#' @title Make text to be shown in popups on Envt data map
#'
#' @description
#'   Takes raw values and what percentiles they are at,
#'   and presents those as a text field to be used as the text in a popup window on a map
#' @details
#'   Could edit code to NOT put in the units when value is NA?\cr
#'   Could edit code to handle cases like only one row, matrix not df?\cr
#'   Could fix to use only one space when no units\cr
#'   \cr
#'   EJSCREEN as of 2015 used 85 pctile.text. fields, for popup text, like "pctile.text.EJ.DISPARITY.pm.eo"\cr
#'   \code{
#'    names(bg2)[grepl('pctile.text', names(bg2) )] \cr
#'    length( bg2[1, grepl('pctile.text', names(bg2) )] ) \cr
#'    # [1] 85 \cr\cr
#'   }
#'
#'   In EJSCREEN, there are three types of pctile.text fields: E (text varies), D, EJ:\cr
#'   \code{
#'     'pctile.text.cancer'                            "55 lifetime risk per million (91%ile)"     \cr
#'     'pctile.text.pctmin'                            "13% (30%ile)" \cr
#'     'pctile.text.EJ.DISPARITY.cancer.eo'            "36%ile"    \cr\cr
#'     }
#'   For E popups, text includes units:\cr
#'   (neuro was only in 2015 version, not later versions of EJSCREEN)\cr\cr
#'  \code{
#' names.e.pctile[names.e.pctile != 'pctile.neuro']\cr

#' @param e raw environmental indicator values for various locations
#' @param pctile required integers 0 to 100, representing the percentile(s) at which the raw value(s) fall(s).
#' @param prefix optional, default is 'pctile.text.'  This is a text string specifying the first part of the desired resulting fieldname in outputs.
#' @param basenames optional, default is colnames(e). Defines colname(s) of outputs, which are the prefix plus this.
#' @param units optional character vector with one per column of e, default is the units used for the latest (2016) version of EJSCREEN environmental indicators,
#' such as 'ppb' and 'ug/m3' -- function will try to use units appropriate to basenames, looking in data(popupunits), and use '' (blank) if no match is found.
#' @param sigfigs optional, numeric vector with one per col of e,
#'   defining number of significant digits to show in popup,
#'   defaulting to rules in EJSCREEN latest (2016) version,
#'   or just 2 for basenames not found in data(esigfigs).
