Hello world!


I suppose that “Hello World” is the first thing that any blogger should do when starts a blog. So here I go “HELLO WORLD!!!” The aim of this blog is to gather my thoughts and experience around learning R and hopefully to get a lot of insights from my readers.

Officially this is my third attempt to learn R and I must say things are looking up this time. I think in the first 2 occasions the problem I had was related to trying to learn R in the same way I learnt SAS and SPSS. R is a different piece of software and therefore needs to be learnt in a different way.

This time I am using the R for SAS and SPSS users  book as my bible and now  I am able read the R short reference card without thinking “how can I translate this chinese to english?”. I’d recommend this book to anybody wanting to learn R, even for those of you who don’t know SAS or SPSS as the explanations are very clear and is just at the end of every chapter where you can see a comparison between R and SAS & SPSS.

Anyway, I hope you enjoy my journey and definitely I hope you can get some valuable ideas from my posts.

    Have you seen the R for SAS and SPSS users? It really helped me. Should be available free online as a PDF.

    Hi Alberto,

    I’m glad you’re finding my book helpful. R drove me a bit nuts at first, mostly because it was so very different from SAS & SPSS. Much of the documentation assumed you already knew a fair amount about it.

    For folks who haven’t seen it, you can still download an early version for free at http://www.r4stats.com.

    Cheers,
    Bob

      Bob,

      Your book is fantastic! Chapter 9,10 and 11 are my bible so far! Believe it or not the tip about the function fix() paid for the entire book! ;-)

      Cheers,

    Alberto,

    That’s funny, an anonymous reviewer wrote that chapter 11 (selecting observations) was totally redundant once you understood chapter 10 (selecting variables). To an R expert, that’s probably true. But I still find it much easier to look at the example that is specific to one or the other, even though they’re so similar.

    Have fun!

    Bob
