Draw an Ecdf plot showing the distribution of scores in each demographic subgroup

Description

Draws a plot using Hmisc::Ecdf(), overlaying cumulative distribution functions, one for each subgroup specified, and one for overall population. Useful to compare subgroups based on the distribution of scores among people in that subgroup using data from small places like census block groups, based on having for each place the pop total and % of pop that is in each group.

Usage

pop.ecdf.dd(
  e,
  elab,
  mydf,
  dlabs = colnames(mydf),
  mywt = rep(1, NROW(mydf)),
  main,
  mycolors,
  refcolor = "black",
  sorted = TRUE,
  log = "",
  ...
)

Arguments

e	Required numeric vector of scores (e.g., environmental indicator values) for places like block groups, one place per row
elab	Required character single element vector with text label for environmental score, used in xlab of plot
mydf	Required data.frame where each row is a place and each column is the percent of place population that is in given demographic subgroup, one subgroup per column
dlabs	Optional, charater vector that specifies text for legend, same length as number of columns in mydf
mywt	Optional, default is unweighted, but normally would specify as the population counts for places analyzed
main	Optional character specifying plot title at top of plot. Default title notes names of subgroups
mycolors	Optional vector of colors as long as number of columns in mydf, specifies colors of lines
refcolor	Optional color, default is 'black'
sorted	Optional logical, default is TRUE. Should the legend be sorted in order of population weighted mean values of e?
log	Default is ”. Passed to pop.ecdf()
...	Other optional parameters to pass to Ecdf
