Calculate marks for track and field combined events

Description

marks() calculates marks for track and field combined events competitions.

Usage

marks(scores, gender, combined_event = NULL, seconds = FALSE)

Arguments

scores

a numeric vector of track and field scores

gender

gender of athlete; either "male" or "female"

combined_event

an optional character string indicating the combined events competition. For gender = "male", the options are "decathlon"/"outdoor decathlon", "outdoor pentathlon", "heptathlon"/"indoor heptathlon", and "indoor pentathlon". For gender = "female", the options are "heptathlon"/"outdoor heptathlon", "decathlon"/"outdoor decathlon", and "pentathlon"/"indoor pentathlon". If combined_event = NULL, the elements of scores must be named.

  • For gender = "male", the allowed names for the elements of scores are `100m`, LJ, SP, HJ, `400m`, `110mH`, DT, PV, JT, `1500m`, `200m`, `60m`, `60mH`, and `1000m`.

  • For gender = "female", the allowed names are `100m`, LJ, SP, HJ, `400m`, `100mH`, DT, PV, JT, `1500m`, `200m`, `60mH`, and `800m`.

seconds

a logical; if TRUE, will return all track event marks in seconds

Details

marks() performs the opposite action of scores(): you give it the scores you want to obtain, and it gives you the marks you need to achieve those scores. For track events, marks() returns the slowest time needed to achieve the input score. Similarly, for jumping and throwing events, marks() returns the shortest distance necessary to achieve the input score.

For some events, when a score is given to marks(), the score returned may be different from the one input because some scores are not actually possible (due to rounding of track and field marks). When an impossible score is given to marks(), the function will return the closest higher score that corresponds to a mark.

Value

A list of class "combined_events" (or "combined_events_null" if combined_event = NULL) with the following fields:

results

if called with non-NULL combined_event, a data frame with columns for the specified combined event containing the names of those events, mark for the resulting marks based on the input scores, and score based on the input scores. The last row of the data frame gives the total score for the specified combined events competition. If combined_event = NULL, a data frame with columns event, mark, and score.

marks

the vector of marks based on the input scores for the specified combined event. If not all scores were supplied to marks(), then there will be NA values for those events with missing scores. If combined_event = NULL, the vector of marks.

scores

the vector of scores for the specified combined event. If not all scores were supplied to marks(), then there will be NA values for those events with missing scores. If combined_event = NULL, the vector of scores.

score_total

if called with non-NULL combined_event, an integer representing the overall score for the specified combined events competition

call

the matched call

Examples

# Men's heptathlon
marks(scores = rep(800, 7),
      gender = "male", combined_event = "heptathlon")

# Women's pentathlon
marks(scores = c(`60mH` = 981, HJ = 875, SP = 799, LJ = 956, `800m` = 1000),
      "female", "pentathlon")

# Men's events
marks(scores = c(LJ = 790, LJ = 810, HJ = 850, HJ = 900, PV = 900, PV = 915),
      "male")
