Two very similar commands produce different headers in latex() from Hmisc. The question is: how to get rid of the excessive header that is repeated right in the first page of longtable?
latex(data.frame(1:10), caption="Title", longtable=TRUE, rowname=NULL)

latex(data.frame(1:10, 10:1), caption="Title", longtable=TRUE, rowname=NULL)
