Hi, I am wanting to look at frequent item sets using the arules package. I need to transform my data into a "transactions" object. The data I read in from a file has 2 columns, an ID and an item. How do I convert data like this into a transactions object? I've tried class? transactions but it only confuses me. My data is like this.... basketID item 1 bread 1 cheese 1 milk 2

I am new to generalized linear models and studying McCullagh & Nelder (1989). Especially, I have a problem resembling the \"cheese taste\" example (5.3.1. p. 109) of the book. I tried to analyse the cheese example with R but failed to do so because R allowed me to use logit link function only with binary family that supposes 0 <= y <= 1. Do I need to scale the y\'s or

greetings, i have run into same problem as a friend who bought a logitech c310 webcam. he told me about them being on sale, so i decided to buy one also. the 2 webcam programs that i have installed from repos are 'camorama' and 'cheese'. both work well for single photos, but i can not get 'cheese' to make smooth, continuous video recording. what is recorded is a jerky

Hi, Very so often when i am plotting something, doing a histogram, or whatever i am struggling to find out which are the numbers for different colors, palette names, types of lines, symbols, etc. Is there any documentation on line with all these numbers / names and the associated symbol / color??? For example if i am using the command image it uses a palette from red to yellow, with red the

Ok, so I finally got the id3/mp3 end of things worked out for the next release of QTagger and I'm back to implementing tag reading for Ogg Vorbis. I've got some code that will read tags, but I haven't been able to figure out how to write them. Here's the code that I'm using. It's a fine C/C++ mix. The code will eventually be in a C++ app, so I don't mind

Hi guys I'm trying to figure out how I can use probabilistic searching on a given field within a document; I've written to the list about this before, but haven't quite figured out what's required and, following a little research, I think I understand what I need to do but I'd like a clarification on this. o We have a database of a number of documents, with fields: title,

OK, I plugged in a web cam device (something called a 'Zoomy' -- a web cam/microscope). It is recognized by the unc driver. Now what? Does there exist a program that can use this device? Or do I have to write one from scratch? I have been searching the web, but all of the links are about getting and installing *drivers*. I don't need a driver, I need a userland program. With

Hello, I could not yet create combined graph in R. To avoid misunderstands, three examples (originally created in Quattro pro) have been attached. At first, I don't know how to create graph composed of bars and areas in the same picture as it is shown in the balance graph (h2plc02.gif). I am sendind the original data table from that I need make the same charts. First column (julian day)

I have the code below and it works fine if I print the xyplot but if I take the print out, then I just get a blank pdf. The same holds if I just send the plot to the console without the print ( I get nothing ). My question is whether this is always the case with xyplot or is there something wrong with my settings ? I am on linux ( redhat ) and using R.2.5.0. Thanks. load("stocks.dat")

Ok, before I definetly give up, and throw the laptop out of the window, or fill my data.frame manually, I'll ask for some help.

Dear useRs, by a circular diagram representation I mean what you will get by entering this at your R promt: pie(1:5) Nice to have R as a lingua franca :-) The folowing quote is from page 360 in this very interesting paper: @article{SpenceI2005, title = {No Humble Pie: The Origins and Usage of a Statistical Chart}, author = {Spence, I.}, journal = {Journal of Educational and

Inspired by colouring the dots of box-whisker plots I am trying to also fill the boxes (rectangles) with different colours. This seems not to work as I expected. Looking at the help page of panel.bwplot it says: 'fill - color to fill the boxplot'. Obviously it is only intended to fill all boxes with only one colour? Nevertheless the following example shows, that 'fill' from

Hi I'm trying to convert a column of strings (nominal types) to a set of boolean / binary / logical values. For example, in the column there is red, blue, green and yellow. There are 100 rows and each has a colour. I want to convert the column to 4 columns: red, blue, green,yellow and then either 1 or 0 put in the relevant row. Thanks -- View this message in context:

R-experts, I have fitted many different lines. The fast-tau estimator (yellow line) seems strange to me?because this yellow line is not at all in agreement with the other lines (reverse slope, I mean the yellow line has a positive slope and the other ones have negative slope). Is there something wrong in my R code ? Is it because the Y variable is 1 vector and should be a matrix ? Here is the
