sftrack 0.5 (2020-09-13): Major update.

• Changed from ‘burst’ name to ‘group’ name. This includes changing ind_burst -> s_group (single group) and multi_burst -> c_grouping (column grouping). Verbage has also been changed in all documentation.
• Relative angle added to summary_sftrack, as well as fixing issue where absolute angle was calculating 180 from actual angle.
• ‘Active_group’ were placed back at the column level. This means that any row level group does not have an active burst, but a column collection of bursts can define which of those groupings are ‘activated’.
• Sort index returns and is an attribute of a column grouping. It is a factor that is recalculated everytime something in the data frame is changed like a subset or grouping is changed. This is to try to bring the sftrack grouping more inline with how dplyr::group_by works internally. You can access this with burst_labels (returns the factor) and burst_names (get just the levels()).
• Plotting is more streamlined in both base plot and ggplot. A step_mode has been added for sftraj so you can choose to display the individual line segments. Although the default is to calculate the merged trajectories, which is must faster.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
