Class "bamHeader": Textual representation of header section of BAM files.

Description

bamHeader manages textual representation of data contained in the header section of BAM-files. The binary representation (from which new BAM-files can be created) is encapsulated in class 'bamHeader'. Both types can be converted into each other.

Objects from the Class

Objects can be created by calls of the form hl<-new("bamHeader").
