I used chisq.test(read.table("C:/Users/Maggy/Downloads/dust.asc", header=TRUE))
and got this Pearson's Chi-squared test data: read.table("C:/Users/Maggy/Downloads/dust.asc", header = TRUE) X-squared = 5226.164, df = 3735, p-value < 2.2e-16 and I think it should be right for the whole set, but that's not what I need, because I only have to use it for "cbr" and "smoking" -- View this message in context: http://r.789695.n4.nabble.com/need-help-for-chi-squared-test-tp3177925p3178052.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
