When writing Ruby you have the option to end the file early with __END__. Anything after the __END__ is assigned to a constant called DATA which is available within the file. I recently tried using this in Rails and it didn''t work. Instead I get an uninitialized constant exception. Anyone know why? Has it been disabled in Rails? thanks Gavin

Hello, When I call an action with some invalid XML or JSON data a parse exception gets raised from within Rails/Ruby (REXML or ActiveSupport::JSON). The problem that I''ve got is how to handle these exceptions. In my application_controller.rb I have the following for debugging purposes: def rescue_action_in_public(exception) respond_to do |request| request.all { render :text =>

Hi, My network has samba 2.2.2 installed on Sun with lprng and NT 4.0 workstations. Samba acts as PDC for these workstations. I am using priting through samba. I am using 'disable spoolss = yes' option which means the drivers are on installed on client side and are not downloaded from the server. So all these printers (on Samba) act as Local printers on NT machines. As I am

Hello all, I have some histograms of amount of DNA in some cells (DU145 cells overexpressing Bax and Bcl-xL for those who wish to know). The histograms show not only two peaks as expected, but three, indicating that some cells have more than normal amounts of DNA. I am interested in knowing how much of the cell populations are in each peak as well as between. I am not really sure how to go

Hello everyone,  I'm working in a project to create an special analysis about visualization in some animals and its behaviour, through checking eye movement. The point is this is very important to get data from the image as a resume of what this animal sees. I think an RGB histogram like photoshop does, but I need to get the data from this histogram analysis and I was wondering about using R

Hi all, I have installed RODBC package. But am not able to connect it for using MySQL. For accessing MySQL Db a connector is required.For that can i use the mysql db which is a part of WAMP server or use separate mysql db. I know there is a package called RMySQL. But i find it very difficult to install the RMySQL package under .Which is better one for accessing MySQL Database. Thanks Amrita

Hi Folks, I'm wondering if there are people out there who would be interested in what would be involved in developing an interface between R graphics and the 'pic' language. Explanation; 'pic' has been part of the Unix 'troff' typesetting suite since very early days (1970s), and also of the GNU troff: 'groff'. Its function is to act as a preprocessor,

Hello, I'm a new R user and I'm having a little trouble getting started. I'm hoping someone can help me out. I read numbers (integer) from a SQL database. Some calculations as mean()are possible but hist() give an error. Here are the commands: library(RMySQL) Loading required package: DBI > con <- dbConnect(dbDriver("MySQL"), dbname = "test") >

i'm actually new at R, but to me its going to be big time, i want to do an analysis for the attached data, like define variables and then analyse get means, variances, histogram, and other important attributes including cross tabs Regards, Peter -------------- next part --------------

I am not sure if I should ask this question in this list. But I'll try. Currently I am trying to analyze images using EBImage and biOps. One of the features that I need to extract from various images is the color spectrum, namely, which colors each image consists of. So, each image hopefully can be converted into some sort of color histogram so that color ingredients are easily comparable

I am trying to do a histogram lattice plot and I would like the histogram to be filled with a different colour in each panel. Note: I want every bar in each histogram to be the same colour, but that there should be different colours *between* histograms. Can't seem to get this to work. I thought that something like the following would be a goer: set.seed(42) X <- rnorm(200) A <-

been puzzling over this for a day. Summary integer variable to use with histogram, 170,000 rows. Value is day of year. Hist works, lattice histogram with nint does not work (spurious spikes in display), lattice histogram using breaks=c(0:365) works fine. Spike values appear to be sum of two adjacent bins. Want to know if this is a familiar problem, and what the recommended work-around is.

Dear all, I have done further modifications on the histogram functions that I reported earlier this year, and I hope this can be of use and perhaps included in the distribution. I have been using this stuff a couple of months myself, and while it is nothing sophisticated, it has it's applications. :-) I did a few small modifications today to make it a bit more compact. I have modified the

Hi I would like to superimpose group-specific densityplots on top of an overall histogram using panel.histogram and panel.densityplot. Furthermore, I would like to automatically adjust the range of the y-axis to take into account the ranges of both histogram and densityplot. This last part is where I have a problem. I believe using the prepanel argument of histogram is typically the way to go,

Hey everyone, So i cant figure this out. when using histogram() from lattice instead of hist() i get what i want as far as output. But using histogram i can seem to be able to figure out how to get multiple plots on the same panel. So par(mfrow=c(3,2)) for (i in 1:20) hist(rnorm(100),main="",cex.axis=.8) gets me about what i want but i want to use histogram() cause it gives
