Generate HTML Tooltip Text

Usage

generate_tooltip_text(data, labels_df, tooltip_vars, type)

Arguments

data: A data.frame with the source data.
labels_df: A data.frame used by get_label() to find variable labels.
tooltip_vars: A character vector of column names to include in the tooltip.
type: A character string specifying the label type for get_label().

Value

A character vector of formatted HTML tooltip strings.

Details

Creates a character vector of HTML tooltips for each row of a data frame, suitable for use with ggplotly. The output vector of this function should be added to original plotting data as a column, which then can be used as tooltip argument in the plotting function.

Examples

# Sample data
my_data <- data.frame(
  USUBJID = c("Subject-01", "Subject-02"),
  DOSE = c(100, 200),
  RESPONSE = c(5.4, 8.1)
  )

my_labels <- data.frame(
  Dataset = "ADPC",
  Variable = "USUBJID",
  Label = "Unique Subject ID"
  ) # Dummy labels object

vars_to_show <- c("USUBJID", "DOSE", "RESPONSE")

# Generate the tooltip text vector
tooltips <- generate_tooltip_text(my_data, my_labels, vars_to_show, "ADPC")
my_data$tooltip <- tooltips
