QualFreqPlot {ReQON} | R Documentation |
Plots the relative frequency distribution of quality scores before and after recalibration.
QualFreqPlot(QualFreqBefore, QualFreqAfter, before_col = "blue", after_col = "red", inc_legend = TRUE, xlabel = "Quality Score", ylabel = "Relative Frequency", main_title = "Frequency Distributions of Quality Scores")
QualFreqBefore |
vector of relative frequencies of quality scores before recalibration. The first element in the vector corresponds to a quality score of zero. |
QualFreqAfter |
vector of relative frequencies of quality scores after recalibration. The first element in the vector corresponds to a quality score of zero. |
before_col |
color of line plotting the frequency before recalibration. Default = "blue". |
after_col |
color of line plotting the frequency after recalibration. Default = "red". |
inc_legend |
option for including a legend. Default = TRUE. |
xlabel |
x-axis label. Default = "Quality Score". |
ylabel |
y-axis label. Default = "Relative Frequency". |
main_title |
title. Default = "Frequency Distributions of Quality Scores". |
QualFreqPlot plots the relative frequency distribution of quality scores before and after recalibration. If the input vectors are $QualFreqBefore and $QualFreqAfter from ReQON output, this function will create the top right diagnostic plot that is output from ReQON.
For more details and interpretation, see the vignette by: browseVignettes("ReQON").
