plot_heatmap: plot_heatmap

Description Usage Arguments Value Examples

Description

Graphs a heatmap of values stored in a matrix, such as produced by daily_response function.

Usage

1
2
plot_heatmap(result_daily_response, reference_window = "start",
  type = "daily")

Arguments

result_daily_response

a list with three objects as produced by daily_response function

reference_window

character string, the reference_window argument describes, how each calculation is referred. There are three different options: 'start' (default), 'end' and 'middle'. If the reference_window argument is set to 'start', then each calculation is related to the starting day of window. If the reference_window argument is set to 'middle', each calculation is related to the middle day of window calculation. If the reference_window argument is set to 'end', then each calculation is related to the ending day of window calculation. For example, if we consider correlations with window from DOY 15 to DOY 35. If reference window is set to ‘start’, then this calculation will be related to the DOY 15. If the reference window is set to ‘end’, then this calculation will be related to the DOY 35. If the reference_window is set to 'middle', then this calculation is related to DOY 25.

type

the character string describing type of analysis: daily or monthly

Value

A ggplot2 object containing the heatmap display
