[Bioc-devel] scanTabix coercion to data.frame

[Hahne, Florian]

Hi all,
I frequently get into the situation that I import data from a Tabix file
using scanTabix and get a list of character vectors which I first need to
split back into columns using strsplit, followed by some type coercion and
lapply/sapply to actually get a list of data.frames which is what I'd
really want out in the first place. I may be missing something here, but
wouldn't it be possible to ask scanTabix for a list of data.frames
directly, and maybe even providing a vector of data types to coerce into,
a la 'colClasses' in read.table? It just seems to me that these operations
could be done much more efficiently on the C level.
Thanks,
Florian
