YAXArrayBase.jl

YAXArrayBase

A package defining an interface to work with named dimension that might have values associated with them.

Suported backends:

• DimensionalData
• AxisArrays
• AxisIndices
• YAXArrays
• NamedDims
• ArchGDAL raster types

Usage

Conversion between axis array types

using AxisArrays, DimensionalData, YAXArrayBase
a = AxisArray(rand(10,2), row = 11:20, col=["One","Two"])

2-dimensional AxisArray{Float64,2,...} with axes:
    :row, 11:20
    :col, ["One", "Two"]
And data, a 10×2 Array{Float64,2}:
 0.0467821  0.116614
 0.944797   0.827642
 0.593597   0.883222
 0.365977   0.368537
 0.486696   0.591154
 0.622487   0.572724
 0.805211   0.0480554
 0.570345   0.627014
 0.687585   0.936112
 0.149575   0.237352

yaxconvert(DimensionalArray,a)

DimensionalArray with dimensions:
Dim row (type Dim): 11:20
Dim col (type Dim): String[One, Two]
and data: 10×2 Array{Float64,2}
0.0467821  0.116614
0.944797   0.827642
0.593597   0.883222
0.365977   0.368537
0.486696   0.591154
0.622487   0.572724
0.805211   0.0480554
0.570345   0.627014
0.687585   0.936112
0.149575   0.237352

The axis array interface

This is done through the axis array interface, the most important functions are dimvals and dimnames:

dimnames(a)

(:row, :col)

dimvals(a,1)

11:20

Look at src/axisinterface to get a full description of the interface.

Zarr backend

The Zarr dataset backend is enabled by loading ZarrCore. ZarrCore on its own only handles local stores and writes uncompressed data. Load the subpackages you need, or simply using Zarr to get all of them:

• ZarrHTTP, ZarrS3, ZarrGCS for remote stores
• ZarrBlosc, ZarrZlib, ZarrZstd for compression (ZarrBlosc makes Blosc the default compressor)
• ZarrZip for reading .zarr.zip files
