R Overlap plot and histogram -

i need plot histograms , graph in same plot. having problem ggplot2 becouse dataset big.

what can do?

here example

lambda=seq(0,1,length.out=100) b1=lambda^2 b2=lambda^2+1  b=cbind(b1,b2) perc=rnorm(100) matplot(lambda,b) hist(perc) 

thanks :d

sorry question not clear. need have b , histogram overlapped in same plot. plot in slide.

this time can not use ggplot becouse dataset big , takes times.

you not (yet) using ggplot2, , if need other commands control layout, think want (for base graphics) par command.

lambda=seq(0,1,length.out=100) b1=lambda^2 b2=lambda^2+1  b=cbind(b1,b2) perc=rnorm(100) par(mfrow = c(2,1)) matplot(lambda,b) hist(perc) 

this yields matplot top chart, , hist second chart.

if want side-by-side, use par(mfrow = c(1,2)).

as noted in comments, if want them on top of each other call `par(new = true) in between plot commands follows:

matplot(lambda,b) par(new = true) hist(perc)
