vector: Vector

In Rexamine/DataStructures: Useful Data Structures and Algorithms

Description

Vectors are sequence containers representing arrays that can change in size.

Usage

## S3 method for class 'Vector'
as.list(vec)

vector_create(n = 0L)

vector_empty(vec)

vector_size(vec)

vector_front(vec)

vector_back(vec)

vector_push_back(vec, obj)

vector_pop_back(vec)

vector_at(vec, i)

vector_set_at(vec, i, obj)

## S3 method for class 'Vector'
print(vec, ...)

## S3 method for class 'Vector'
format(vec, ...)

## S3 method for class 'Vector'
vec[i]

## S3 replacement method for class 'Vector'
vec[i] <- value

vector_at(vec, i) <- value

Arguments

vec	a vector object
n	vector size
obj	an R object
i	position in the vector
...	other arguments passed to or from other methods
value	object to set

Details

as.list.Vector converts a given vector object to an R list.

vector_create creates a new vector.

vector_empty determines if a given stack is empty or not.

vector_size returns a size of vector.

vector_front returns the first object of a given vector.

vector_back returns the last object of a given vector.

vector_push_back pushes a given object at the end of the vector.

vector_pop_back removes the last element in the vector, effectively reducing the container size by one.

vector_at returns an object at position i in the vector.

vector_set_at sets an object obj at position i in the vector.

print.Vector prints the contents of the vector (coerced to a list object) on the console.

format.Vector pretty-prints the contents of the vector (coerced to a list object) on the console.

[.Vector returns an object at position i in the vector.

[<-.Vector sets an object value at position i in the vector.

vector_at<- sets an object value at position i in the vector.

Value

as.list.Vector returns an R list object.

vector_create returns a new, empty vector.

vector_empty returns a single logical value.

vector_size returns a single integer value.

vector_front returns a single RObject value or throws an error if a vector is empty.

vector_back returns a single RObject value or throws an error if a vector is empty.

vector_push_back does not return anything interesting.

vector_pop_back does not return anything interesting. Throws an error if a vector is empty.

vector_at returns a single RObject value.

vector_set_at does not return anything interesting.

print.Vector returns the vector coerced to a list, invisibly.

format.Vector returns the character representation of the objects in the vector.

[.Vector returns a single R object.

[<-.Vector returns a modified vector

vector_at<- returns a modified vector
