Package naming best practices
R-devel,
I'm in the process of choosing a name for a new package. I've already
decided that the name will have two parts, 'portfolio' and 'sim', but
can't decide between 'portfolioSim' and 'portfolio.sim'. Is there any
good reason to choose one over the other?
Thanks in advance,
Jeff

Portfolio Optimization
Hi,
I'm an R newbie and I've been struggling with a optimization problem for
the past couple of days now.
Here's the problem - I have a matrix of expected payouts from different
stock option strategies. Each column in my matrix represents a different
stock and each row represents the return to the strategy given a certain
market move. So the rows are not a time series of percentage

Daily package check and --install=no
R-devel,
There has been some confusion on the MatchIt package mailing list on
the meaning of [--install=no] in the comment column of CRAN's
automated package check.
It's my understanding that, at the very least, a package marked like
this will not have its test cases run each night. Are there other
checks that are omitted?
How, if at all, are such install flags related to the

NAs in unsplit factor
R-devel,
Below is a simple example calling split and unsplit on a numeric
vector of length 2 where 'f' is c(1,NA).
> unsplit(split(c(1,2), c(1,NA)), c(1,NA))
[1] 1 0
I noticed that the call to vector in unsplit gives us 0 as the 2nd
element of the result.
Is this the intended result, as opposed to NA?
Thanks for your help,
Jeff

Hi,
Complete newbie to R here. Just getting started reading manuals and
playing with data.
I've managed to successfully get my *.csv files into R, however I

Forming Portfolios for Fama / French Regression
Hi mates,
I have a problem. I am new to R and want to conduct the Fama/French asset
pricing test. As I am from Germany, I cannot use the already computed
factors from French's website, but need to compute them myself. So I have to

Hello everybody,
I'm running into an issue with the fPortfolio package.

portfolio.optim and assets with weigth equals to zero...
Hello.
I don't understand a particular output of portfolio.optim (tseries).
I have 4 assets and the portfolio.optim returns an asset with weight equals
to zero.
If I do a portfolio.optim with 3 assets, without the asset with weight
equals to zero,
it returns a completely different result.
That's I would expected the same weights as the run with 4 assets.
Below the code.

CRAN R Help
Dear Katherine,
For your first question:
If you are creating these files in a specific folder, then
list.files()
#[1] "Individual_Present_Value_BONDS.csv"? "Individual_Present_Value_Equity.csv"
#[3] "Individual_Present_Value_FOREX.csv"
gives you which files are present.? But, suppose you have other files too in the folder and you want to check only the above
