[Blosc](https://www.blosc.org/) is a blocking, shuffling and lossless compression
algorithm. It is often used to compress n-dimensional structured
array data. It is applied (among others) in the geo-spatial
[zarr](https://zarr.dev/) file format. This package ports BLOSC compressors and
decompressors to R.

## Installation

Install latest developmental version from R-Universe:

``` r
install.packages("blosc", repos = c('https://pepijn-devries.r-universe.dev', 'https://cloud.r-project.org'))
```

MacOS users may first need to install system requirements before installing the package using:

```r
source("https://mac.R-project.org/bin/install.R")
install.libs("blosc")
```

## Example

The blosc package can be used to compress `raw` data, but also vectors of
other data types. The example below shows how data from the volcano matrix
can be compressed with blosc.

```{r example1}
library(blosc)

volcano_compressed <-
  blosc_compress(volcano, typesize = 2L, dtype = "
