I have two groups of patients (improved or not improved) named x and y group respectively after being treated with 5 different drugs
X<-c(43,52,25,48,57) and Y<-c(237,198,245,212,233) when I run chisq.test(cbind(x,y)) I get a p value of <0.0024 but if I run chisq.test(x,y) I get a p value of 0.22 not significant at 5% what is the difference between the two thanks bragadeesh ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
