call_erra: Error Analysis for 1D Electrophoresis Gels

Description

This function analyzes fingerprint replicate data. Replicates are repeated measurements of the same sample in one or more gels, which allows the reproducibility of the measurement to be ascertained.

Usage

call_erra(rep.file, work_dir = ".", dnum = 1, sd = 4, delete = FALSE)

Arguments

rep.file

is the full name and path of the replicate file

work_dir

is where the datasets should be stored

dnum

is the file number

sd

is the standard deviation needed to calculate all things, Salamon et al. (1998) suggested a value of 4 for sd

delete

logical value indicating if you want to delete any pre-existing acm.par files. Default is FALSE

Value

the parameter filed called acm.par, needed by call_acm. This file contains information on about the measurement error present in the data.
