map_elongate_df {idmact}

Elongate Data Frame Mapping of Raw Scores to Scale Scores

Description

This function takes a data frame that maps raw scores to scale scores, and elongates it. Each raw score range in the 'map_raw' column is split into individual scores, and each corresponding scale score in the 'map_scale' column is repeated for each individual raw score. The function returns a new data frame with each raw score paired with its corresponding scale score.

Usage

map_elongate_df(df_map, map_raw, map_scale)

Arguments

df_map

A data frame that maps raw scores to their corresponding scale scores. The 'map_raw' column should contain ranges of raw scores as strings (in the form, "1-5"), and the 'map_scale' column should contain the corresponding scale scores.

map_raw

A string representing the column name in 'df_map' that contains the raw score ranges.

map_scale

A string representing the column name in 'df_map' that contains the scale scores.

Value

An elongated data frame where each row represents a raw score and its corresponding scale score.

Examples

# Create a data frame mapping raw score ranges to scale scores
df_map <- data.frame(
 raw = c("1-5", "6-10"),
 scale = c(10, 11)
)
# Elongate the data frame
elongated_df <- map_elongate_df(df_map, "raw", "scale")
print(elongated_df)
