read.qPCR: Read user formatted qPCR data and produce a qPCRBatch

Description Usage Arguments Details Value Author(s) See Also Examples

View source: R/readqPCRData.R

Description

Reads RT-qPCR data in format specified in the ReadqPCR vignette and uses the data to populate an object of class "qPCRBatch".

read.qPCR(filename = character(0),
          phenoData = new("AnnotatedDataFrame"),
          notes = "",
          verbose = FALSE)

Arguments

filename

file name (must be formatted as shown in vignette).

phenoData

an AnnotatedDataFrame object, a character of length one, or a data.frame.

notes

notes.

verbose

verbosity flag. If true more messages are given to the user on the processing steps

Details

Permits the user to read in qPCR Ct value data in a predefined format (more details on this format in the ReadqPCR package vignette), alongside phenotypic data and further notes about the data. If phenoData is a data.frame, it is converted to an AnnotatedDataFrame. If it is NULL then a default object of class AnnotatedDataFrame is created, whose pData is a data.frame with rownames being the names of the samples, and with one column sample with an integer index. More details on how technical replicates are handled in the ReadqPCR package vignette

Value

Object of class "qPCRBatch".
