Paired ttest using lme4

Hi Ghader,

a) tt is not set up in the correct way for a pair t-test.
b) the mixed model assumes the variances are equal, but the call to t.test specifies them to be different.

t.test(tt2[1:3,3], tt2[4:6,3], var.equal=TRUE)

is identical to lmer.

Cheers,

Jarrod

var.equal = F
