S3-filearray {filearray}

'S3' methods for 'FileArray'

Description

These are 'S3' methods for 'FileArray'

Usage

## S3 method for class 'FileArray'

  x[
  i,
  ...,
  drop = TRUE,
  reshape = NULL,
  strict = TRUE,
  dimnames = TRUE,
  split_dim = 0
]

## S3 replacement method for class 'FileArray'
x[i, ..., lazy = FALSE] <- value

## S3 method for class 'FileArray'
x[[i]]

## S3 method for class 'FileArray'
as.array(x, reshape = NULL, drop = FALSE, ...)

## S3 method for class 'FileArray'
dim(x)

## S3 method for class 'FileArray'
dimnames(x)

## S3 replacement method for class 'FileArray'
dimnames(x) <- value

## S3 method for class 'FileArray'
length(x)

## S3 method for class 'FileArray'
max(x, na.rm = FALSE, ...)

## S3 method for class 'FileArray'
min(x, na.rm = FALSE, ...)

## S3 method for class 'FileArray'
range(x, na.rm = FALSE, ...)

## S3 method for class 'FileArray'
sum(x, na.rm = FALSE, ...)

## S3 method for class 'FileArray'
subset(x, ..., drop = FALSE, .env = parent.frame())

Arguments

x

a file array

i, ...

index set, or passed to other methods

drop

whether to drop dimensions; see topic Extract

reshape

a new dimension to set before returning subset results; default is NULL (use default dimensions)

strict

whether to allow indices to exceed bound; currently only accept TRUE

dimnames

whether to preserve dimnames

split_dim

internally used; split dimension and calculate indices to manually speed up the subset; value ranged from 0 to size of dimension minus one.

lazy

whether to lazy-evaluate the method, only works when assigning arrays with logical array index

value

value to substitute or set

na.rm

whether to remove NA values during the calculation

.env

environment to evaluate formula when evaluating subset margin indices.
