'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.
