dear all,
a simple question, I need to write a function in which I retrive an
undetermined number of vector in the function.
I solved the problem thanks to this link

so my function will look alike this
dear all,
we am trying to improve the performance of my R code, with the implentation
of some function with custom C code.
we found difficult to import and export/import data structure such us
matrices or data.frame into the external C functions.
we already tried the solution from Writing R

Dear R users,
I have a simple problem I cannot solve, but I sure you can help.
I have two vector, let say
tmp1 - c(a, a, b, c)
tmp2 - c(a, a, b, c, c, d)
and I want to create a matrix of two column for which I have all the
combinations of the same character, let say like this
tmp3
Dear Bioc,
I am using the stat.diag.da function from sma package in R-2.7.0 to make
class prediction in microarray dataset.
I would like to retrive the not only the classification, but also the raw
score assigned to each sample in order to be classified both in the training
and in the validation
dear all,
I report a problem very simple, that I does non know how to handle.
look at the following code:
a = rep(16.256, 5)
sum(a[1:5]^2) - (sum(a[1:5])^2/5)
[1] 2.273737e-13
as you can see i retrieve a non 0 value, when i am expected to. what can I
do?
sessionInfo()
R version 2.6.2
dear all,
I am writing a sweave documentation for my analysis, and I am plotting huge
scatter plot data for microarray.
unlucly this take a lot of resource to my pc because of the quality of the

how can I overcome this problem?

}
dear all,
I have a very simple question but I could not figure out.
I need to make plots with grid in the background.
something like I old retrive like this
a=runif(100)*10
b=runif(100)*10
plot(a,b, pch=20, xlim=c(0, round(max(a))), ylim=c(0, round(max(b

Dear R user,
I am using Sweave to write my reports with R code. Unlucly my code take a
lot of time to run, and I don't want to run it multiple time, if possible,
as I am still developping the tools.
It seems that a sweave run does not save the enviroment at the end of the
process, is there a way

hi BioC,
I need to plot a vector of characters on a pdf device, not as a legend, but
as in image by itself.
I tried text but it is only related to locate text in a plot.
what do you suggest?
sessionInfo()
R version 2.6.0 (2007-10-03)
x86_64-unknown-linux-gnu
locale:
'put' data on your plot. What
else do you want?
