In fdadensity: Functional Data Analysis for Density Functions by Transformation to a Hilbert Space

#' Baby name popularity densities for 50 male and 50 female names in the USA
#' 
#' Baby name popularity densities, obtained by smoothing year-to-year popularity indices from 1950 to 2016, after normalization to have integral equal to 1.  
#' The top 50 names, in absolute popularity, are included for each gender.
