R: using Matplot to plot multiple curves same graph and scale

R: using Matplot to plot multiple curves same graph and scale

I have a table: y
1 2 3 4 5 6
0.2414412019 0.5032905670 0.1956391677 0.0422788008 0.0081100844 0.0015289503

0.0001994283 0.0005318088 0.0003323805 0.0000664761
is.table(y)
[1] TRUE
Originally, if I want to create a plot, I could simply do plot(y), which
look likes this
However, now I would like to add another curve to this plot, i.e.
dpois(1:42, lambda = 10). And I would like to preserve the scale by using
matplot. But since y is a table not a vector, I have no idea how to use
matplot to solve the problem. I do not want to use par(new = T) blablabla,
since it doesnt always preserve the scale and I am working with many
tables with different length
Note: my goal is to reproduce the plot above (the vertical lines must be
preserved, I do not want histogram or bars. In other words, I wish the
table structure of y can be preserved) with an additional curve on the
same graph. Can I use matplot or other function to achieve this in R?
