[R] Help: chisq.test

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
