memuse (version 4.0-0)

Constructor: memuse Constructor

Description

Constructor for objects of class memuse.

Usage

mu(size, unit = "best", prefix = "IEC", names = "short")
# S4 method for ANY
mu(size, unit = "best", prefix = "IEC", names = "short")
# S4 method for `NULL`
mu(size, unit = "best", prefix = "IEC",
  names = "short")
# S4 method for numeric
mu(size, unit = "best", prefix = "IEC",
  names = "short")
# S4 method for object_size
mu(size, unit = "best", prefix = "IEC",
  names = "short")
# S4 method for missing
mu(size, unit = "best", prefix = "IEC",
  names = "short")
memuse(size, unit = "best", prefix = "IEC", names = "short")
# S4 method for ANY
memuse(size, unit = "best", prefix = "IEC",
  names = "short")
# S4 method for `NULL`
memuse(size, unit = "best", prefix = "IEC",
  names = "short")
# S4 method for missing
memuse(size, unit = "best", prefix = "IEC",
  names = "short")
# S4 method for numeric
memuse(size = size, unit = "best", prefix = "IEC",
  names = "short")
# S4 method for object_size
memuse(size, unit = "best", prefix = "IEC",
  names = "short")

Arguments

size

numeric; indicates the unit-multiple number of bytes used by the object.

unit

string; the unit of storage, such as "MiB" or "MB", depending on prefix. Case is ignored.

prefix

string; the unit prefix, namely IEC or SI. Case is ignored.

names

string; control for whether the unit names should be printed out or their abbreviation should be used. Options are "long" and "short", respectively. Case is ignored.

Value

Returns a memuse class object.

Details

For numeric objects, if the length is 1, then its value is used as the number of bytes. Otherwise, the object's memory usage in R is taken for the size parameter.

Examples

# NOT RUN {
### The value passed as 'size' is the number of bytes
x <- memuse(100, unit="kb")
x

y <- memuse(100, unit="kb", prefix="SI")
y

### Use the memory usage of object 'size'
memuse(rnorm(1e4))
# }
# NOT RUN {
# }
