[R] Overlapping subject-specific histograms

[PIKAL Petr]

Hi

change

points( factor(names(tab)) + dist.overlap, data$sim[kat == i] ,
> type="h", col=2, lw =4)

to

points( 1:length(data$count[kat == i]) + dist.overlap, data$sims[kat == i] , type="h", col=2, lw =4)

And do not use html post, your code could be scrammbled.

Cheers
Petr
