Arguments
- label
menu item label of the module in the teal app.
- dataname
analysis data passed to the data argument of teal init. E.g. ADaM structured laboratory data frame ADLB.
- param_var
name of variable containing biomarker codes e.g. PARAMCD.
- param
biomarker selected.
- param_var_label
single name of variable in analysis data that includes parameter labels.
- idvar
name of unique subject id variable.
- xaxis_var
single name of variable in analysis data that is used as x-axis in the plot for the respective goshawk function.
- yaxis_var
single name of variable in analysis data that is used as summary variable in the respective gshawk function.
- xaxis_var_level
vector that can be used to define the factor level of xaxis_var. Only use it when xaxis_var is character or factor.
- filter_var
data constraint variable.
- trt_group
choices_selected
object with available choices and pre-selected option for variable names representing treatment group e.g. ARM.- trt_group_level
vector that can be used to define factor level of trt_group.
- group_stats
control group mean or median overlay.
- man_color
string vector representing customized colors
- color_comb
name or hex value for combined treatment color.
- xtick
numeric vector to define the tick values of x-axis when x variable is numeric. Default value is waive().
- xlabel
vector with same length of xtick to define the label of x-axis tick values. Default value is waive().
- rotate_xlab
boolean value indicating whether to rotate x-axis labels
- facet_ncol
numeric value indicating number of facets per row.
- plot_height
controls plot height.
- plot_width
optional, controls plot width.
- font_size
control font size for title, x-axis, y-axis and legend font.
- 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.
- 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 theshiny::helpText()
elements are useful.
