Automatic scale scoring from a dic file

This function is deprecated. Please score scales directly from within R. Use the get_scales() and score_scale() functions. This function takes a data frame and a dic file with scale definitions and applies the specified scoring functions to create new variables for each scale. The scoring functions can be specified in the dic file, and if not provided, it defaults to using the mean of the items in the scale. The new variables will be named according to the 'item_name' column in the dic file. The function first checks for the presence of dic information either in the data frame's attributes or as a separate argument. It then iterates through each scale defined in the dic file, applies the specified scoring function to the relevant items, and creates new variables for each scale. Finally, it returns a data frame with the new scale scores.

Usage

score_from_dic(data, dic = NULL)

Arguments

data

A data frame with dic information. The dic information can be provided as an attribute of the data frame or as a separate argument.

dic

A dic file with scoring information. If NULL, the function will attempt to retrieve dic information from the data frame's attributes.

Value

A data frame with added scale scores. The new variables will be named according to the 'item_name' column in the dic file.
