The green book tells:The basic technique is classic :keep it simple .A long

Hi
I have R 2.2.0 and SUSE 10.0 installed. When I try to install the package
RMySQL I get the error that the library libz could not be found. This is
strange because I find the library libz.so.1 in the directory /usr/lib/.
Can anybody help? Thanks a lot in advance, Dominic

I guess this isn't so much of a help request as a show-and-tell from a
non-statistician homebrewer who has been fumbling around with R. If
nothing else it provides yet another data set. I hope it is not out of
line.
Anyway, the plots I have produced are at
Thanks for your speedy reply! Now it worked fine. After installing via Yast
the package mysql-devel there was the library libz.so and afterwards I
could install RMySQL without errors.

Hallo all,
I have a question concerning the weights used in the glm function.
I need to build a linear model (family=gaussian) with only one regressor. Sadly
I have only 6 different sets:
y_i=alpha+beta*x_i , i=1,2,3,4,5.
i=1,2,3,4,5 has been observed 60 times, while i=6 has only been

Hi All,
after searching a while on the R-project help archives, I found that I can
construct factorial design with the conf.design package.
Have a look at CRAN package AlgDesign

But now, how can I construct a design for 2 parameters at 3 levels and 1
thanks all; this makes sense now. For what
it's worth, this came up in the context of

Dear list,
Has there been any success in loading modules written in f90? I tried
% ifort -c myfile.f90
% R CMD SHLIB myfile.o
% R
dyn.load('myfile.so')
.Fortran('myfile')
I used intel (free) fortran compiler under linux. All commands run
successfully except that function myfile is not loaded.

If there are symbols present then unix 'nm' should show them to you.
Interestingly:

dyn.load('myfile.so')
is.loaded('myfile_')

..Fortran('myfile_')
Error in .Fortran('myfile_'):

So, myfile_ is

Make sure you have your environment variable LDFLAGS set to -L/usr/
lib, otherwise I believe the linker doesn't look there.
You can check where R looks in the Makeconf file, under LDFLAGS.
Not too sure though - just slogged through building on a brand new
Solaris box, and that was my problem.

Hi Deepayan,
my error bars are delta; they should be transformed as Di - Disigma,
Di+Disigma, being let's say lower and upper, respectively.
To that both my y (Di) as the error bars should be in log10.

I wonder if it is possible to confine the value which

method Nelder-Mead. Please give me some comments.
Thanks in advance!!

If x is the variable being optimized replace it with x = z^2 and
optimize over z. That will constraint x to be nonnegative.
