[R] GPL and adds-on
I'm wondering is it in accordance with the law, taking into account GNU GPL on which R is based, that SPSS have adds-on module that allow you to do a analysis in R. I mean commercial software use R. I guess that nobody can create R-GUI (e.g. in JAVA) on commercial rules (licensing, pricing, selling with close source code).

[R] Cochran-Armitage
Hello, Which package allows to use Cochrana-Armitage trend test? I tried to search for but I found only package coin in which there is no explicit function.

[R] Extraction from an output
Hello, Would you tell my how to extract a result from a test - it's justified because I need to run this test many times. Here is an example from authors' test: > library("coin") > lungtumor <- data.frame(dose = rep(c(0, 1, 2), c(40, 50, 48)), tumor = > c(rep(c(0, 1), c(38, 2)), rep(c(0, 1), c(43, 7)), rep(c(0, 1), c(33, 15 > ca.test<-independence_test(tumor ~ dose, data = lungtumor, teststat = "quad") > ca.test Asymptotic General Independence Test data: tumor by dose chi-squared = 10.6381, df = 1, p-value = 0.001108 How to use ca.test and extract p-value and chi-squared.

[R] ARIMA and sig. tests
Why in arima output there is no significance tests of estimated parameters as in regression models? I know that I have s.e. and I could build these test by myself but are there any reasonable reasons?
