clean_dup: Function to clean duplicated longitude and latitude data

In luismurao/nichetoolbox: From getting biodiversity data to evaluating species distribution models in a friendly GUI environment

Description

Clean duplicated longitude and latitude data using threshold distance which is a distance (in grades) between points to be considered duplicates.

Usage

clean_dup(data, longitude, latitude, threshold = 0)

Arguments

data	A data.frame with longitude and latitude data
longitude	A character vector of the column name of longitude.
latitude	A character vector of the column name of latitude.
threshold	A numerc value representig the distance (in grades) between coordinates to be considered as a duplicate.

Value

Returns a data.frame with coordinate data from species

Examples

# Species genus
genus <- "ambystoma"
# Species name
species <- "tigrinum"
# GBIF search
# ambystoma_tigrinum <- searh_gbif_data(genus,species,
#                                        occlim=100,
#                                        writeFile=FALSE)
# ambystoma_tigrinum_clean <- clean_dup(ambystoma_tigrinum,
#                                     longitude = "longitude",
#                                     latitude = "latitude",
#                                     threshold=0.0)
# Check the dimensions of  data
# dim(ambystoma_tigrinum)
# dim(ambystoma_tigrinum_clean)
