Perhaps like this :
temp =density(b[20:50])
truehist(b, ymax=max(temp$y))
lines(temp)

carol white a écrit :
Consider a vector of 100 elements (attached files). then,
truehist(b)
lines(density(b[20:50]))
How is it possible to have density plots of all subsets like b[20:50] within
histogram (without exceeding the max of historgram on y axis)?
Is it more clear?
Best,

Hi,
I wanted to plot the histogram of a vector and then, plot the density
function of subsets of the vector on the histogram. So I use truehist in MASS
package and lines(density) as follows:
length(b) = 1000
truehist(b)
lines(density(b[1:100]))
I do not undertsand what you mean. Can you please provide a *reproducible*
example?
Uwe Ligges
however the density plot of the first 100 points exceeds the max of y axis
(see attached). how is it possible to make a graphics so that the density plot
of the subsets doesn't go beyond the maximum of all points in the complete
set?
Cheers,
Carol
