readContiguousValues.AbstractFileArray {R.huge}R Documentation

Reads sets of contiguous values in the file array

Description

Reads sets of contiguous values in the file array. A set of contiguous values are values that are connecting without a break. It is much faster to read contiguous sequences at once than read each value separately.

Usage

## S3 method for class 'AbstractFileArray':
readContiguousValues(this, indices, lengths=1, mode=getStorageMode(this), size=getBytesPerCell(this), offset=getDataOffset(this), ..., .checkArgs=TRUE)

Arguments

indices A numeric vector of start (first) indices in each of the contiguous sets.
length A numeric vector specifying the length of each of the contiguous sets.
mode The storage mode to read.
size The number of bytes each values allocates on file.
offset The file offset to the first value on file.
... Not used.
.checkArgs If TRUE, arguments are validated, otherwise not.

Value

Returns a numeric vector.
