Add a rowwise mean or sum index of specific variables to the dataset.
add_index(data, name, ..., type = "mean", na.rm = TRUE, cast.numeric = FALSE)
| data | a tibble |
|---|---|
| name | Name of the index column to compute. |
| ... | Variables used for the index. |
| type | Type of index to compute. Either "mean" (default) or "sum". |
| na.rm | a logical value indicating whether |
| cast.numeric | a logical value indicating whether all variables selected
for index computation should be converted to numeric. Useful if computing
indices from factor variables. Defaults to |
a tibble
get_reliability() to compute reliability estimates of added index
variables.
