[R] Histogram

[Anupam]

Thanks. That is the type of graph I want, except with more options and
combinations. Here is an example with percent on Y-axis:
http://i.imgur.com/pr8M3.jpg This combines both 'histogram' and 'cumulative
histogram' type of data. In place of straight lines connecting the points I
want step-functions. I already have heights (y) and end points of x
intervals in a file (except for the last, x1-x2, where I only have x1). The
points are heights, left-continuous (they are at the end of the x1-x2
interval, and do not include x2).

It's difficult to understand what exactly you're looking for without seeing
an example, could you post a simple version?  imgur.com is a website that
lets you quickly upload pictures to share with others.

I think your problem can be solved with the type='s' option to the general
plot routine.  Consider the following three plots, I think the third is the
one you're looking for.

x = runif(10,0,1)
x2 = cumsum(x)

plot(x2)
plot(x2,type='l')
plot(x2,type='s')

Hope that helps,
Sam Stewart
