formatToHierarchicalData {clinDataReview}

Format data to a hierarchical data, in the format as required by the plotly sunburst and treemap.

Usage

formatToHierarchicalData(data, vars, valueVar)

Arguments

data

Data.frame with data.

vars

Character vector with variables of data containing the groups. If multiple, they should be specified in hierarchical order (from parent to child node).

• 'varID': String with column of output containing ID of specific element.
  This is a combination from the specified vars, or 'Overall' for the grand total.

• 'varParent': String with column of output containing ID of the parent element

• 'varLabel': String with column of output containing the label to display.
  This is usually the name of the child element.
