Uncompress a raw GZIP stream
Usage
inflate(buffer, pos = 1L, size = NULL)
Arguments
- buffer
Raw vector, containing the data to uncompress.
- pos
Start position of data to uncompress in buffer.
- size
Uncompressed size estimate, or NULL. If not given, or too
small, the output buffer is resized multiple times.
Value
Named list with three entries:
output: raw vector, the uncompressed data,
bytes_read: number of bytes used from buffer,
bytes_written: number of bytes written to the output buffer.
See also
base::memDecompress() does the same with type = "gzip",
but it does not tell you the number of bytes read from the input.
Examples
data_gz <- deflate(charToRaw("Hello world!"))
inflate(data_gz$output)
#> $output
#> [1] 48 65 6c 6c 6f 20 77 6f 72 6c 64 21

#> $bytes_read
#> [1] 24
