I would like to calculate the percentage frequency distribution of h1 and h2. How can I combine h1 and h2 on the same plot? The length of the vectors are different in h1 and h2. I tried the following code. it gives the plot for h1 only. your suggestions would be appreciated!!

h = hist(h1)
h$percentage = h$counts/sum(h$counts)*100
plot(h, freq=F, xlab=
'Proteins', ylab='Percentage')

@ayyappadas342 between the plots , it says hold on so that you can plot another plot on an existed one! for example plot(x,y); par(new=TRUE); plot(x,y)  

in case you are calling someone , it is better you call it with a correct name so that s/he will see your comment . You should have written @Mo and not @mo . that is why I did not see your comment
