calc_vs: Calculate vector score

In iholzleitner/facefuns: Convenience Functions Around 2D and 3D Face Shape Analysis

Description

Function projects data onto vector from anchor one (score of 0) to anchor two (score of 1). For all three arguments, input must be two-dimensional data frame or matrix with rows = specimens, and columns = PC scores.

Usage

calc_vs(data, anchor1, anchor2)

Arguments

data	PC scores of face(s) for which vector scores are to be calculated
anchor1	PC scores of face(s) which will constitute lower anchor point
anchor2	PC scores of face(s) which will constitute upper anchor point

Value

Returns tibble with columns "id" and "VS". If data contained rownames, these will be saved as ids.

Examples

# CALCULATE FEMALE-MALE VECTOR SCORES
data("LondonSet_scores")
data("LondonSet_info")

fem <- LondonSet_scores %>%
  dplyr::filter(row.names(LondonSet_scores) %in%
  LondonSet_info$face_id[which(LondonSet_info$face_sex == "female")])

mal <- LondonSet_scores %>%
  dplyr::filter(row.names(LondonSet_scores) %in%
  LondonSet_info$face_id[which(LondonSet_info$face_sex == "male")])

calc_vs(LondonSet_scores, fem, mal)
