Dear R community,
Please let me know if there is an R data set with time to multiple outcomes
(unordered failure events of different types).
I am specifically looking for non-competing risks so that I can have observed
times for both outcomes. Twin data or recurrent data will not work for me

Hi Mike,
As long as you have access to some user folder, you can download a
non-install version of RStudio.
Go to the page http://www.rstudio.com/ide/download/desktop and select "Show
zip/tarball downloads", download, extract, and run.
Do believe Yihui that running an example using RStudio saves yo
Hi,
@Yihui
When I am using a public computer, say university computer lab or
financial company. I do not have control what to install.
I'm also very happy with R editor on OS X, it integrates with Mac
well. As for my Mac Air, I am keeping installation to the minimal.
There are a lot links on yo
Hi Mike,
if you browse the folders, you find always the Rscript binary (the executable)
under /Library/Frameworks/R.framework/Versions/.../Resources/Rscript.
Do not forget to give your tex file the extension .Rnw! Then surround each
Rcode with <>= Here your r code as you do it in the R shell .
I recommend RStudio not because I want to promote it in any sense, but
because of the fact that it has the best support for Rnw/knitr at the
moment, and it will save you a lot of headache to get started. It
seems you just do not believe me, and insist on going through all the
low-level configuratio

Thanks, Simon. I would never figured it out!
I apologize if I sound frustrated, because I am.
@package author: you have a great package, but I think a lot of the
directions are hand waving. For the newbies, this leads to more
confusion.
@Berend: I am using OS X.

The executable is in case of knitr always Rscript.
On a mac it is simply Rscript on windows it is Rscript.exe. This should be on
your PATH. If you are not sure, open the Mac Terminal and type Rscript
--version. If it does not say "Command not found" all is fine.

In step 3: "add the executable file (step 3)".
What is the executable file? Locate package knitr directory path in R?

Hi Simon,
I am on OS X Lion, I have TeXworks, I don't have knitr as an option.
How do I install that into TeXworks? Seems like I have to something
in terminal?

Hi Mike,
I found my way with this little blog: http://yihui.name/knitr/demo/editors/
The .Rnw files are created very well in a Latex editor. Everything else can be
easily googled. The command via knitr::knit2pdf works very fine if you use the
chunks. If you are trying to compile an Rtex file, t
How do you create a .Rnw file, in R or LaTex? I don't think any
tutorial mentions it.
btw, I am very new to the terms like markdown, so I don't understand

I'm not sure what your question really is. You do not have to use

because it does a lot of automatic conversion behind the scenes (e.g.
tex to PDF, markdown to HTML, ...). If you want a "pure" solution

Hi everyone,
I am using package knitr, FIRST TIME. I don't have access to RStudio.
Read through Yihui's page, didn't find it helpful. Stuck on terms
Rnw, GFM (GitHub Flavored Markdown). Never used Sweave, so the
reference is not helping.
Is there a simple step-by-step example WITHOUT RStudio?
Try
subset(Dat, AA == "A" | (AA == "B" & BB == "b"))

Hello,
You can easily make of the following a one-liner. Note that the order of
rows is not the same as in your code, so identical() will return FALSE.
idx <- Dat[, 'AA'] == "A" | (Dat[, 'AA'] == "B" & Dat[, 'BB'] == "b")
res2 <- Dat[idx, ]
Hope this helps,
