R Documentation

Forecast Variables available in each model.

Description

Variables available in each model. The grepVar function is a wrapper around grep to search for variables.

Usage

grepVar(x, service, day = Sys.Date() - 15, complete = FALSE)

Arguments

`x`	character string to be matched in the `description` column of the corresponding `vars*` file.
`service`	Character, to choose from 'meteogalicia', 'gfs', 'nam', and 'rap'
`day`	Date. Services change the variables availability over time.
`complete`	Logical, if `FALSE` (default) only the `name` column is returned. If `TRUE` the three columns are provided.

Value

Each data.frame contains three columns, name, label, and description, with the information about the variables available in each service. Use the elements of the name column to choose a variable with the argument var of getRaster and getPoint.
