In martingerdin/bengaltiger: bengaltiger

Description

Adds a new indicator variable to the study sample, defining what patients had the specific injury or injury pattern provided.

Arguments

study.sample	Data frame. The study sample. No default.
injury.codes	Character vector. The patterns to be used to define the specific injury or injury pattern. If any of the codes is present in any of the variables listen in injury.variables an observation will be classified as having the injury. No default.
variable.name	Character vector of length 1. The name of the variable. No default.
injury.variables	Character vector. The names of the variables with injudy data. Defaults to c("e_1_icd", "e_2_icd", "e_3_icd", "e_4_icd", "e_5_icd", "e_6_icd", "e_7_icd", "e_8_icd", "e_9_icd", "e_10_icd", "e_11_icd", "e_12_icd", "xray_1_icd", "xray_2_icd", "xray_3_icd", "xray_4_icd", "xray_5_icd", "xray_6_icd", "xray_7_icd", "xray_8_icd", "xray_9_icd", "xray_10_icd", "xray_11_icd", "fast_1_icd", "fast_2_icd", "fast_3_icd", "fast_4_icd", "fast_5_icd", "fast_6_icd", "fast_7_icd", "fast_8_icd", "fast_9_icd", "fast_10_icd", "fast_11_icd", "ct_1_icd", "ct_2_icd", "ct_3_icd", "ct_4_icd", "ct_5_icd", "ct_6_icd", "ct_7_icd", "ct_8_icd", "ct_9_icd", "ct_10_icd", "ct_11_icd", "ct_12_icd", "ct_13_icd", "op_1_icd", "op_2_icd", "op_3_icd", "op_4_icd", "op_5_icd", "op_6_icd", "op_7_icd", "op_8_icd", "op_9_icd", "op_10_icd", "op_11_icd").
levels	Character vector of length 2. The levels to use to encode the resulting injury variable. The first item in the vector should be the level to be used to represent having the injury. Defaults to c("Yes", "No").
add.as.factor	Logical vector of length 1. If TRUE the variable is added to the study sample as a factor. If FALSE it is added as character. Defaults to TRUE.
drop.used.variables	Logical vector of length 1. If TRUE the injury variables used to calculate the injury variable are dropped from the sample. Defaults to FALSE.
