Lon2Index: Obtain the index of positions for a region in longitudes

Description

This auxiliary function returns the index of position of a region of longitudes in a given vector of longitudes.

Usage

Lon2Index(lon, lonmin, lonmax)

Value

the index of positions of all values inside the region in the vector lon.

Arguments

lon

vector of longitudes values.

lonmin

a numeric value indicating the minimum longitude of the region (understand as the left marging of the region).

lonmax

a numeric value indicating the maximum longitude of the region (understand as the right mariging of the region).

Examples

lon <- 1 : 360
pos <- Lon2Index(lon, lonmin = -20, lonmax = 20)
lon[pos]
pos <- Lon2Index(lon, lonmin = 340, lonmax = 20)
lon[pos]
lon <- -180 : 180
pos <- Lon2Index(lon, lonmin = -20, lonmax = 20)
lon[pos]
pos <- Lon2Index(lon, lonmin = 340, lonmax = 20)
lon[pos]
