[R] Looking for a better way to document my packages

Hi all, Trying to do what my subject says. As I'm trying to be better about making packages out of my code, I'd like the packages themselves to be better, which means *.Rd- documenting my code. The thing is, from years of programming other languages prior to landing in the R pond, I've

I write about R every weekday at the Revolutions blog: http://blog.revolution-computing.com . In case you missed them, here are some articles from last month of particular interest to R users. http://bit.ly/WYAnM shows how to create a URL for a Google Spreadsheet so you can read the data

Hi, I know of three options that resemble your query, - the roxygen package - a ruby script called weeder by Hadley Wikham - the inlinedocs package on r-forge I only ever used roxygen though, so i can't speak for the relative merits of the others. HTH, baptiste 2009/10/1 Steve Lianoglou

Re: [R] Unable to install lme4

This is the first time I've encountered R having difficulty with package and R version compatibility. I cant believe no one has fixed generally so that your version of R can get the latest package appropriate to that version. How nice would that be? :) Anyway, I figured it out for my version

Hi, I think you can also use a qq-plot to do the same, no? You won't get a statistic score + p.value, but perhaps you're more of a visual person? :-) -steve On Thu, Oct 1, 2009 at 12:56 PM, Richardson, Patrick patrick.richard...@vai.org wrote: ?shapiro.test -Original Message- From:

Re: [R] Normal distribution

I don't disagree. And to that end one could probably look at the skewness and kurtosis values as well. A combination of several techniques would probably be a good idea. Best regards, Patrick -Original Message- From: Steve Lianoglou [mailto:mailinglist.honey...@gmail.com] Sent:

Re: [R] Normal distribution

Noela, Package nortest has 5 tests of normality. A word of caution: the wording of your question suggests that you believe that, if the test you use does not reject the normality hypothesis, you then have proof that your data come from a Normal distribution. That's *NOT* true. Normality will

Another interesting visual technique is given by the qreference() function in pkg:DAAG. I've used this type of display effectively with non-stats people as well as in teaching intro courses in stats. (I would randomize the location of the actual-data panel and not use a different colour. The
