An option for how to handle errors returned by the API.
It is not sufficient to make the project a longitudinal project. The
project must satisfy one of two conditions: 1) have at least two arms and
one event defined; or 2) have one arm and at least two events defined. If
neither of these conditions are satisfied, the API will return a message
ERROR: You cannot export arms for classic projects, an
error message that isn't as descriptive of the nature of the problem as
we might like.
Returns a data frame with six columns
event_name The desciptive name of the event.
arm_num The arm number in which the event occurs.
day_offset The days offset from the first event.
offset_min The minimum offset value.
offset_max The maximium offset value.
unique_event_name A unique event identifying name.
This function allows you to export the events for a project
NOTE: this only works for longitudinal projects.
