#' Pedro Jordano. 25 Mar 2012.
#'
#' Data from a field project during the Frugivory and Seed dispersal field course, 2012.
#'
#' Visitation data come from 140 h direct watches. A data.frame with 42 obs. of 37 variables.
#'
#' First 6 variables are codes for Class, Order, Family, Genus, Species, and species label.
#'
#' Variables include:
#'
#' totvis- Number of visits recorded, pooled all trees.
#'
#' totbic- Mean number of peckings to Cecropia catkins during a single visit. Birds do several peckings and ingest the seeds from these small pieces of the catkins. This may be used to estimate ingestion rate per visit.
#'
#' sde- Effectiveness estimate for the quantitative component, totvis * totbic.
#'
#' Columns 10-37 are the number of visits recorded to each individual Cecropia tree.
