Dear List I am looking for a script that will calculate the Box M test to test the homogeneity of the variance/covariance matrix between two matrices. If anyone could send me the script I would appreciate it. I am aware of the scepticism about this test, where due to extreme sensitivity a p value of 0.01 is recommended. Despite this however Box's M test is the established

Is there a function available in R that implements Mojena's Upper Tail Rule or that draws a Mojena plot? I would also like to find a function that implements Duda and Hart's stopping rule.

Hi, I'm trying to get a list of addresses from http://tatts.com/racing/outletsearch based on a list of postcodes (zip codes) and states. For example, I'm looking for State = 'Northern Territory' and Postcode = '0800'. The list I'm working off is about 500 long so I was hoping to find a way to script this in R. I regularly us readLines and the XML library to scrape

Sorry if this is a FAQ but I have tried searching the web and both samba3 books but I can't find the answer.

Ideally I would like an XP client to appear in both domains and the user to get different profiles depending on which domain they

Hi All, I have a data frame with three columns i.e., pc, lat, lon. The pc column is populated with list of postcodes, and I want to execute R command that can get me the lat and lon for the every item in the pc column and populate the respective lat and lon columns. Is there any package that could be used? Any help will be really appreciated. Many Thanks and Kind Regards -- Muhammad

Thanks. I was "believing" an Excel import of the file - as you say, a re-import into R still has 333 columns. I shall look elsewhere for the cause of the mysterious truncation.

Hi, I''m pretty new to ruby and rails, so apologies if this has been covered before (I couldn''t find a thread on it). I want to retrieve a count of records held in the DB for every distinct value of an attribute. E.g. given a class Address with a postcode field, I would like to retrieve an array of ValueCount objects. The ValueCount object would hold the value retrieved from

Hi Stuart, I often use this small function standardize <- function(x) ( x - mean(x, na.rm=T) ) / sqrt(var(x, na.rm=T)) to standardize variables. You should be able to use this to do what you want by splitting the data frame into sections based on the factor level, using standardize() to create a new variable in each section, then paste the data frame back together. Something like: #

In the sample program below I have a form of 6 text fields, in a scrolling window, followed by a row of function buttons.
