Extract: Extract or replace parts of a free group object

In freegroup: The Free Group

Extract or replace parts of a free group object

Description

Extract or replace subsets of free objects

Usage

## S3 method for class 'free'
x[...]
## S3 replacement method for class 'free'
x[index] <-  value

Arguments

x	Object of class free
index	elements to extract or replace
value	replacement value
...	Elements to extract

Details

These methods (should) work as expected: an object of class free is a list but standard extraction techniques should work.

Note

Extraction by NA is not implemented.

Examples

(x <- rfree(20,8,8))

x[5:6]
x[1:2]  <- -x[11:12]

x[1:5] <- keep(x[1:5],1:3)
