sub-.pField: Extract or replace parts of a pField object

In EarthSystemDiagnostics/pfields: An R Package to Analyse Gridded Field Data

Description

Method for extracting or replacing a subset of a "pField" object.

Usage

## S3 method for class 'pField'
x[p1, p2, ...]

Arguments

x	a "pField" object.
p1	possible row indices for the subset: x[p1, ].
p2	possible column indices for the subset: x[, p2].
...	further arguments passed on to the generic method "["; currently not needed.

Details

For subsetting, the class of the returned object depends on the specified indices:

x[p1, ]

a "pField" object.

x[, p2]

a "pTs" object if p2 is of length 1 (single site) or if the subset is not compatible with a "pField" object (i.e. the subset sites cover more than one latitude, but, for each, do not cover the full range of longitudes).

x[p1, p2]

same as before for the time subset p1.

x[p1]

a numeric vector of length length(p1) where the time and lat-lon information are lost with a warning.

x[] or x[,]

the original object x.

Value

the original object with the replaced subset x[p1, p2], or the subset x[p1, p2]. For the latter, depending on the provided indices, this can be an object of class "pField", an object of class "pTs", or simply a numeric vector; see details.
