What's the feature?
I know it's not any R package role to educate the users in statistics, but I noticed this misconception so many times, so maybe it's worth adding just a little note? I mean that in R Welch modification of the (pooled) t statistic with Satterthwaite df is the default one. I saw people confused why there's a discrepancy between SAS and R, as in SAS the pooled t is the default one (both pooled and Satterthwaite are reported by the PROC, but people often take just the first part).
