This function generates a Styled Layer Descriptor (SLD) XML for styling network metric layer based on quantile breaks colors.

Usage

sld_get_style(breaks, colors, metric)

Arguments

breaks

A numeric vector containing quantile breaks.

colors

A character vector of colors generated based on quantile breaks.

metric

The name of the selected metric.

Value

A character string containing the SLD XML for styling data visualization.

Examples

#> 	Is the server running locally and accepting connections on that socket?
