Dear Helmut!

A better way would be to return the vector of ntot (your suggestion in our correspondence) instead of some histogram-data with standard settings.
That would give you all freedom to design the histogram to your needs.

Example: 100 bins in the histogram
code snippet


  hist(res$ntot, freq=F, breaks=100, main=des[j],

       cex.main=0.95, cex.axis=0.9,

       xlim=c(12, 120), ylim=c(0, 0.5), 

       xlab=expression(N[total]),

       col=col, las=1)

  abline(v=c(res$nmean, res$nperc[["50%"]]), lty=c(1, 3))

  legend("topright", box.lty=0, legend=c("mean", "median"), lty=c(1, 3),

         cex=0.9)

Note the pronounced and outstanding role of N=24, the sample size for stage 1. Not so clear seen in your pictures above for OBF or Zheng. Partly now also seen for HP.

❝ I luf open source!

@All: Be warned! You need an understanding of all the code in Power2stage to get this up and running.
