Arguments

x	list of two data frames, one containing the number of missing values by sample, and the other containing missing values by molecule
omicsData	object of class 'pepData', 'proData', 'metabData', 'lipidData', nmrData', or 'seqData', created by as.pepData, as.proData, as.metabData, as.lipidData, as.nmrData, or as.seqData, respectively.
plot_type	character string specifying which type of plot to produce. The two options are 'bar' or 'scatter'.
nonmissing	logical value. When FALSE, plots missing values. When TRUE, plots non-missing values.
proportion	logical value. When TRUE, plots the proportion of missing (or non-missing if nonmissing is TRUE) to the total number of values. Only works with a plot type of 'bar'.
order_by	A character string specifying a column in f_data by which to order the samples. Specifying "Group" will use the "Group" column of the object's group_DF attribute to order the samples. Only works with a plot type of 'bar'.
color_by	A character string specifying a column in f_data by which to color the bars or the points depending on the plot_type. Specifying "Group" will use the "Group" column of the object's group_DF attribute to color the samples. Only works with a plot type of 'bar'.
interactive	logical value. If TRUE produces an interactive plot.
x_lab_bar	character string used for the x-axis label for the bar plot
x_lab_scatter	character string used for the x-axis label for the scatter plot
y_lab_bar	character string used for the y-axis label for the bar plot
y_lab_scatter	character string used for the y-axis label for the scatter plot
x_lab_size	integer value indicating the font size for the x-axis. The default is 11.
y_lab_size	integer value indicating the font size for the y-axis. The default is 11.
x_lab_angle	integer value indicating the angle of x-axis labels.
title_lab_bar	character string used for the plot title when plot_type is 'bar'.
title_lab_scatter	character string used for the plot title when plot_type is 'scatter'.
title_lab_size	integer value indicating the font size of the plot title. The default is 14.
legend_lab_bar	character string specifying the legend title when creating a bar plot.
legend_lab_scatter	character string specifying the legend title when creating a scatter plot.
legend_position	character string specifying the position of the legend. Can be one of "right", "left", "top", or "bottom". The default is "right".
point_size	An integer specifying the size of the points. The default is 2.
text_size	An integer specifying the size of the text (number of missing values by sample) within the bar plot. The default is 3.
bar_width	An integer indicating the width of the bars in the bar plot. The default is 0.8.
bw_theme	logical value. If TRUE uses the ggplot2 black and white theme.
palette	character string indicating the name of the RColorBrewer palette to use. For a list of available options see the details section in RColorBrewer.
display_count	logical value. Indicates whether the missing value counts by sample will be displayed on the bar plot. The default is TRUE.
coordinate_flip	logical value. Indicates whether the x and y axes will be flipped. The default is FALSE.
use_VizSampNames	logical value. Indicates whether to use custom sample names. The default is FALSE.
...	further arguments passed to or from other methods.

Details

This function takes in an object of class naRes and creates either a bar or scatter plot of missing values. When plot_type = 'bar', a sample name by missing values count bar chart is returned. When plot_type = 'scatter' a mean intensity vs number of missing values (per molecule) scatter plot is returned. Note: If the omicsData object has had group_designation applied to it, the points in the plot will be colored by group.

Value

ggplot2 plot object if interactive is FALSE, or plotly plot object if interactive is TRUE

Examples

library(pmartRdata)
mylipid <- group_designation(omicsData = lipid_neg_object, main_effects = "Virus")
result <- missingval_result(omicsData = mylipid)
plot(result, omicsData = mylipid, plot_type = "bar",
     x_lab_angle = 50, order_by = "Virus", color_by = "Virus")
plot(result, omicsData = mylipid, plot_type = "scatter",
     x_lab_angle = 50, color_by = "Virus")

result <- missingval_result(omicsData = rnaseq_object)
plot(result, omicsData = rnaseq_object, plot_type = "bar")
