Class "sampleBamFiles": Data on multiple BAM files from an experimental setting.

Description

The object contains data on location of BAM files, experimental group assignment and number of aligns per BAM file. The align-numbers are used for normalisation when alignment depth is plotted for single genes.

Objects from the Class

Objects can be created by calls of the form bs<-sampleBamFiles(object) where object is a numeric vector of length1.

Slots

bamFiles:

"character": Location of BAM files

bamIdxFiles:

"character": Location of BAM index files

nAligns:

"numeric": Total number of alignments in each BAM file.

group:

"factor": Group assignment

label

"character": Short textual identifier for each sample.

length

"integer": Vector length for bamFiles, bamIdxFiles, nAligns, group and label.

ev

"environment": Contains additional data (e.g. group table).
