If my sample size is small is there a particular switch option that I need to use with t.test so that it calculates the t ratio correctly? 

Here is a dummy example?

á =0.05

Mean pain reduction for A =27; B =31 and SD are SDA=9 SDB=12

drgA.p<-rnorm(5,27,9); 

drgB.p<-rnorm(5,31,12)

t.test(drgA.p,drgB.p) # what do I need to give as additional parameter here?

 

I can do it manually but was looking for a switch option that I need to specify for  t.test. 

 

Thanks ../Murli
