Description

Flag Occurrences those are in wrong ocean basins and are inland

Usage

ec_flag_non_region(
  direction,
  ocean,
  buffer = 50000,
  data,
  latitude = "decimalLatitude",
  longitude = "decimalLongitude"
)

Value

A new column with flagged values, 1 means bad records 0 means good record. Column name: flag_non_region

Arguments

direction,

values as "east" or "west". These values help to filter the shape files for east or west of select ocean (e.g. pacific) for both north and south hemisphere.

ocean,

values such as "pacific" or "atlantic"

buffer,

Its a certain buffer distance to consider if a data point is inland. Beyond this distance data points consider as bad data points. e.g. buffer <- 25000

data,

Data table which has latitude and longitude information

latitude

default set to "decimalLatitude"

longitude

default set to "decimalLongitude"

Examples

if (FALSE) {
direction <- "east"
buffer <- 25000
ocean <- "pacific"
data <- data.frame(
  species = "A",
  decimalLongitude = c(-120, -78, -110, -60, -75, -130, -10, 5),
  decimalLatitude = c(20, 34, 30, 10, 40, 25, 15, 35)
)
data$flag_non_region <- ec_flag_non_region(
  direction,
  ocean,
  buffer = 50000,
  data
)
