Re: [R] suggestion for paired t-tests

Hi Jack, Maybe this helps. # make some data set.seed(123) condition - factor(rep(c(a,b), each = 5)) score - rnorm(10); lg - data.frame(condition, score) # Carry out commands a - subset(lg,condition==a)[score] b - subset(lg,condition==b)[score] t.test(a,b,paired=TRUE) #Error in

There's a funny inconsistency in how t.test handles paired=T or paired=F. If x and y parameters are lists, paired=F works, but paired=T doesn't. lg=read.csv(my.csv) a = subset(lg, condition==a)[score] b = subset(lg, condition==b)[score] t.test(a,b) t.test(a,b, paired=TRUE) Error in
