version 10.6.3. I am running R 2.11.0 GUI 1.33 64 bit. This may or may not be related to sqldf, but I experienced this problem while attempting to use an sqldf query. The same code runs with no problem on my Windows machine. Here is what happens: > r=sqldf("select ... ") Loading required package: tcltk Loading Tcl/Tk interface ... Then

Dear All, When one loads certain packages, some other dependent packages are loaded as well. Is there some way of detaching them automatically when one detaches the first package loaded? For instance, > library(sqldf) Loading required package: RSQLite Loading required package: DBI Loading required package: gsubfn Loading required package: proto but > detach(package:sqldf) > >

Dear all, I have a repository file (let's call it repo.txt) that contain two columns like this: # tag value AAA 0.2 AAT 0.3 AAC 0.02 AAG 0.02 ATA 0.3 ATT 0.7 Given another query vector > qr <- c("AAC", "ATT") I would like to find the corresponding value for each query above, yielding: 0.02 0.7 However, I want to avoid slurping whole repo.txt

Dear R-list, Does somebody know how can I read a HUGE data set using R? It is a hapmap data set (txt format) which is around 4GB. After read it, I need to delete some specific rows and columns. I'm running R 2.6.2 patched over XP SP2 using a 2.4 GHz Core 2-Duo processor and 4GB RAM. Any suggestion would be appreciated. Thanks in advance, Jorge [[alternative HTML version deleted]]

Hi, I'm working in R 2.11.1 x64 on Windows x86_64-pc-mingw32. I'm trying to insert a very large CSV file into a SQLite database. I'm pretty new to working with databases in R, so I apologize if I'm overlooking something obvious here. I'm trying to work with the American Community Survey data, which is two 1.3GB csv files. I have enough RAM to read one of them into memory,

I have two data frame A and B adn want to cross them. A has format as: a1 a2 a3 1 2 3 2 3 1 1 3 2 ... B: b1 b2 1 2 2 1 ... the combine result shall be something like a1 a2 a3 b1 b2 1 2 3 1 2 1 2 3 2 1 2 3 1 1 2 2 3 1 2 1 1 3 2 1 2 1 3 2 2 1 .... is there a function able of doing this instead of loops? Thanks, Sun
