RCMIP5 (version 1.0)

filterDimensions: Filter dimensions, limiting to arbitrary lon/lat/Z/time

Description

We frequently want to filter CMIP5 data according to some predetermined criteria: only high-latitude cells, for example, or certain years, months, Zs, etc. This function provides convenient one-stop service for such filtering.

Usage

filterDimensions(x, lons = NULL, lats = NULL, Zs = NULL, years = NULL,
  months = NULL, verbose = FALSE)

Arguments

x

A cmip5data object

lons

numeric vector. Longitudes to filter

lats

numeric vector. Latitudes to filter

Zs

numeric vector. Z values to filter

years

numeric vector

months

numeric vector

verbose

logical. Print info as we go?

Value

• The filtered cmip5data object.

Examples

d <- cmip5data(1970:2014)   # sample data
filterDimensions(d, years=1980:1985)
filterDimensions(d, months=6:8)  # summer
filterDimensions(d, lats=d$lat[abs(d$lat)<20])  # the tropics
