LArray 0.30 released

[Gaëtan de Menten]

Hello all,

We are pleased to announce that version 0.30 of LArray is now available.

The complete description of changes including examples can be found at: http://larray.readthedocs.io/en/stable/changes.html#version-0-30

The highlights of this release include:

• set_options() and get_options() functions to respectively set and get options for displaying arrays as strings
• read_stata() and LArray.to_stata() to read arrays from and write arrays to Stata .dta files
• LArray.keys(), LArray.values() and LArray.items() methods to respectively loop on an array labels, values or (key, value) pairs
• LArray.isin()to check whether each value of an array is contained in a list (or array) of values
• LArray.unique()to compute unique values (or sub-arrays) for an array, optionally along axes
• LArray.apply()to apply a python function to all values of an array or to all its sub-arrays along some axes and return the result
• LArray.apply_map()to apply a transformation mapping (dict) to array values
• LArray.reverse()to reverse one or several axes of an array
• LArray.roll()to roll the cells of an array n-times to the right along an axis
• improved speed of read_hdf() function when reading a stored LArray object dumped with the current and future versions of larray. To benefit for this, you must read your data and save it again using this version of larray!
• LArray.set_labels() can now take functions (such as str.upper or str.lower) to transform axes labels
• simpler “pattern language” in Axis.matching() and Group.matching()
• stack() can now stack along several axes at once
• updated the Working With Sessions section of the tutorial
• many other improvements and bug fixes

As always, any feedback is very welcome, preferably on the larray-users mailing list: larray...@googlegroups.com (you need to register to be able to post).

 

Due to a small bug we discovered after making the packages, this release needs to be installed via a "Command Prompt" window (right-click on the "Windows" icon and choose "Command Prompt"):

 

    conda install larrayenv=0.30

 

The "Update LArray" link in the "LArray" menu of the Windows start menu will NOT WORK !
