Hello All: I am trying to replicate the results of an example found in Alan Agresti's "Categorical Data Analysis" on pages 267-269. The example is one of a 2 x 2 cross-classification table of ordinal counts: job satisfaction and income. I am able to get Agresti's results for the independence model (G^2 = 12.03 with df = 9) assuming as he does that the data is nominal, but

...a model of the type y~x1+x2+x3+x4+x5, where y is: y [1] 17 17 35 69 69 173 173 17 17 73 17 35 69 35 35 52 As you see the differences are no too small. Where is the problem? Is only a numerical stability problem?

Hi all! my apologies if this is too elementary: I upgraded to 1.5.0. I copied my library folder on version 1.4.1 to the library folder on 1.5.0. When I try to upload a package via the menu I get this: Error in sort(.packages(all.available = TRUE)) : 1 argument passed to "sort" which requires 2. do I have to copy any other file from the previous version?. Thanks in

Hi, I'm having problems while working with large data sets with R 1.5.1 in windows 2000. Given a integer matrix size of 30 columns and 15000 rows my function should return a boolean matrix size of about 5000 rows and 15000 columns. First of all I tried to run this function on computer with 256 MB of RAM. I increased memory limit of R with memory.limit() up to 512 MB. I was inspecting

Hi R developers and users: How do "mod" and "integer division" work with negative integers on R? I mean why you obtain different results if you work on C or anywhere else and in R? I see R guarantees that `x == (x %% y) + y * ( x %/% y )', but it looks rare the individual (x %% y) and y * ( x %/% y ) results when you use negative integers, because is contradictory
