Starting to write a blog I need a way how to publish my R codes. One possibility would be to just add some formatting with Pretty R. Nice, but I miss a repository with all codes ever submitted and possibility to make corrections.The final solution was ...
In the past two years, a growing community of R users (and statisticians in general) have been participating in two major Question-and-Answer websites: The R tag page on Stackoverflow, and Stat over flow (which will soon move to a new domain, no worries, I’ll write about it once it happens) In that time, several long (and...
Patrick Burns just posted to the mailing list the following massage: There is now a document called “Some hints for the R beginner” whose purpose is to get people up and running with R as quickly as possible. Direct access to it is: http://www.burns-stat.com/pages/Tutor/hints_R_begin.html JRR Tolkien wrote a story (sans hobbits) called ‘Leaf by Niggle’ that has always...
I thought this up the other night but I'm not sure where I'm going to use it. But I thought that I would through it out there anyway, maybe it will solve all of someone else's problems. I was thinking about classes in R and R is SO NOT object oriented...
No that is not a typo in the title. In my programming a came across a solution that I thought was pretty cool. I have a function that basically takes two objects and passes the elements of the objects to another function as arguments. This is a pret...
OK in the last two tips I explained how functions can return functions and how to leverage expressions. Now lets get complicated. This is really how my testing code works; expressions embeded in expressions that are passed to functions that return fu...
I never really saw a use for these until I started testing code en mass. I found myself doing lots and lots of copy and paste. I heard it from Steve McConnell in his Code Complete book where he said if you are copying and pasting you are programming ...
I've been really busy lately working on my dissertation and applying for jobs. But I've found a few really cool things that I'd like to share. These are pretty complex things so lets break it up into a few tips. First Tip: did you know that you can re...
I found another gem in R today. Earlier I commented about how R could do recursion, something that I love. I write some pretty complicated recursion functions in my research, but I also have a bad habit of compulsively reorganizing things. Now I've c...
I got asked the question the other day about how to get to the internals of a function. I realized that this was not something that I had covered yet on my tips blog. read more
