summary.randportBurSt {PortfolioProbe} | R Documentation

## View Characteristics of Random Portfolios

### Description

The summary method counts the number of portfolios of each size, and the number of times each asset appears.

### Usage

    summary.randportBurSt(object)
    print.randportBurSt(x, ...)

### Arguments

`object` | an object of class `randportBurSt` as created by `random.portfolio` or `random.portfolio.utility`.
`x` | an object of class `randportBurSt` as created by `random.portfolio` or `random.portfolio.utility`.
`...` | additional arguments to `print` may be given.

### Value

the summary method returns a list with the following components:

`port.size` | a vector whose names give sizes of portfolios, and whose values give the number of portfolios of that size.
`count.assets` | a vector stating the number of occurrences of each asset.

the print method returns its input invisibly.

### Side Effects

the print method prints the object, including its attributes. It does, however, only print a few elements of the seed attribute, and does not print the `funevals`, `version` or `checkinput` attributes.

### Details

These are methods of `summary` and `print` for objects of class `"randportBurSt"`.
