The main changes from version0.9.15 the previous CRAN release, are:
Revise the code for all solar-position-related calculations to improve computation speed when arguments are vectors. The returned values and their high precision remains the same as in recent versions, but when called with long vectors of times or dates, performance is orders of magnitude faster than in earlier versions. Revise documentation. Fix some minor bugs in example sensor data.
Rename color() method to color_of() to avoid name clashes. Define a function color() maintain backwards compatibility. Define colour_of() to provide synonym for British spelling.
Changes from the previous CRAN release 0.2.14 are:
Add stat_fit_tidy() which makes it possible to add labels or equations with estimated parameter values embedded. To build complex equations familiarity with R’s expressions as described under plotmath will be of help. This statistic supports all the types of models supported by package ‘broom’, which is used internally.
