Subject: need help with chisq
I am very new to R. I have some data from a CVS stored in vdata with 4
columns labeled:
X08, Y08, X09, Y09.
I have created two new "columns" like so:
Z08 <- (vdata$X08-vdata$Y08)
Z09 <- (vdata$X09-vdata$Y09)
I would like to use chisq.test for each "row" and output the p-value
for each in a stored variable. I don't know how to do it. Can you
help?
so far I have done it for one row (but I want it done automatically
for all my data):
chidata=rbind(c(vdata$Y08[1],Z08[1]),c(vdata$Y09[1],Z09[1]))
results <- chisq.test(chidata)
results$p.value
I tried removing the [1] and the c() but that didn't work... Any
ideas?
THANKS!
