[R] density plot with frequency units

I would like to create a kernal density plot, but rather than show density units on the vertical axis I would like frequencies. I know histograms do this but I don't want the bars, just the density curve. Thanks! __ R-help@r-project.org mailing list h

[R] density plot for weighted data

I'm trying to create a density plot using census data, where the weights don't sum to 1. >plot(density(oh$FINCP,weights=oh$PWGTP)) Warning message: In density.default(oh$FINCP, weights = oh$PWGTP) : sum(weights) != 1 -- will not get true density How would I go about doing this? Thanks!

Re: [R] help with algorithm

Thanks for everyone's suggestions. I think looping is the way to go. I have 50 files on which I need to apply the same procedures, so I'll try and wrap my final code in some sort of loop. > > highest and lowest groups)? (I can do this in multiple steps* but wonder > > what the best, "R way" is

[R] help with algorithm

I'm wondering if anyone can give some basic advice about how to approach a specific task in R. I'm new to R but have used SAS for many years, and while I can muscle through a lot of the code details, I'm unsure of a few things. Specific questions: If I have to perform a set of actions on a grou
