You probably do not distinct between columns of data frame and row names 
of data frame. From what you told us it is not clear which one you want to 
keep

if row names use

as.data.frame(as.matrix(t, row.names = names(t)))

if you want to keep column

as.data.frame(t)

shall suffice. 

Row names is not a data frame column.
