show_correlation function

Show correlation

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.

Returns

ggplot

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.

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)
