Class "indirectExternalVector", class for indirect vector subset of an externalVector object.

Description

Objects from this class store an object of class "externalVector" and a vector subscript for that object and behaves as if this is an object created by applying that subscript.

Objects from the Class

Objects can be created by calls of the form as("indirectExternalVector", vec) where vec is an object of class "externalVector".

Slots

actual:

Object of class "externalVector", the actual object of which this is a subset

index:

Object of class "vectorIndex", the vector subscript to get the subset.

Extends

Class "externalVector", directly.

Methods

e1 op e2

For any arithmetic or comparison operation op this returns the result of the operation. Either (or both) of e1 and e2 are of class "indirectExternalVector".

Complex(z)

Return the result of an operation in the Complex group generic.

Math(x)

Return the result of an operation in the Math group generic.

log(x)

Return natural logarithm of x.

log(x, base)

Return logarithm of x with base base.

x[i, j, ..., drop=FALSE]

Extract a subset of x according to the given subscripts.

x[i, j, ...] <- value

Subassign of x by value according to the given subscripts. This assigns to the correct elements of x@actual.

as.Rvector(x)

Coerce x to a basic R vector with same names, dimension and dimnames (if any of these are present in x).

as.vector(x, mode)

Return an R basic vector with mode mode.

as.matrix

Return a matrix of appropriate mode

.

length(x)

Return the length of x.

length(x) <- value

Set the length of x to value.

dim(x)

Return the dimension of x.

dim(x) <- value

Set the dimension of x to value.

dimnames(x)

Return the dimnames of x.

dimnames(x) <- value

Set the dimnames of x to value.

getExternalStorage(x)

Return the storage slot of associated with x@actual.

is.finite(x)

Return a vector of logicals with same length as x indicating if an element of x is finite.

is.infinite(x)

Return a vector of logicals with same length as x indicating if an element of x is infinite.

is.na(x)

Return a vector of logicals with same length as x indicating if an element of x is NA.

is.nan(x)

Return a vector of logicals with same length as x indicating if an element of x is NaN.

setNames(x, value)

Set the names of x to value without any error checking or coercion. Return the modified x.

force

return the result of force(x@actual)[x@index].

all(x, ..., na.rm)

Are all the values TRUE?

any(x, ..., na.rm)

Are any of the values TRUE?

min(x, ..., na.rm)

Minima of the values.

max(x, ..., na.rm)

Maxima of the values.

range(x, ..., na.rm)

Range of the values.

prod(x, ..., na.rm)

Product of the values.

sum(x, ..., na.rm)

Sum of the values.
