R: Coerce Envelope to Data Frame

as.data.frame.envelope {spatstat.core} | R Documentation

## Coerce Envelope to Data Frame

### Description

Converts an envelope object to a data frame.

### Usage

    ## S3 method for class 'envelope'
    as.data.frame(x, ..., simfuns=FALSE)

### Arguments

`x` | Envelope object (class `"envelope"`).
`...` | Ignored.
`simfuns` | Logical value indicating whether the result should include the values of the simulated functions that were used to build the envelope.

### Details

This is a method for the generic function `as.data.frame` for the class of envelopes (see `envelope`.

The result is a data frame with columns containing the values of the function argument (usually named `r`), the function estimate for the original point pattern data (`obs`), the upper and lower envelope limits (`hi` and `lo`), and possibly additional columns.

If `simfuns=TRUE`, the result also includes columns of values of the simulated functions that were used to compute the envelope. This is possible only when the envelope was computed with the argument `savefuns=TRUE` in the call to `envelope`.

### Value

A data frame.

### Examples

      E <- envelope(cells, nsim=5, savefuns=TRUE)
      tail(as.data.frame(E))
      tail(as.data.frame(E, simfuns=TRUE))
