[Bioc-devel] TabixFileList() constructor broken in devel

[Robert Castelo]

hi,

the 'TabixFileList()' constructor in Rsamtools seems to be broken in devel:

library(Rsamtools)
example(TabixFileList) ## which actually does not construct any 
'TabixFileList'
TabixFileList(tbx)
Error in as.vector(x, "character") :
   cannot coerce type 'environment' to vector of type 'character'

while in release this works fine:

library(Rsamtools)
example(TabixFileList) ## which actually does not construct any 
'TabixFileList'
TabixFileList(tbx)
TabixFileList of length 1
names(1): example.gtf.gz

the man page has not changed between devel and release and the current 
description of the argument 'file' supports the use of a 'TabixFile' 
instance as input:

     file: For TabixFile(), A character(1) vector to the tabix file
           path; can be remote (http://, ftp://). For ‘countTabix’, a
           character(1) or ‘TabixFile’ instance. For others, a
           ‘TabixFile’ instance.

please find below my session information for the devel run.

thanks!

robert.
