Additional validation checks on a DataVolley file

Source: R/validation.R
validate_dv.Rd

This function is automatically run as part of dv_read if extra_validation is greater than zero. The current validation messages/checks are:

  • message "The total of the [home|visiting] team scores in the match result summary (x$meta$result) does not match the total number of points recorded for the [home|visiting] team in the plays data"

  • message "Players xxx and yyy have the same player ID": player IDs should be unique, and so duplicated IDs will be flagged here

  • message "The listed player is not on court in this rotation": the player making the action is not part of the current rotation. Libero players are ignored for this check

  • message "Back-row player made an attack from a front-row zone": an attack starting from zones 2-4 was made by a player in the back row of the current rotation

  • message "Front-row player made an attack from a back-row zone (legal, but possibly a scouting error)": an attack starting from zones 1,5-9 was made by a player in the front row of the current rotation

  • message "Quick attack by non-middle player"

  • message "Block by a back-row player"

  • message "Winning serve not coded as an ace"

  • message "Non-winning serve was coded as an ace"

  • message "Serving player not in position 1"

  • message "Player designated as libero was recorded making a [serve|attack|block]"

  • message "Attack (which was blocked) does not have number of blockers recorded"

  • message "Attack (which was followed by a block) has 'No block' recorded for number of players"

  • message "Repeated row with same skill and evaluation_code for the same player"

  • message "Consecutive actions by the same player"

  • message "Point awarded to incorrect team following error (or \"error\" evaluation incorrect)"

  • message "Point awarded to incorrect team (or [winning play] evaluation incorrect)"

  • message "Scores do not follow proper sequence": one or both team scores change by more than one point at a time

  • message "Visiting/Home team rotation has changed incorrectly"

  • message "Player lineup did not change after substitution: was the sub recorded incorrectly?"

  • message "Player lineup conflicts with recorded substitution: was the sub recorded incorrectly?"

  • message "Reception type does not match serve type": the type of reception (e.g. "Jump-float serve reception" does not match the serve type (e.g. "Jump-float serve")

  • message "Reception start zone does not match serve start zone"

  • message "Reception end zone does not match serve end zone"

  • message "Reception end sub-zone does not match serve end sub-zone"

  • message "Attack type ([type]) does not match set type ([type])": the type of attack (e.g. "Head ball attack") does not match the set type (e.g. "High ball set")

  • message "Block type ([type]) does not match attack type ([type])": the type of block (e.g. "Head ball block") does not match the attack type (e.g. "High ball attack")

Usage

validate_dv(x, validation_level = 2, options = list(), file_type)

Arguments

x

datavolley: datavolley object as returned by dv_read

validation_level

numeric: how strictly to check? If 0, perform no checking; if 1, only identify major errors; if 2, also return any issues that are likely to lead to misinterpretation of data; if 3, return all issues (including minor issues such as those that might have resulted from selective post-processing of compound codes)

options

list: named list of options that control optional validation behaviour. Valid entries are:

  • setter_tip_codes character: vector of attack codes that represent setter tips (or other attacks that a back-row player can validly make from a front-row position). If you code setter tips as attacks, and don't want such attacks to be flagged as an error when made by a back-row player in a front-row zone, enter the setter tip attack codes here. e.g. options=list(setter_tip_codes=c("PP","XY"))

file_type

string: "indoor" or "beach". If not provided, will be taken from the x$file_meta$file_format entry

Value

data.frame with columns message (the validation message), file_line_number (the corresponding line number in the DataVolley file), video_time, and file_line (the actual line from the DataVolley file).

Examples

if (FALSE) {
  x <- dv_read(dv_example_file(), insert_technical_timeouts = FALSE)
  xv <- validate_dv(x)

  ## specifying "PP" as the setter tip code
  ## front-row attacks (using this code) by a back-row player won't be flagged as errors
  xv <- validate_dv(x, options = list(setter_tip_codes = c("PP"))) 
}
