view-summarization-methods: Summarize views on an XInteger or XDouble object

In XVector: Foundation of external vector representation and manipulation in Bioconductor

Description

The viewMins, viewMaxs, viewSums, and viewMeans methods described here calculate respectively the minima, maxima, sums, and means of the views in an XIntegerViews or XDoubleViews object.

Usage

## "viewMins" methods:
## -------------------

## S4 method for signature 'XIntegerViews'
viewMins(x, na.rm=FALSE)

## S4 method for signature 'XDoubleViews'
viewMins(x, na.rm=FALSE)


## "viewMaxs" methods:
## -------------------

## S4 method for signature 'XIntegerViews'
viewMaxs(x, na.rm=FALSE)

## S4 method for signature 'XDoubleViews'
viewMaxs(x, na.rm=FALSE)


## "viewSums" methods:
## -------------------

## S4 method for signature 'XIntegerViews'
viewSums(x, na.rm=FALSE)

## S4 method for signature 'XDoubleViews'
viewSums(x, na.rm=FALSE)


## "viewMeans" methods:
## --------------------

## S4 method for signature 'XIntegerViews'
viewMeans(x, na.rm=FALSE)

## S4 method for signature 'XDoubleViews'
viewMeans(x, na.rm=FALSE)


## "viewWhichMins" methods:
## ------------------------

## S4 method for signature 'XIntegerViews'
viewWhichMins(x, na.rm=FALSE)

## S4 method for signature 'XDoubleViews'
viewWhichMins(x, na.rm=FALSE)


## "viewWhichMaxs" methods:
## ------------------------

## S4 method for signature 'XIntegerViews'
viewWhichMaxs(x, na.rm=FALSE)

## S4 method for signature 'XDoubleViews'
viewWhichMaxs(x, na.rm=FALSE)

Arguments

x	An XIntegerViews or XDoubleViews object.
na.rm	Logical indicating whether or not to include missing values in the results.

Value

A numeric vector of the length of x.

Note

For convenience, methods for min, max, sum, mean, which.min and which.max are provided as wrappers around the corresponding view* functions (which might be deprecated at some point).
