What is the best way to lag a time series?
Dear R-users,
I've been using R for a while and I am very satisfied! Unfortunately, I
still have not figured out an efficient and general way to construct and
use lags of time series, especially when I need to work with different
packages.
Let me give an example. I have two time series x and y and I want to
estimate a variaty of distributed lags models and run different tests

Fortune?
I think the rule is that you can do anything as long as you don't
complain. If you want to complain, you must follow the instructions.

Data Frame as Hash Table
I'm interested in using a data frame as if it were a hash table. For
instance if I had the following,
> (d <- data.frame(key=seq(0.5, 3, 0.5), value=rnorm(6)))
key value
1 0.5 -1.118665122
2 1.0 0.465122921
3 1.5 -0.529239211
4 2.0 -0.147324638
5 2.5 -1.531503795
6 3.0 -0.002720434
Then I'd like to be able to quickly retrieve the "value" of "key" 1.5

My first package
Hi All,
I'm planning to submit my first package to R, and although I read all the
documentation, I'm not very clear on the following 2 items, from which I'd
appreciate your guidance:
1)I understand it is suggested to use the R dev version to build the
package. Which one specifically should I use to build a package on a Mac
OS? How about package dependencies, which version should I

arr.ind argument to which.min and which.max
Is there a reason that 'which.min' and
'which.max' don't have an 'arr.ind'
argument?
The context in which I wanted that was
a grid search optimization, which seems
like it would be reasonably common to me.

wishlist: decreasing argument to is.unsorted
I've just realized that it could be handy
to have a 'decreasing' argument in 'is.unsorted'.
And I'm cheekily hoping someone else will
implement it.
It is easy enough to work around (with 'rev'),
but would be less hassle with an argument.
The case I have in mind uses 'is.unsorted' in
'stopifnot'.

TensorFlow in R
Hi All,
I didn't have much success through my Google search in finding any active
R-related projects to create a wrapper around TensorFlow in R. Anyone know
if this is on the go?
Thanks,
Axel.

Reproducibility issue in gbm (32 vs 64 bit)
Dear List,
The gbm package on Win 7 produces different results for the
relative importance of input variables in R 32-bit relative to R 64-bit. Any
idea why? Any idea which one is correct?
Based on this example, it looks like the relative importance of 2 perfectly
correlated predictors is "diluted" by half in 32-bit, whereas in 64-bit, one
of these predictors gets all the importance

two questions for R beginners
* What were your biggest misconceptions or
stumbling blocks to getting up and running
with R?
* What documents helped you the most in this
initial phase?
I especially want to hear from people who are
lazy and impatient.
Feel free to write to me off-list. Definitely
write off-list if you are just confirming what
has been said on-list.

Constrained Optimization in R (alabama)
Dear List,
I'm trying to solve this simple optimization problem in R. The parameters
are the exponents to the matrix mm. The constraints specify that each row
of the parameter matrix should sum to 1 and their product to 0. I don't
understand why the constraints are not satisfied at the solution. I must be
misinterpreting how to specify the constrains somehow.

R on 64-Bit…
Dear R users,
I know this issue came up in the list several times. I’m currently running
R on 32-bit on Windows and due to memory limitation problems would like to
move to a 64-bit environment. I’m exploring my options and would appreciate
your expertise:
1) Windows 64-bit: Prof. Brian Ripley recently posted the experimental
built of R for win 64-bit. I’ll appreciate any feedback on

breaking ties in order() based on many vectors
The order() function allows you to specify multiple vectors, which are used
successively to break ties. If I want to use many vectors to break ties
(say, 25 or more), that are columns of a matrix or elements of a list, does
anyone know a shortcut to do this without passing 25 arguments to order()?

Add wrapper to Shiny in R package
Dear List,
I'm trying to add a function that calls a Shiny App in my R package. The
issue is that within my function, I'm creating objects that I'd like to
pass to the app. For instance, from the example below, I'm getting
"Error: object
'xs' not found". How can I pass "xs" explicitly to shinyApp()?
*Under R directory:*

Repetitive correlation test
Dear all,
Through the following code, I wanted to perform correlation test repetedly (through loop) on different combinations of variables of a data set.
Code:

nm = names(x)

Popularity of R, SAS, SPSS, Stata...
Hi All,
I've been fiddling around with various ways to estimate the popularity
of R, SAS, SPSS, Stata, JMP, Minitab, Statistica, Systat, BMDP, S-PLUS,
R-PLUS and Revolution R. It's not an easy task. You can see what I've
come up with so far at http://r4stats.com/popularity . I'm sure people
will have plenty of ideas on how to improve this, so please let me know
what you think.
