A problem subsetting a data frame
Hi all,
I have this microarray large microarray data set (ALL) from which I would like to subset or extract a set of data based on a factor ($mol.biol). I looked up some example of subsetting in, picked up two commands and tried both but I got error messages as follows
> testset <- subset(ALL, ALL$mol.biol %in% c("BCR/ABL","ALL1/AF4"))

Query in Cuminc - stratification
Hello everyone,
I am a very new user of R and I have a query about the cuminc function in the package cmprsk. In particular I would like to verify that I am interpreting the output correctly when we have a stratification variable.
Hypothetical example:
group : fair hair, dark hair
fstatus: 1=Relapse, 2=TRM, 0=censored
strata: sex (M or F)
Our data would be split into:
Fair, male,

Plotting question re. cuminc
Hello everyone,
(This is my second question posted today on the R list).
I am carrying out a competing risks analysis using the cuminc function...this takes the form:
cuminc(ftime,fstatus,group)
In my study, fstatus has 3 different causes of failure (1,2,3) there are also censored cases (0). "group" has two levels (0 and 1).
I therefore have 6 different cumulative incidence curves:

controlling axes in plot.cuminc (cmprsk library)
Dear R-help list members,
I am trying to create my own axes when plotting a cumulative incidence
curve using the plot.cuminc function in the CMPRSK library. The default
x-axis places tick marks and labels at 0, 20, 40, 60, and 80 (my data has
an upper limit of 96), whereas I want them at my own specified locations.
Here is my example code:

Survival Plot in R 2.10.0
I would like to produce a complimentary log-log survival plot with

Calculating Cumulative Incidence Function
Hello,
I have a problem regarding calculation of Cumulative Incidence Function.
The event of interest is failure of bone-marrow transplantation, which may
occur due to relapse or death in remission. The data set that I have
consists of- lifetime variable, two indicator variables-one for relapse and
one for death in remission, and the other variables are donor type (having
3 categories), disease

"order" issue
Hi everybody, this is a real dummy thing.
I sorted a matrix based on a given column, and what I get is right, until it comes to columns of negative and positive values; than, "order" orders everything from max to min in the negative values, and then AGAIN from max to min in the positive values!!!
Why isn't everything order from max to min, and that's it?
Thank you!!!

help on drawing right colors within a grouped xyplot (Lattice)
Hi,
I've lost my mind on it... I have to scatterplot two vectors, grouped by a third variable, with two different dimensions according to whether each cell line in the plot is sensitive or resistant to a given drug, and with a different color for each of 9 tissues of origin.

Cox model
Hello R-community,
It's been a week now that I am struggling with the implementation of a cox
model in R. I have 80 cancer patients, so 80 time measurements and 80
relapse or no measurements (respective to censor, 1 if relapsed over the
examined period, 0 if not). My microarray data contain around 18000 genes.
So I have the expressions of 18000 genes in each of the 80 tumors (matrix

discrepancies between stata and r for a cox regression
Hello
I would like to develop the use of R.
Trying R and more particulary the cox model, I am surprised by discrepancies between results with stata and R for a cox model
With the same data base, I get a hazard ratio (4.82) that is not the same obtained with stata (4.52)

putting the mark for censored time on 1-KM curve or competing risk curve
Hi All,
I'm trying to figure out the cumulative incidence curve in R in some
limited time. I found in package "cmprsk", the command "plot.cuminc" can
get this curve. But I noticed that there is no mark for the censored
time there, comparing with the KM curve by "plot.survfit". Here are my
codes (attached is the data):

Help on competing risk package cmprsk with time dependent covariate
Dear R users,
I d like to assess the effect of "treatment" covariate on a disease relapse risk with the package cmprsk.
However, the effect of this covariate on survival is time-dependent
(assessed with cox.zph): no significant effect during the first year of follow-up,
then after 1 year a favorable effect is observed on survival (step
function might be the correct way to say that ?).

Understanding of survfit.formula output
Dear list,
I am not familiar with survival analysis and I would need your help to
understand a result I have obtained.
I have used the following command line to look at number of events and
probability of survival at the first 5 years:
> su = summary(survfit(Surv(a[, Date], a[, Event]) ~ strata(a[,Prediction]),
data = a), times=c(0,1,2,3,4,5))
I have studied two kind of events (disease-free

error bars on survival curve
I am using plot(survfit(Surv(time,status) ~...) and would like to add
error bars rather than the confidence intervals. Am I able to do this
at specified times? e.g. when time = 20 & 40.
leukemia.surv <- survfit(Surv(time, status) ~ x, data = aml)
plot(leukemia.surv, lty = 2:3,xlim = c(0,50))

Stacked area chart and legends
I have found lots of good advice on this forum about stacked area charts but
I?ve run into problems with the 2 recommended options: stackploy in plotrix
or qplot in ggplot2. I have a many page report that will be in a 2x2 page
format ?par(mfrow=c(2,2))?? and need one of the page components to be a
stacked chart.
I?d prefer to use stackpoly, if possible, but I?m stuck on how to do the

cmprsk- another survival-depedent package causes R crash
Dear Prof Gray and everyone,
As our package developers discussed about incompatibility between Design and survival packages, I faced another problem with cmprsk- a survival dependent packacge.
The problem is exactly similar to what happened to the Design package that when I just started running cuminc function, R was suddenly closed.
These incidents suggest that maybe many other survival

consolidate three function into one
Hi Bert,
I am sorry to bother you on weekend.
I am still struggling on defining a correct function.
I first defined the function RFS (see below), then run it by provide the two argument.
m52.2cluster <-RFS(inputfile =allinfo_m52, N=2 )
I do not get error message, but no figure displays on screen. I do not know what is going on.
Can you help me a little more on this issue?
Thank you,

consolidate three function into one
FAQ 7.22
You must print a ggplot object, for example with
print(m52.2cluster)
For the FAQ, run the line
system.file("../../doc/FAQ")
in R on your computer.
Open up the resulting filepath in your favorite editor and scroll down to 7.22

Cox model+ROCR
Dear list,
I am trying to build a cox model and then perform ROC analysis in order to
retrieve some genes that are correlated with breast cancer. When I calculate
the hazard score taking into account different numbers of genes and their
coefficients ( I am trying to find the pest predictor number of genes), I
retrieve from around 1 values (for few genes included ) to size of e+80
values (for many
