Response to R across the university
...well!
Statistics doesn't always have a positive image. I can recommend
running an R course as one way of making a good impression.

R outside of universities
...interesting to know just how widely R is used, where it is used most
(and where least or not at all). Does anyone have a good overview?

Using interactive plots to get information about data points
I have been experimenting with interactive packages such iplots and playwith.
Consider the following sample dataset:
A B C D
1 5 5 9
3 2 8 4
1 7 3 0
7 2 2 6
Let's say I make a plot of variable A. I would like to be able to click on
a data point (e.g. 3) and have a pop-up window tell me the corresponding
value for variable D (e.g. 4). I am also trying to produce multiple

pairs plots in R
Hi,
is there a way to take a data frame with 100+ columns and large data set to do efficient exploratory analysis in R with pairs?
I find using pairs on the whole matrix is slow and the resulting matrix is tiny.
Also the variable of interest for me is a binary var Y or N .
Is there an efficient way to graphically view many variable relationships that does not look teeny ?
I could do

Identifying points in a plot that have duplicate values
I have code like this: -
#-----------------------------------------------------------------------
------------------------------------------------------
x=scan()
0 0 0 0 0 1 2 3 4
y=scan()
1 1 1 2 2 1 3 4 5
plot(x,y)
identify(0,1,3) #Allows me to select manually to identify co-ordinate
(0,1) as being duplicated 3 times
identify(0,2,2) #Allows me to select manually to identify co-ordinate

History pruning
Hi,
I find that a typical workflow for me looks something like this:
1) import some data from files
2) mess around with the data for a while
3) mess around with plotting for a while
4) get a plot or analysis that looks good
5) go back through my history to make a list of the shortest command
sequence to recreate the plot or analysis
6) send out that sequence to colleagues, along with the
