Make standalone hepExplorer html widget

Convience mapping of render_widget for hepExplorer.

hepExplorer(df = safetyData::adam_adlbc, mapping = NULL, ...)

Arguments

df	data frame containing lab data used to render for hepExplorer. Default is safetyData::adam_adlbc.
mapping	named list with the current data mappings. See details for default mapping.
...	additional options to be added to mapping. Will overwrite mapping.

Details

The data and mapping should match the specs described in the hepExplorer javascript library. Items passed in ... are added to mapping, and then the list is converted to json via jsonlite::toJSON(mapping, auto_unbox=TRUE, null="null").

The default mapping shown below is designed to work with data in the CDISC ADaM format (like safetydata::adam_adlbc).

mapping <- list(
           measure_col = "PARAM", 
           measure_values = list(
               ALT = "Alanine Aminotransferase (U/L)", 
               AST = "Aspartate Aminotransferase (U/L)", 
               TB = "Bilirubin (umol/L)",
               ALP = "Alkaline Phosphatase (U/L)"
           ), 
           id_col = "USUBJID", 
           value_col = "AVAL", 
           normal_col_low = "A1LO",                    
           normal_col_high = "A1HI", 
           studyday_col = "ADY", 
           visit_col = "VISIT",
           visitn_col = "VISITNUM"
       )                  

Parameters that are not included in the default mapping can be accessed via ...; Key options and defaults for safetyData::adam_adlbc shown below:

• filters: list of columns to be included as data filters (e.g. `filters=c("SEX","AGEGR1")``)

• group_cols: list of columns used to define grouping and set point color (e.g. `filters=c("SEX","AGEGR1")``)

• x_options and y_options - specify which labs can be used for x and y axis dropdowns. By default, all options are included on x-axis, but only Bilirubin is shown on y-axis. To allow an interactive y-axis, use y_options="all".

• baseline - flag defining the baseline visit for each participant. baseline must be provided to enable the mDish view on the hep-explorer chart. Define as a list with value_col and values (e.g. baseline=list(value_col="ABLFL",values="Y"))

• title and warningText - Strings used to define the header text shown above the filters.

For more options see the full specs in the javascript library.

Examples

if (FALSE) {
# Render widget with defaults
hepExplorer() 

# Add age group to default
hepExplorer(group_cols=c("SEX","AGEGR1")) 

# Enable interactive y-axis
hepExplorer(y_options='all') 

# Use custom mapping for SDTM data
hepExplorer(
    df=safetyData::sdtm_lb,
    measure_col = "LBTEST", 
    measure_values = list(
        ALT = "Alanine Aminotransferase", 
        AST = "Aspartate Aminotransferase", 
        TB = "Bilirubin",
        ALP = "Alkaline Phosphatase"
    ), 
    id_col = "USUBJID", 
    value_col = "LBSTRESN", 
    normal_col_low = "LBORNRLO",                    
    normal_col_high = "LBORNRHI", 
    studyday_col = "LBDY", 
    visit_col = "VISIT",
    visitn_col = "VISITNUM"
)
