Hello all, I have written a for loop to act on a dataframe with close to 3million rows and 6 columns and I would like to pass it to apply() to speed the process up (I let the loop run for 2 days before stopping it and it had only gone through 200,000 rows) but I am really struggling to find a way to pass the arguments. Below are the loop and the head of the dataframe I am working on. Any hints

I am running a simple SQL SELECT statement that involvs 50k + data points using R and the RJDBC interface. I am facing very slow response times in both the RGUI and the R console. When running this SQL statement directly in a SQL client I have processing times that are a lot lot faster (which means that the SQL statement itself is not the problem). Did any of you compare RJDBC vs RMySQL or is

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.

Here is what happens: > r=sqldf("select ... ") Loading required package: tcltk Loading Tcl/Tk interface ... Then

Hello Everyone, We have recently purchased a server which has 64GB of memory running a 64bit OS and I have compiled R from source with the following config ./configure --prefix=/usr/local/R-2.9.1 --enable-Rshlib --enable-BLAS-shlib --enable-shared --with-readline --with-iconv --with-x --with-tcktk --with-aqua --with-libpng --with-jpeglib and I would like to verify that I can use

Hello; I'm now using mainly R for windows, mainly because I'm writing a tcl/Tk interface for some people, and I've got two questions. I'm an absolute beginner with tctk or tcktk use under the R GUI. 1) Is it posible to create a shorcut that launchs the R GUI and automatically reads the "source code" of the tcl/tk script to also launch the tcltk interface? 2) Is the

The marilith boxes use a conserver (http://www.conserver.com/) setup for serial access. Our installation exports the logs via http allowing us to grab them with wget. Sending debug keys with is handled separately via xenuse. xenuse ultimately speaks to the conserver too but it abstracts away the IP and port to use so this is preferred. With these changes the correct Serial hostprop for a

I would like to use R.oo and tcltk to implement a Turtle World. I have encountered many problems because: 1) I am not sure how to implement static fields with R.oo 2) I am not sure how to implement a constructor that would call a function only for the first instance of a class (i.e., to initialize value of static fields only once) 3) I am not sure how to remove/delete cleanly existing
