R: Subset of time series from the M Competitions

subset.Mcomp

R Documentation

Subset of time series from the M Competitions

Description

subset.Mcomp returns a subset of the time series data from the M Competitions. Subsets can be for specific periods, or specific types of data or both.

Usage

## S3 method for class 'Mcomp'
subset(x, cond1, cond2, ...)

Arguments

`x`	M-competition data or a subset of M-competition data
`cond1`	Type or period of the data. Type is a character variable and period could be character or numeric.
`cond2`	Optional second condition specifying type or period of the data, depending on `cond1`. If `cond1` denotes type then `cond2` would denote period, but if `cond1` denotes period then `cond2` would denote type.
`...`	Other arguments.

Details

Possible values for cond1 and cond2 denoting period are 1, 4, 12, "yearly", "quarterly", "monthly" and "other".

If cond1 or cond2 equals 111, then the 111 series used in the extended comparisons in the 1982 M-competition are selected.

Possible values for cond1 and cond2 denoting type are "macro", "micro", "industry", "finance", "demographic", "allother", "macro1", "macro2", "micro1", "micro2", "micro3". These correspond to the descriptions used in the competitions. See the references for details.

Partial matching used for both conditions.

Value

An object of class Mcomp consisting of the selected series.
