Description Usage Format Source References Examples

Raw data from the Baranzelli et al. (2014) study on morphological selection in the flowers of Morrenia brachtephana. These data were downloaded from Dryad and then formatted for use in this R package. Flowers consists of the following variables:

wm: relative male fitness, based on the average number of pollinaria exported per flower from all the flowers sampled for each individual (Pollinarium.export).
wf: relative female fitness, based on the average number of pollinia received per flower from the total number collected per individual (pollinia.import).
Wm: absolute male fitness, based on the average number of pollinaria exported per flower from all the flowers sampled for each individual (Pollinarium.export).
Wf: absolute female fitness, based on the average number of pollinia received per flower from the total number collected per individual (pollinia.import).
At3: width of the corona, a trait related to the visual attraction of the flower.
Gy2: width of the inner guide rail, a trait related to pollinaria transfer.
Gy3: width of the inner guide rail at the level of the upper edges, a trait related to pollinaria transfer.
Gy4: length of the inner guide rail, a trait related to pollinaria transfer.
Gy5: length of the outer guide rail, a trait related to pollinaria transfer.
Co3: length of the corpusculum, a measure of the pollinarium.
Ca3: length of the caudicles, a measure of the pollinarium.
individual: individual identification number.
