add.sig.thr: Add the significance thresholds to an existing QTL plot.

Description Usage Arguments Value Author(s) See Also Examples

View source: R/add.sig.thr.R

Description

Given a set of thresholds, add the autosomal and X chromosome thresholds to an existing QTL plot. The user may call plot() and then this function, but plot.doqtl contains a 'sig.thr' argument and will call this automatically. The threhsolds can be obtained from get.sig.thr

Usage

1
  add.sig.thr(sig.thr, sig.col = "red", chrsum)

Arguments

sig.thr

Numeric matrix or a numeric vector with the significance thredholds, typically obtained from get.sig.thr. If sig.thr is a matrix, then it must have 2 columns names 'A' and 'X' and each significance threshold is in one row.

sig.col

Numeric vector containing the plotting colors for each threshold. The length of sig.col must equal nrow(sig.thr).

chrsum

Numeric vector with the cumulative sum of the chromosome lengths. Must be named with chromosome names.

Value

Plots autosomal and X chromosome thresholds on a QTL plot. Behavior on other plots is undetermined.
