gplyr

Creating a structure in GISDK similar to data frames in R, with methods that mimic dplyr and tidyr packages.

Unit testing

A basic set of unit tests is maintained in the macro "test". At least one for each method. If adding functionality, a unit test must be created to validate the code. These unit tests will be run before accepting any pull requests.

Creation

Create a data frame object in GISDK code with the following code

df = CreateObject("df")

By default, the data frame is created empty, and one of the input methods below adds data.
