dear all,
a simple question, I need to write a function in which I retrive an

I solved the problem thanks to this link

dear all,
I want to plot a kaplan Meier plot with the following functions, but I fail
to produce the plot I want:
library(survival)
tim <- (1:50)/6
ind <- runif(50)
ind[ind > 0.5] <- 1; ind[ind < 0.5] <- 0;

dear all,
I have a little problem I am doing a loop, witha grep function. sometimes it
happens that have the following results
> tmp <- grep("x", y)

integer(0)
how can I recognise this outcome? is.na is not working of course, so what
else?

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 li
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?

how can I overcome this problem? i
Dear all,
I am creating functions with the "three dot" strategy. I wold like to have
suggestion when writing multiple functions that calls multiple functions
with "...".
I will give you a couple of example:

>d=3:7
>example=function(x,y, z, ...){
plot(x,y, ...)
points(x,z, .
dear all,
I have a very simple question but I could not figure out.
I need to make plots with grid in the background.

plot(a,b, pch=20, xlim=c(0, round(max(a))), ylim=c(0, round(max(b

I am using Sweave to write my reports with R code. Unlucly my code take a

It seems that a sweave run does not save the enviroment at the end of the

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?
