Flag occurrences those has bad precision

Usage

ec_flag_precision(
  data,
  latitude = "decimalLatitude",
  longitude = "decimalLongitude",
  threshold = 2
)

Arguments

data

dataframe

latitude

decimalLatitude, this a field in the data file. We prefer to use decimalLatitude as accepeted name based on TDWG standards

longitude

decimalLongitude, this a field in the data file. We prefer to use decimalLongitude as accepeted name based on TDWG standards

threshold

set on 2

Value

A column which has flagged records represents bad records based on low precision as well as rounding

Examples

data <- data.frame(
  species = "A",
  decimalLongitude = c(-120.67, -78, -110, -60, -75.5, -130.78, -10.2, 5.4),
  decimalLatitude = c(20.7, 34.6, 30.0, 10.5, 40.4, 25.66, 15.0, 35.9)
)

data$flag_cordinate_precision <- ec_flag_precision(
  data,
  latitude = "decimalLongitude",
  longitude = "decimalLatitude",
  threshold = 2
)
