In landscapemetrics: Landscape Metrics for Categorical Map Patterns

Show correlation

Description

Show correlation

Usage

show_correlation(
  data,
  method = "pearson",
  diag = TRUE,
  labels = FALSE,
  vjust = 0,
  text_size = 15
)

Arguments

data	Tibble with results of as returned by the landscapemetrics package.
method	Type of correlation. See link{cor} for details.
diag	If FALSE, values on the diagonal will be NA and not plotted.
labels	If TRUE, the correlation value will be added as text.
vjust	Will be passed on to ggplot2 as vertical justification of x-axis text.
text_size	Text size of the plot.

Details

The functions calculates the correlation between all metrics. In order to calculate correlations, for the landscape level more than one landscape needs to be present. All input must be structured as returned by the landscapemetrics package.

For all metrics based on distances or areas please make sure your data is valid using check_landscape.

Value

ggplot

Examples

landscape <- terra::rast(landscapemetrics::landscape)

metrics <- calculate_lsm(landscape, what = c("patch", "class"))
show_correlation(data = metrics, method = "pearson")

## Not run: 
metrics <- calculate_lsm(landscape, what = c("patch", "class"))
correlations <- calculate_correlation(metrics)
show_correlation(data = correlations, method = "pearson")

## End(Not run)
