Usage

tm_g_gh_scatterplot(
  label,
  dataname,
  param_var,
  param,
  xaxis_var,
  yaxis_var,
  trt_group,
  color_manual = NULL,
  shape_manual = NULL,
  facet_ncol = 2,
  trt_facet = FALSE,
  reg_line = FALSE,
  rotate_xlab = FALSE,
  hline = NULL,
  vline = NULL,
  plot_height = c(500, 200, 2000),
  plot_width = NULL,
  font_size = c(12, 8, 20),
  dot_size = c(1, 1, 12),
  reg_text_size = c(3, 3, 10),
  pre_output = NULL,
  post_output = NULL
)

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 ADLB.
param_var: name of variable containing biomarker codes e.g. PARAMCD.
param: biomarker selected.
xaxis_var: name of variable containing biomarker results displayed on x-axis e.g. BASE.
yaxis_var: name of variable containing biomarker results displayed on y-axis e.g. AVAL.
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.
trt_facet: facet by treatment group trt_group.
reg_line: include regression line and annotations for slope and coefficient in visualization. Use with facet TRUE.
rotate_xlab: 45 degree rotation of x-axis values.
hline: y-axis value to position of horizontal line.
vline: x-axis value to position a vertical line.
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.
reg_text_size: font size control for regression line annotations.
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.
