you can create your own function:
> fact <- function(n) prod(1:n)
> fact(3)
[1] 6
> fact(10)
[1] 3628800
> fact(c(3,4))
[1] 6
Warning message:
Numerical expression has 2 elements: only the first used in: 1:n
fact() will work for scalars but doesn't do well with vectors.

Many thanks to all who helped with my question last week about how to
take the output of lm() and turn it into code that can be run on systems
without R (using SQL, C, etc). This is a summary of the answers, caveats,
and a solution including a little Perl script I wrote to do this.

You can use gamma(x + 1) for x! or you can use the factorial() function
in the gregmisc package on CRAN.
See ?gamma for the former option.

A consistent Rgui crash (1062 on XP) I was experiencing
seemed initially to be solved by following R Win FAQ 2.12:
placing a generic microsoft msvcrt.exe in rw1062\bin.

Exiting Macro Magic, a keyboard macro utility,

Dear All:
what R function should be used for logit regression? glm()? And, more
importantly, is there a function that would calculate the *probability of
Y given X in the logit framework* (say for propensity score calculation)?

You do need Windows Perl, but I have only tested ActiveState perl.
Cygwin Perl wil not work: it does not understand the Windows paths.
We've never seen a problem with ActiveState perl on XP.

This was discussed here in October. For the multivariate T you can use
rmvt <- function(corr,df)
rmvnor
For multivariate normal and t distribution, install and try package "mvtnorm".
Then look for ?rmvnorm and ?rmvt.

Is there a recommended binary version of perl to use under Windows XP
for `Rcmd build'? The R FAQ for Windows just mentions "perl". I
think that Kevin Wang's document on R for Windows suggests ActiveState
perl but I have not been able to install it.

I can guess you meant `sphericity', but you didn't tell us of what. Note
that the `analysis of variance' is an algorithm to partition sums of
squares, and that makes no such assumption.
I suspect that you could do what you want in lme (package nlme), if you
were able to specify it unambiguously.
Thank you - it works great now.

dlltool is part of the compiler set, so that's where your troubles begin.
However, the instructions are not those for the binary install. All you
need to do is to get RMySQL.zip from CRAN and put RMySQL/libs/libmysql.dll
somewhere in your path.

Hiroyuki -
Function write() with "" as its second argument might do
what you want. This function does not check the "dims"
attribute of its first argument, so you have to set that
explicitly. See help(write), help(format), help(cat).
Seems unfortunate that help(print) does not point backw
