In pmartR: Panomics Marketplace - Quality Control and Statistical Analysis for Panomics Data

Diagnostic plot for seqData

Description

For generating statistics for 'seqData' objects

Usage

dispersion_est(
  omicsData,
  method,
  interactive = FALSE,
  x_lab = NULL,
  x_lab_size = 11,
  x_lab_angle = NULL,
  y_lab = NULL,
  y_lab_size = 11,
  title_lab = NULL,
  title_lab_size = 14,
  legend_lab = NULL,
  legend_position = "right",
  bw_theme = TRUE,
  palette = NULL,
  point_size = 0.2,
  custom_theme = NULL
)

Arguments

omicsData	seqData object used to terst dispersions
method	either "DESeq2", "edgeR", or "voom" for testing dispersion
interactive	Logical. If TRUE produces an interactive plot.
x_lab	A character string specifying the x-axis label when the metric argument is NULL. The default is NULL in which case the x-axis label will be "count".
x_lab_size	An integer value indicating the font size for the x-axis. The default is 11.
x_lab_angle	An integer value indicating the angle of x-axis labels.
y_lab	A character string specifying the y-axis label. The default is NULL in which case the y-axis label will be the metric selected for the metric argument.
y_lab_size	An integer value indicating the font size for the y-axis. The default is 11.
title_lab	A character string specifying the plot title when the metric argument is NULL.
title_lab_size	An integer value indicating the font size of the plot title. The default is 14.
legend_lab	A character string specifying the legend title.
legend_position	A character string specifying the position of the legend. Can be one of "right", "left", "top", or "bottom". The default is "right".
bw_theme	Logical. If TRUE uses the ggplot2 black and white theme.
palette	A character string indicating the name of the RColorBrewer palette to use. For a list of available options see the details section in RColorBrewer.
point_size	An integer specifying the size of the points. The default is 0.2.
custom_theme	a ggplot 'theme' object to be applied to non-interactive plots, or those converted by plotly::ggplotly().

Details

DESeq2 option requires package "survival" to be available.
