Hi Gang, Peter,

I still have troubles.

Welcome to afex. Important notes:

Due to popular demand, afex doesn't change the contrasts globally anymore.
To set contrasts globally to contr.sum run set_sum_contrasts().
To set contrasts globally to the default (treatment) contrasts run set_default_contrasts().

All afex functions are unaffected by global contrasts and use contr.sum as long as check.contr = TRUE (which is the default).

Error in `$<-.data.frame`(`*tmp*`, "Subj", value = integer(0)) :

i have attached the scripts after adding the wsVars.

Thanks.
