My opinion is that you should be spending your effort on setting up a SQL
engine and importing it there. If you have 32GB of RAM your current direction
might work, but working with sampled data rather than population data seems
pretty typical for statistical analysis.

What goes wrong? Your code isn't reproducible and you didn't give an

Hi everybody,
Thank you all for your suggestions, you have been very helpful.
However at the end I solved in this way:
mysample <- MaxDH[sample(1:nrow(MaxDH), 150, replace=FALSE),]
A<-mysample[1:120,]
B<-mysample[121:150,]
So simple at the end...
Best,
Luca

Thanks all, I realized the error of my ways last night. Apparently my
brain was on vacation yesterday. Thanks to all for going through this
yet again!

I thought this would be trivial, but I can't find a package or function
that does this.
I'm hoping someone can guide me to one.
Imagine a simple case with two survival curves (e.g. treatment &
control).
I just want to calculate the difference in KM estimates at a spec
Hi Kimmo,
Unfortunately, I can't visualize the attachment. Could you provide an example I

Please use dput() to give a reproducible example: I can make this work
on a data frame quite easily --
x <- data.frame(1:10, letters[1:10], rnorm(10))
str(x)
print(x)
x[sample(nrow(x), 5), ]
So it's not a problem with something being a data frame or having factors.

PLEASE do read the posting guide http://www.R-project.org/posting-guide.html

One way is to do it manually
plot(..., xaxt = "n")
axis(1, at = seq_along(wnd), labels = paste(seq_along(wnd), "h")
The other is to give plot x and y vectors.

dput(x.sub) so we can see what you really have.

Hi,
thank you, Pascal, for your quick reply. Unfortunately your suggestion
is not working. Please have a look on the attachment, I have added
manually the mean lines I am trying to plot. The problem with 'abilne'
seems to be that the argument 'v' is relative to the graph area, not the
x-axis
Ooops,
I forgot to specify that for each raw, containing records of the clinical
reports , the values of the 22 parameter measurement have to be reported.
For example, first raw, first 5 columns:
ID DATE GLICEMIA AZOTEMIA
CREATININEMIASODIEMIA ...
You don't provide either dput() or str() results, so nobody here knows exactly
what your data format is. But as a first guess, you should probably be using
sart<-x.sub$Time[1]
instead.

I wish to fit a dynamical model in R and I am running in a problem that
requires some of your wisdom to solve. For SAS users I am searching for
the equivalent of the */retain/ *statement.

I have a system of two equations written
Dear list members,
Within a loop, I need to create an xyplot with only a legend, not even
with the default external box drawn by lattice.
I already managed to remove the axis labels and tick marks, but I
couldn't find in the documentation of xyplot how to remove the
external box.
I would really
This question seems more suited to the Bioconductor mailing list:
you'll get specialized (and very good) help if you post there.
