Assign fossil occurrences to latitudinal bins

Source: R/bin_lat.R
bin_lat.Rd

A function to assign fossil occurrences to user-specified latitudinal bins.

Usage

bin_lat(occdf, bins, lat = "lat", boundary = FALSE)

Arguments

occdf

dataframe. A dataframe of the fossil occurrences you wish to bin. This dataframe should contain a column with the latitudinal coordinates of occurrence data.

bins

dataframe. A dataframe of the bins that you wish to allocate fossil occurrences to, such as that returned by lat_bins(). This dataframe must contain at least the following named columns: "bin", "max" and "min".

lat

character. The name of the column you wish to be treated as the input latitude (e.g. "lat" or "p_lat"). This column should contain numerical values. Defaults to "lat".

boundary

logical. If TRUE, occurrences falling on the boundaries of latitudinal bins will be duplicated and assigned to both bins. If FALSE, occurrences will be binned into the upper bin only (i.e. highest row number).

Value

A dataframe of the original input occdf with appended columns containing respective latitudinal bin information.

Examples

# Load occurrence data
occdf <- tetrapods
# Generate latitudinal bins
bins <- lat_bins_degrees(size = 10)
# Bin data
occdf <- bin_lat(occdf = occdf, bins = bins, lat = "lat")
#> Presence of occurrences falling on boundaries detected. 
#> Occurrences assigned to upper bin.
