Arguments

x	an object of class semnar. See add_presentation().
group	according to what should the semnars be selected on the map? Available options are "none", "year", "month", "presenter", "event", "country", "city" (default), "year+country".
title	character string for the title of the map. Default is NA, which produces no title.
title_position	the position of the title on the map, if title is not NA. Available options are "bottomleft" (default), "bottomright", "topleft", "topright".
provider	the provider of tiles for the base map. See leaflet::addProviderTiles(). Default is "OpenStreetMap.Mapnik".
interval	Should the start and end times in each popup be displayed as an interval (TRUE; default) or in two separate lines (FALSE)?
date_format	In what format should the dates be displayed? Available options are "dmy", "mdy", "ydm", "ymd", where "y" stands for year, "m" stands for month, and "d" stands for day.
shorten_url	Should the URL links in "object$link" be shortened? Default is FALSE.
service	service to use for shortening URLs. Current options are "Is.gd" (default) and "V.gd". See shorten_url().
width	As in leaflet::leaflet(). Default is NULL.
height	As in leaflet::leaflet(). Default is NULL.
show_event_url	Should the event or talk/seminar URL ("link" argument in add_presentation()) be printed in the popups (TRUE), or the event name ("event" argument in add_presentation()) become a hyperlink pointing to the event or talk/seminar URL (FALSE; default).
opacity	As in leaflet::markerOptions(). Default is 0.2.
past_year_colour	Colour to be used for past year's presentations. Default is "#ef3b2c". See Details.
this_year_colour	Colour to be used for this year's presentations. Default is "#737373". See Details.
...	Arguments to be passed to other methods. Currently unused.

Value

An interactive map (opens in browser) with the locations of the events. When the locations are clicked, pup-ups appear which give access to event details. A legend with the colour-year combination is printed only if this_year_colour != past_year_colour. The current year is determined by lubridate::year(Sys.time()).
