lucC_plot_frequency_events: Plot Frequency Polygon with lucC Events

In ammaciel/stilf: Land Use Change Calculus

Description

Plot frequency polygon over time

Usage

lucC_plot_frequency_events (data_tb = NULL, 
custom_palette = FALSE, RGB_color = NULL, pixel_resolution = 250, 
relabel = FALSE, original_labels = NULL, new_labels = NULL)

Arguments

data_tb	Tibble. A tibble with values longitude and latitude and other values
custom_palette	Boolean. A TRUE or FALSE value. If TRUE, user will provide its own color palette setting! Default is FALSE
RGB_color	Character. A vector with color names to map legend, for example, c("Green","Blue"). Default is setting scale_colour_hue
pixel_resolution	Numeric. Is a spatial resolution of the pixel. Default is 250 meters considering MODIS 250 m. See more at https://modis.gsfc.nasa.gov/about/specifications.php.
relabel	Boolean. A TRUE or FALSE value. If TRUE, user will provide its own legend text setting! Default is FALSE
original_labels	Character. A vector with original labels from legend text, for example, c("Forest","Pasture").
new_labels	Character. A vector with new labels to legend text, for example, c("Mature_Forest","Pasture1").

Value

Plot a frequency polygon in Y axis in square kilometers (Area km^2) = (Number of pixel *(pixel_resolution*pixel_resolution))/(1000*1000)
