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.
The only difference from the version released a year ago is the addition of support for an additional feature and a method: “internal trigger” and method “getLastException”, both seem to be supported by only few spectrometer types.
