MoveApps
Github repository: github.com/movestore/link-r-python
This repository contains the code for both Apps that link R and Python (R to Python and Python to R). These Apps are special as they run two programming languages, thus allowing to link R Apps and Python Apps. They work with move2 on the R side and MovingPandas TrajectoryCollection on the Python side.
Both Apps create out of the input data one .csv file meta.csv. It contains transfers information about timezone and data projection between the two languages. The two csv files will then be used in the receiving language to create the proper data object.
R to Python: This App reads as input move2_loc in R, there transfers the data to csv files (see above), reads the information from those files into Python and creates a MovingPandas TrajectoryCollection as output. This output can then be used as input in Python Apps (of that IO type).
As far as we know, currently in a MovingPandas TrajectoryCollection a timezone can not be specified for the timestamps. It only works with timestamps without timezone information. The output data of this App (the MovingPandas TrajectoryCollection) will therefore contain
timestamps_tz which are timestamps containing the timezone information from the original input data (coming from R) and timestamps_utc which are the timestamps transformed into UTC (without explicit timestamp information).Python to R: This App reads as input a MovingPandas TrajectoryCollection in Python, there transfers the data to csv files (see above), reads the information from those files into R and creates a move2_loc as output. This output can then be used as input in R Apps (of that IO type).
Empty MovingPandas TrajectoryCollections will be transferred to a NULL object. An appropriate error will be shown in any following R App. Null objects from the R world will cause an error in the R to Python App.
