semnar
provides methods for constructing and maintaining a database of
presentations in R. The presentations are either ones that the user
gives or gave or presentations at a particular event or event series. semnar
also provides methods for the interactive mapping of the presentations
using leaflet by grouping them according to country, city,
year and other presentation attributes (see ?plot.semnar).
The markers on the map come with popups providing presentation details
(title, institution, event, links to materials and events, and so
on).
You can install the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("ikosmidis/semnar")and the released version with:
install.packages("semnar")add_presentation is the main function for constructing
and maintaining a data base of presentations. For example, below I
record the details of a recent presentation I gave to the PhD students
and PostDocs at University of Warwick on workflows and task
management.
library("semnar")
YRM <- event(event = "Young Researchers' Meeting",
country = "England",
city = "Coventry",
lon = -1.560843, lat = 52.384019,
link = "https://warwick.ac.uk/fac/sci/statistics/news/yrm/",
institution = "University of Warwick",
department = "Department of Statistics",
venue = "Mathematical Sciences Building")
IK <- presenter(name = "Ioannis", surname = "Kosmidis",
affiliation = "University of Warwick",
email = "ioannis.kosmidis@warwick.ac.uk",
link = "https://ikosmidis.com")
IK_talks <- add_presentation(presenter = IK,
title = "A workflow that most probably isn't yours",
type = "presentation",
event = YRM,
room = "M1.02",
materials = "https://ikosmidis.com/files/ikosmidis_YRM_2019.pdf",
start = "29 May 2019 4pm",
end = "29 May 2019, 17:00")Here, I start by defining the event information using
event(), the presenter information using
presenter(), and then supply the resulting objects in an
add_presentation() call along with other
presentation-specific details. add_presentation also
provides arguments for supplying the same event and presenter
information (and much more; see ?add_presentation), but
using the event() and presenter() constructor
is useful when there are many presentations in the same event, and/or
many presentations by the same presenter.
IK_talks is now a structured data.frame
that also inherits from class semnar, including the
supplied presentation details.
str(IK_talks)

R package, which allows for great flexibility in the format that
dates/times are supplied.
The details in the database can be mapped using leaflet:
plot(IK_talks, group = "city",
title = "<a href='https://cran.r-project.org/package=semnar'>semnar</a> map")
See ?plot.semnar for the customization options
plot.semnar provides, and my talks page for a live version
with talks I gave in the last few years…
jsonlite can be directly used to export the semnar
databases into json files, ready to use in other software:
library("jsonlite")
