In ejanalysis/analyze.stuff: Miscellaneous Tools for Analyzing Data in Rows and Columns

Overlay two simple histograms (pdf=probability density functions, not pdf filetype)

Description

Overlay two simple histograms, for data below vs above a cutoff

Usage

pdf2(x, binx, threshold, n = 100, colors = c("gray", "red"), ...)

Arguments

x	Variable for histogram
binx	Variable that defines subsets
threshold	Variable that defines cutoff, so binx<threshold is plotted first, in one color, then binx>=threshold in other color is drawn over that
n	Default is 100. n is just passed to the hist function.
colors	Character vector length 2, with colors for first and second histogram
...	Other named parameters sent to hist, such as main, xlab, ylab

Value

Just plots using hist.

Examples

  ## Not run: 

 e <- bg$pm[!is.na(bg$pm)]
 dpct <- bg$pctmin
 dcount   <- bg$pop[!is.na(bg$pm)] *      dpct[!is.na(bg$pm)]
 refcount <- bg$pop[!is.na(bg$pm)] * (1 - dpct[!is.na(bg$pm)])
 brks <- 0:17
 etxt <- 'PM2.5'
 dtxt <- 'Minorities'

 pop.cdf(        e, pcts = dpct, pops = bg$pop)
 pop.cdf2(       e, dcount, refcount, etxt, dtxt, brks)
 pop.cdf.density(e, dcount, refcount, etxt, dtxt )

  pdf2(
  log10(bg$proximity.npl),
  bg$bin.EJ.DISPARITY.proximity.npl.eo, 10,
  main ='npl for high top 10 pct vs low EJ', xlab='NPL score log10'
  )
  
## End(Not run)
