Collect mean shapes and add to original data

Add mean shapes back to the original data, matched by group.

Usage

# S3 method for class 'stat_meanshape'
collect(x, data = NULL, prefix = "mean_", ...)

Arguments

x

A stat_meanshape object

data

A tibble. If NULL, uses the original data from the analysis.

prefix

Character. Prefix for mean shape columns. Default "mean_".

...

Additional arguments (reserved)

Value

A tibble with mean shape columns added (and their _i inverses)

Details

For grouped mean shapes, mean shapes are matched back to original rows by group membership. For global mean shapes, the same mean is added to all rows.

New columns added:

• {prefix}{coe_col}: Mean coefficient column (e.g., mean_VD)

• {prefix}{coe_col}_i: Mean shape (e.g., mean_VD_i)

Examples

if (FALSE) { # \dontrun{
ms <- vitis %>% stat_meanshape(status)

# Add mean shapes to data
vitis_with_means <- collect(ms)

# Custom prefix
vitis_with_means <- collect(ms, prefix = "grp_mean_")
} # }
