I found an other, less elegant, way as well. (This always happens, just
after asking someone else)

require(lattice)
png(filename=let's change the font.png, width=480, height=300,
pointsize=12)
xyplot(y~x,data=a,

It seems that this addition works, but has created just one object
called 'peak' with all the data from those 100 files. I'd like each
file to have a corresponding object containing the data.
Thanks for your help!

Hi R community,
I am trying to obtain a sample from a matrix but sample(my.matrix) doesn't
do what I need. I have a matrix of 1287 interactions between the species in
columns and the species in rows and I want to obtain a smaller matrix with
say, 800 interactions, that may or may not have the
Hi, my name is Marcel R. Lopes. My problem is,
I made a code to calculate the estimates of a Cox model with random effects.
Used to optimize the R command for this. The estimates were calculated
correctly, but the Hessian matrix does not have good values. The same thing
was done in SAS and gave

I am fitting logistic regression models, by defining my own link

gives a value for AIC, but I haven't been able to get R to convert
that to AICc. Is there a code that has already been written for
this? Right now I am
Dear R-Help,
I have a data frame and a vector
df=data.frame(Letter=c(Z,Q,R,A,E,F), Number=c(11,32,4,1,9,3))

From df, I'd like to construct a subset of the field Number, with
deletions dictated by the vector, v, of letters. I've succeeded in doing
this for a single deletion (for

I'm reposting this with a more appropriate subject.
Do I need to define limits as the error message seems to suggest? If so, how?
The error message, my code, the output and the first few lines of my data are

Thank you!

HI:
Is it possible to use the RODBC package within MS Access. I have been using
from R but was just wondering if it could be used along with R(D)COM. Something
like this:

Dim myApp As StatConnector

Hi James
its just simple calculus, since with

q10-qnorm(.1,me,sd)

sd-(q90-q10)/ (qnorm(.9)-qnorm(.1)) # between 10th and 90th are
qnorm(.9)-qnorm(.1)=2.563103sds

Dear R-users,
I would like to know if is it possible to set a function argument as an

following example, but could not get it anything to run. The plot

Are you using optim() function in R?
Although I am not sure what your problem really is (as you haven't provided
sufficient information), it may be that the hessian computation in optim()
is not accurate enough for you.
Try the function hessian() in the numDeriv package. It is very accurate.
