# swephR v0.3.0

This afternoon swephR version 0.3.0 made it unto CRAN and is now propagating to the mirrors.

The goal of swephR is to provide an R interface to the Swiss Ephemeris (SE), a high precision ephemeris based upon the DE431 ephemeris from NASA’s JPL. It covers the time range 13201 BCE to 17191 CE.

This new version comes with two important changes. First, Victor has finished the laborious task of making all functions from SE’s C API available to R. Second, I have added a docker image that is automatically build on each push to master and checks for UBSAN errors using the wch1/r-debug image.

The latter change was triggered by the UBSAN errors present in v0.2.0 and my fear that more problems like this might be contained within the SE code base. This is particularly important once we add more test cases to the package. Currently only about 50% of the code is exposed to automatic testing. Increasing the coverage ratio might reveal more UBSAN issues. Hopefully, they will be caught before submission to CRAN this time.
