Functions within functions in R and S-Plus
...ve tried to "translate" some code from R to S-Plus (I have colleague
that insists on using S-Plus. And yes, I have tried to make him change
to R...)
The following code works out fine in R, but in S-Plus (S-PLUS 6.2 for
Windows Professional Ed.) I get the error message "Problem in
est.theta(x): Object "func" not found ".
I have tried to keep most of the structure in my original problem (but
simplified it!), so the code could seem a bit strange.
I suspect that this has something to do with different scoping rules in
R and S-Plus, but still I have not found a work...

R doesn't understand dates prior to 1 Jan 1970
I'm installing R on an Irix 6.5 machine and R fails to understand dates
prior to 1 Jan 1970. This first cropped up early in the test scripts

problems with garchFit
...t know where is most
appropriate for this topic. Sorry if it bothers you.
I did garch fitting on S&P500 monthly returns with garchFit from fSeries. I
got same coefficients from all cond.dist except normal. I thought that is
probabaly usual for the data. But when I play with it, I got another
question.
I plot skew normal with skew = 1 and a standard normal, they overlap
eachother, so I think they are the same. Skew = 1 means no skewness (I can
not find the paper defining the distribution).
library(fSeries)
curve(dsnorm(x, 0, 1, 1), -2, 2, add = F, col = 'red') #skew normal with

problem with a function
Hi all,
I have a function rho.f which gives a list of estimators. I have the
following problems.
rho.f(0.3) gives me the right answer. However, if I use rho.f(corr[4]) give
me a different
answer, even though corr[4]==0.3.
This prevents me from using a for loop. Can someone give me some help?
Thank you very much in advance....

Method of L-BFGS-B of optim evaluate function outside of box constraints
...ys:
I'm using L-BFGS-B method of optim for minimization problem. My function
called besselI function which need non-negative parameter and the besselI
will overflow if the parameter is too large. So I set the constraint box
which is reasonable for my problem. But the point outside the box was
test, and I got error. My program and the error follows. This program
depends on CircStats package.
Anyone has any idea about this?
Thanks in advance.

as.POSIXct before and after 1970
Can someone, please, explain the difference in as.POSIXct results
before 1970 and on and after 1970 as illustrated below.
After 1970, the use of 'EST' or "EST+5EDT' as the timezone does not
affect the result of asPOSIXct, but before 1970 on 10/28 the results
are different.

as.Date function yields inconsistent results (PR#14166)

Submission from: (NULL) (217.194.59.134)
This piece of code:

zzz2 <- as.POSIXlt("1999-03-18", tz="CET")
zzz1 == zzz2
as.Date(zzz1)
as.Date(zzz2)
yields TRUE for "zzz1==zzz2", but the two dates returned by as.Date are
different:
