mcmc.subset: 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
