R: Extract or replace parts of MCMC objects

mcmc.subset {coda} | R Documentation

## Extract or replace parts of MCMC objects

### Description

These are methods for subsetting `mcmc` objects. You can select iterations using the first dimension and variables using the second dimension. Selecting iterations will return a vector or matrix, not an `mcmc` object. If you want to do row-subsetting of an `mcmc` object and preserve its dimensions, use the `window` function.

Subsetting applied to an `mcmc.list` object will simultaneously affect all the parallel chains in the object.

### Usage

    ## S3 method for class 'mcmc'
    x[i,j, drop=missing(i)]
    ## S3 method for class 'mcmc.list'
    x[i,j, drop=TRUE]

### Arguments

`x` | An `mcmc` object
`i` | Row to extract
`j` | Column to extract
`drop` | if `TRUE`, the redundant dimensions are dropped
