bumbl (development version)

bumbl 1.0.4

In autoplot.bumbldf() the first argument has been re-named from x to object for consistency with other autoplot() methods.
bumbl now uses the lifecycle package to manage function lifecycle

Added a new dataset, test_df, containing simulated data used for package testing.
Added a tau_optim_maxit argument to bumbl() that is passed to optim(). Mostly for getting consistent convergence failures in tests, but possibly useful to end user.

First "stable" release
fixed bug with duplicate column names
added note in documentation clarifying that bumbl() assumes a switchpoint, and doesn't test for one.

bumbl was peer-reviewed through rOpenSci
changed bumbl() to use glm() instead of lm() to fit models. Uses log-link gaussian error by default.
family argument in bumbl() now passed directly to glm() unless "negbin", in which case MASS::glm.nb() is used.
Added ... argument to bumbl() to pass additional arguments (e.g. offset) to glm() or glm.nb()
Added a keep.model argument to bumbl() which outputs a list-column with the models fit to each colony.
added change in mass to bombus data
removed bumbl_plot() and instead added a plot() method for base R plots and an autoplot() method for ggplot2
now requires tidyr version 1.0.0 or greater
optimization of switchpoint now done with optim(). Removed tau argument to bumbl() and brkpt() as it is no longer applicable (may be added again in the future, but with different behavior).

bumbl() no longer errors when a single colony produces an error
added a vignette
updated bombus data to include cumulative floral resources
fixed major bug (issue #12) that cause bumbl() to return the incorrect colony IDs
added bubml_plot() for checking the output of bumbl()

Added a NEWS.md file to track changes to the package.
This is the first minimally functioning version of bumbl. More features to come. Feedback welcome.
