Grapevine pips outlines (two views) with elliptic Fourier transform coefficients

Source: R/data.R
vitis.Rd

A dataset containing 410 pip outlines (dorsal and lateral view) that have been preprocessed and transformed using elliptic Fourier analysis (5 harmonics). This dataset is used for demonstrating statistical methods in Momstats.

Usage

vitis

Format

A tibble with 410 rows and 5 variables:

  • id: for the accession

  • pip: Numeric identifying pip number

  • accession: Character 14 names

  • status: Factor with 2 levels (domesticated/wild)

  • length : pip length measured before outline normalization

  • VD: 5 eft harmonics for dorsal view

  • VL: 5 eft harmonics for lateral view
