Dear list users,

This follows up on Duncan Murdock's reply to Boris Steipe's question
about possible advantages to using RStudio.
I agree with Mr. Murdock's list of advantages of RStudio, but disagree
mildly with his comment about feeling that the tiled display provides
too little space. When I use RStudio, I

Hi all,
This question is sort of related to R (I'm not sure if I used an R function
correctly), but also related to stats in general. I'm sorry if this is
considered as off-topic.
I'm currently working on a data set with two sets of samples. The csv file
of the data could be found here: http://pa
The RStudio editor itself is pretty mediocre. It is the context sensitive
tab-completion with as-you type help that sells it to me anyway. That, with
debugging and roxygen and knitr support really make it worth looking at.

If you're going to use splines, another possibility is mgcv::gam (also
part of standard R installation)
require(mgcv)
gam(DV ~ s(IV), data= YourDataFrame, family=binomial)
this has the advantage that the complexity of the spline is
automatically adjusted/selected by the fitting algorithm (alt

Here is a question that I might ask. What are the alternatives to R and
how does R compare? That is, for what class of problems is R the best
tool around?

Change that column to be a factor with the levels in the order that you
wish.
dataFrame$column <- factor(dataFrame$column, levels=c(1:150, "S", "Z"))
Then it will sort in that order. E.g.,

> d[order(d$One),]

Ask if they have a favourite R programmer. This will tell you how much into
the R culture they are, and perhaps also tell you if their opinions of a
good programmer concur with yours...

1. What have they done in the way of R package development? If they've done
that, then you can review packages they've worked on and ask questions about
that (the package development process as well as the documentation they wrote)
to see if that's of sufficient quality.

Hi,
I would like to sort a data frame by a column, the column to sort by has a
list of numbers 1:150 (a few numbers are missing so the total is 137) and
two letters "S" , "Z". How can I sort it so that first I have the numbers
in running order (1,2,3,...150) and then the letters S and Z?
