Thank you for your advices.
I will try even increased "gamma" values, and all-out cross-validations.

Hello Randy
I get emails like this quite a lot.
The most likely problem is in the installation of
the gsl library. To verify that it is in fact installed,
try to compile and run the little Bessel function
example given in gsl-ref, section 2.1.
Get this working first. If it works, this means

Dae-Jin,
Thanks for your (offline) persistance: you are right the problem is with
`gamm'. There was a dimension dropping error in `formXtViX' (called by
`gamm') for group sizes of 1 (as occurs when you have a random effect per
observation). This will be fixed in mgcv_1.3-28.
best,
Simon

Hello, Thierry
Thank you for the fast reply
actually my php script is not correct, the correct logic is R script, by
writing this peace of code in php I tried to do the same logic that R script
does. But this php programm algorirm probably is not correct so results are
incorrect also.
I am tryi
I have generally found that both RDCOMClient and rcom do work although
around the time of new R versions one might be ready for it before the other
so try both.

Thank you for valuable advices.
I'm sorry Dr. N. Wood that by mistake I sent this reply firstly to
your personal e-mail address.
I will use the "min.sp" argument when the data size is very small. I'd
like to know if there is any criteria for selecting "min.sp."
I compared gamma=1.0 and 1.4, and I
hi,
i was trying to perform a function from the RDCOMClient package. to make
it short: i tried to run the example in ?.COM, namely
e <- COMCreate("Excel.Application")
books <- e[["Workbooks"]]
as soon as e[["Workbooks"]] is called, the RGUI crashes. debugging the
function .COM reveals that some
I am using R.2.4.1 on Windows XP 5.1 (SP 2).
I have the following line in my R code.
Analysis=anova(lm(PM ~ x))
It works the first 60 or so times it is called but
then I get the following error message.
Error in lm.fit(x, y, offset = offset, singular.ok =
singular.ok, ...) : 0 (non-NA) cases

1. you could place the commands in a file and source the file each
time you want to run it or it might be good enough to place it on the
clipboard and then just do source("clipboard")
2. Thomas Lumley's defmacro in R News 1/3 could be used
Neither of these two require that you do anything specia
