Hello,
I am trying to see whether there has been a significant difference in whether
people experienced damages from wildlife in two different years. I therefore
have two columns:
year 1:
yes
no
no
no
yes
yes
no
year 2:
no
yes
no
yes
I wanted to do a chisq.test, but if I enter it this way:
chisq.test(year1, year2)
I get the error saying the columns are two different lengths. So then I tried
doing:
damages<-matrix(c(3,4, 2,2), ncol=2, dimnames=list(answer=c("yes", "no"),
year=c("year1", year2)))
chisq.test(damages)
Does that make sense? Should I maybe be doing a different test instead?
Any help would be appreciated, thank you.
Agnese
