zlib (version 1.0.3)

compress: Single-step compression of raw data

Description

Compresses the provided raw data in a single step.

Usage

compress(
  data,
  level = -1,
  method = zlib$DEFLATED,
  wbits = zlib$MAX_WBITS,
  memLevel = zlib$DEF_MEM_LEVEL,
  strategy = zlib$Z_DEFAULT_STRATEGY,
  zdict = NULL
)

Value

A raw vector containing the compressed data.

Arguments

data

Raw data to be compressed.

level

Compression level, default is -1.

method

Compression method, default is zlib$DEFLATED.

wbits

Window bits, default is zlib$MAX_WBITS.

memLevel

Memory level, default is zlib$DEF_MEM_LEVEL.

strategy

Compression strategy, default is zlib$Z_DEFAULT_STRATEGY.

zdict

Optional predefined compression dictionary as a raw vector.

Details

The compress function simplifies the compression process by encapsulating the creation of a compression object, compressing the data, and flushing the buffer all within a single call. This is particularly useful for scenarios where the user wants to quickly compress data without dealing with the intricacies of compression objects and buffer management. The function leverages the compressobj function to handle the underlying compression mechanics.

Examples

compressed_data <- compress(charToRaw("some data"))
