I have a problem when one of the vectors in a list needs to be
replicated to have the appropriate length, and an attribute is present.
> w <- list(a=1, b=2:3)
> as.data.frame(w)
a b
1 1 2
2 1 3
> attr(w$a,'label') <- 'foo'
> as.data.frame(w)
Error in data.frame(a = 1, b = c(2, 3), check.names = TRUE) :
arguments imply differing number of rows: 1, 2
I usually use the Hmisc label function to make a variable of class
'labelled' and define as.data.frame.labelled as as.data.frame.vector,
but that also fails here. Any help appreciated. -Frank
