formula1_points_systems(top=11)A hyper2 object that gives a likelihood function
Object formula1 is a hyper2 object that gives a likelihood
function for the strengths of the competitors of the 2017 Formula One
(Drivers') World Championship. Object F1_table_2017 is an order table: a
data frame with rows being drivers, columns being venues, and entries
being places. Thus looking at the first row, first column we see that
Hamilton placed second in Austria.
The package uses files like inst/formula1_2017.txt as primary
sources. These are generally copied from wikipedia, converted into
tab-separated clean seven bit ascii, and tidied up a little. I have
removed diacritics from names, so we see “Raikkonen”,
“Perez”, etc. Also where distinct drivers with the same
surname compete, I have indicated this, e.g. schumacher_R is Ralf
Schumacher, schumacher_M is Michael, and schumacher_Mick
is Mick; the underscore device means that quoting should not be needed
in R idiom. I have not been entirely consistent here, with Bruno Senna
appearing as “Senna_B” and Nelson Piquet Junior appearing
as “PiquetJ” [on the grounds that in these cases the
fathers, being more eminent, should be the primary eponym] although this might
change in the future.
Object F1_table_2017 is simply the first 20 columns of
read.table(inst/formula1_2017.txt) and object
F1_points_2017 is column 21. The likelihood function
formula1 is ordertable2supp(F1_table_2017). The datasets
in the package are derived from text files in the inst/ directory
(e.g. formula1_2017.txt) by script file
inst/f1points_Omaker.R. Executing this script creates files like
formula1_results_2017.rda.
The text files can be converted directly into ranktable objects
and support functions as follows:
a <- read.table("formula1_2022.txt",header=TRUE)
a <- a[,seq_len(ncol(a)-1)] # strips out the points column
wikitable_to_ranktable(a)
ordertable2supp(a)Function formula1_points_system() gives various possible points
systems for the winner, second, third, etc, placing drivers.
The constructors' championship is discussed at constructor.Rd.
There is a large amount of documentation in the inst/ directory
in the form of Rmd files.
