Extract.rv: Extract or Replace Parts of a Random Vector

Description

Bracket slice and assignment methods adapted for random vectors and arrays.

Value

• A random variable (an rv object).

synopsis

## S3 method for class 'rv': [(x, \dots , drop = TRUE) ## S3 method for class 'rv': [<-(x, \dots , drop = TRUE) ## S3 method for class 'rv': [[<-(x, \dots , drop = TRUE)

Details

x may also be a regular vector that is automatically coerced into an rv object if the compatibility flag has been set to 1 by rvcompatibility(1) (this is the default). value may be an rv object or a regular numeric object.

Extracting rv objects works the same way as extracting components of a numerical vector or array. The return value is always an object of class 'rv'. Type ?Extract for details.

Note: the index arguments (i, j, etc.) may be themselves random variables, however they will be coerced into integers, as one would expect.
