In PFLR: Estimating Penalized Functional Linear Regression

#' Truck emissions data 
#'
#' The particulate matter emissions data, taken from the Coordinating Research Councils
#' E55/E59 research project (Clark et al. 2007). In the project,
#' trucks were placed on the chassis dynamometer bed to mimic
#' inertia and particulate matter was measured by an emission analyzer on standard test cycles. The engine acceleration of diesel
#' trucks was also recorded.
