Arguments

X

input data matrix or data frame with items of the EORTC QLQ-OG25 in columns. Missing values are inserted as NA.

id

name of the variable in the dataframe X corresponding to the patient identification number

time

name of the variable in the dataframe X corresponding to the time identification number

Value

Y

a data frame with the id and time variables of dataframe X and the score obtained for each dimension. Each score is represented by one column of Y. The names of the scores are those proposed in the scoring manual. If id and time parameters are not specified, then Y only contains the scores

Details
