...n, table$X. I wish to make a boxplot of (table$X ~ table$A) for a given value of B. Is there a way to express this with a formula, or is it necessary to manually extract the right lines in the table? In that case, what is the best way to do so?

..., X is a unitary price and Y is a quantity bought from city Ai at price Xi. I would like to make a boxplot of the prices ponderated by the quantity bought. Since it sounds like a fairly standard visualization, I suppose ther's an easy way to do this with R. Thank you for your help.

Hi, I have the following (probably trivial) problem: I am running a Windows 95 System and have setted the environment variables R_HOME and especillay R_USER in the autoexec.bat. The idea was, to invoke R at the startup to read in the files .Renviron and .Rprofile from my home directory, even when the current working directory is somewhere else. Subject to the manual it should work, but it does

...ot;, not "Color". Checking the logs I noticed it keeps using id = 1 ever after the first query. I really need this to work, but have run out of ideas. Any gurus out there willing to help? Could this be a bug in Rails or some cache feature I''m missing? Thanks in advance, Pedro Fayolle

I have re-built all the compiled packages for R 1.2.0 for Windows, and the set available in CRAN/bin/windows/contrib are now for rw1020. If you are upgrading to rw1020, please replace all the compiled packages you have downloaded by ones from this set. There a few packages available for the first time: RMySQL mlbench netCDF and a few that are not yet running on 1.2.0 on any platform hdf5

Dear sirs, My name is Marcelo Grimaldi and i work for General Electric in the Six Sigma Program. Recently I became very interested in spectral analysis, because I think it can be applied to my job. I use Minitab 12 and i have heard that writing macros for spectral analysis in this software is very difficult. Could I perform this analysis in a easier way throught "R" ? Have you ever

Hi, I have a big data file (over 30,000 records) looks like this: 100, 20, 46, 70 103, 0, 22, 45 117, -1, 34, 65 120, 15, 0, 25 113, 0, -1, 32 142, -1, -1, 55 ..... I want to read only those records having positive values in all of the four columns. That is, I don't want to read record # 3, 5, and 6 into R. However, when I type: read.csv("data.csv", sep=",")

Dear all, I am interested in reading Excel spreadsheets (*.xls) directly into R (I am using version 1.1.1 at the moment). I have not had much luck so far. For the time being, I have been converting Excel files to comma delimited files (*.csv) and reading these into R (using commands such as "read.csv"). This works well, but it would be more efficient if I could read the Excel files

Hello, I'm trying to do some correspondence analyis, with R, of course (by correspondence analysis, I'm refering to JP Benz?cri's methods, in case there might be some other thing with a similar name) I've found a couple of tools refering to C.A in the existing packages : ca() in package multiv and corresp()/mca() in MASS. MASS tools look more easy to use (it is supposed to put

Hi, I''m new to Rails and I have a question about the collection_remove method added to models with has_and_belongs_to_many associations.
