gg_injprev_polar {injurytools}

Plot polar area diagrams representing players' prevalence

Description

Plot the proportions of available and injured players in the cohort, on a monthly or season basis, by a polar area diagram. Further information on the type of injury may be specified so that the injured players proportions are disaggregated and reported according to this variable.

Usage

gg_injprev_polar(
  injd,
  by = c("monthly", "season"),
  var_type_injury = NULL,
  title = "Polar area diagram\ninjured and available (healthy) players"
)

Arguments

injd

Prepared data, an injd object.

by

Character, one of "monthly" or "season", specifying the periodicity according to which to calculate the proportions of available and injured players/athletes.

var_type_injury

Character specifying the name of the column on the basis of which to classify the injuries and calculate proportions of the injured players. It should refer to a (categorical) variable that describes the "type of injury". Defaults to NULL.

title

Text for the main title.

Value

A ggplot object (to which optionally more layers can be added).

Examples

df_exposures <- prepare_exp(raw_df_exposures, player = "player_name",
                            date = "year", time_expo = "minutes_played")
df_injuries  <- prepare_inj(raw_df_injuries, player = "player_name",
                            date_injured = "from", date_recovered = "until")
injd         <- prepare_all(data_exposures = df_exposures,
                            data_injuries  = df_injuries,
                            exp_unit = "matches_minutes")
