getItems: Get Items

Description

Extract items of a given (sub-)dimension of a MAgPIE-object

Usage

getItems(x, dim = NULL, split = FALSE, full = FALSE)
getItems(x, dim, full = NULL, maindim = NULL, raw = FALSE) <- value

Value

items of the requested dimension in the MAgPIE-object. If split=TRUE and applied to a main dimension (1,2,3) a list of items for each sub-dimension.

Arguments

x

MAgPIE object

dim

Dimension for which the items should be returned. Either number or name of dimension or a vector of these. See dimCode for more details.

split

Boolean which determines whether a main dimension should be split in subdimensions. Only applicable to main dimensions (1,2,3) and ignored for all other.

full

if TRUE dimension names are returned as they are (including repetitions), if FALSE only the dimension elements (unique list of entries) are returned.

maindim

main dimension the data should be added to (does not need to be set if dim exists in the data. Should be set if dim might not exist, or if dim might potentially exist in a different main dimension than the one anticipated).

raw

if set to FALSE inputs will be corrected (e.g. dots replaced by the letter "p") if necessary. If TRUE data will be written as is (risking the creation of inconsistent objects).

value

a vector with the length of the main dimension the dimnames should be replaced in / added to. If set to NULL the corresponding dimension will be removed.

Functions

• getItems(x, dim, full = NULL, maindim = NULL, raw = FALSE) <- value: set dimension names
