)

Arguments

label

menu item label of the module in the teal app.

dataname

analysis data passed to the data argument of init. E.g. ADaM structured laboratory data frame ALB.

param_var

name of variable containing biomarker codes e.g. PARAMCD.

param

list of biomarkers of interest.

yaxis_var

name of variable containing biomarker results displayed on y-axis e.g. AVAL. When not provided, it defaults to choices_selected(c("AVAL", "CHG"), "AVAL").

xaxis_var

variable to categorize the x-axis. When not provided, it defaults to choices_selected("AVISITCD", "AVISITCD").

facet_var

variable to facet the plots by. When not provided, it defaults to choices_selected(c("ARM", "ACTARM"), "ARM").

trt_group

choices_selected object with available choices and pre-selected option for variable names representing treatment group e.g. ARM.

color_manual

vector of colors applied to treatment values.

shape_manual

vector of symbols applied to LOQ values.

facet_ncol

numeric value indicating number of facets per row.

loq_legend

loq legend toggle.

rotate_xlab

45 degree rotation of x-axis values.

hline_arb

numeric vector of at most 2 values identifying intercepts for arbitrary horizontal lines.

hline_arb_color

a character vector of at most length of hline_arb. naming the color for the arbitrary horizontal lines.

hline_arb_label

a character vector of at most length of hline_arb. naming the label for the arbitrary horizontal lines.

hline_vars

a character vector to name the columns that will define additional horizontal lines.

hline_vars_colors

a character vector naming the colors for the additional horizontal lines.

hline_vars_labels

a character vector naming the labels for the additional horizontal lines that will appear in the legend.

plot_height

controls plot height.

plot_width

optional, controls plot width.

font_size

font size control for title, x-axis label, y-axis label and legend.

dot_size

plot dot size.

alpha

numeric vector to define transparency of plotted points.

pre_output

(shiny.tag, optional)
with text placed before the output to put the output into context. For example a title.

post_output

(shiny.tag, optional) with text placed after the output to put the output into context. For example the shiny::helpText() elements are useful.

Value

an module object
