Replace NA Values in Indicator Objects

This function takes an indicator_map or indicator_ts object and replaces all NA values in the diversity_val column with zeros. This is useful when NA values represent areas or years with no data that should be treated as zero for mapping or analysis purposes. Only use it when zero is a meaningful value for the indicator: for indicators such as evenness, NA means the value is undefined (e.g. fewer than two species), not zero.

Usage

replace_na(x)

Arguments

x

An indicator_map or indicator_ts object containing a diversity_val column with NA values to replace.

Value

The input indicator object with NA values in diversity_val replaced by zero. Stops with an error if there are no NA values.

Examples

# Observed richness is NA in cells without occurrences, where zero species
# were observed
or_map_filled <- replace_na(example_indicator_map1)
#> Replaced 477 NA values with zeroes.
