tabix_read: Read a line from a tabix_open()'ed file

Description

Read a line from a tabix_open()'ed file

Usage

tabix_read( tabfh )
tabix_readraw( tabfh )

Arguments

tabfh

Tabix file handle as returned by tabix_open

Value

A line of data from the indexed data file. tabix_read splits the line up into its fields and returns a vector. tabix_readraw returns the line as stored in the file.

Details

Instead of tabix_readraw() you can use .Call("tabix_readLine", tabfh ) to eliminate the slight overhead of using the R wrapper function.
