relative_gti: Relative GTI Plot

Description

Calculate and plot the relative growth to index (GTI) over time

Usage

relative_gti(
  data = data,
  time = time,
  date_format = c("%d/%m/%Y"),
  name = theatre,
  val = emissions,
  gti_by = c("default", "month", "year")
)

Value

A ggplot2 object showing the relative GTI (Growth to Index) over time.

Arguments

data

The data frame containing the data.

time

The variable representing the time dimension.

date_format

The date format for the time variable (optional, default: c("%d/%m/%Y")).

name

The variable representing the grouping variable.

val

The variable representing the value.

gti_by

The grouping type for calculating the GTI ("default", "month", "year").

Examples

# Example dataset
emission_data <- data.frame(
  theatre = c("Theatre A", "Theatre A", "Theatre B", "Theatre B", "Theatre A", "Theatre B"),
  emissions = c(200, 250, 150, 180, 300, 220),
  date = c("01/01/2023", "01/02/2023", "01/01/2023", "01/02/2023", "01/03/2023", "01/03/2023")
  )
  
# Using the relative_gti function
relative_gti_plot <- relative_gti(
  data = emission_data,
  time = date,
  date_format = "%d/%m/%Y",  # Date format used in the dataset
  name = theatre,
  val = emissions,
  gti_by = "default"  # Calculating based on default time period
)

# Plot the relative GTI
print(relative_gti_plot)
