rv (version 2.0.0)

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

Details

NOTE. x will NOT be automatically coerced into an rv object. 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.) must be constants, but this may change in the future.
