Getting rid of for loops
...or variable information. So I want to end up with a
dataframe at the end with the two variable names and the interaction p value
in each row, for all pairwise combinations of predictors. I used the
following code:
# qtl is the original data.frame, and my dependent var in this case is
# qtl$CPP.
marker1 <- NULL
marker2 <- NULL
p.interaction <- NULL
for ( i in 5:40) { # cols 5 - 41 are the predictor factors
for (j in (i+1):41) {
marker1 <- rbind(marker1,names(qtl)[i])
marker2 <- rbind(marker2,names(qtl)[j])
tmp2 <- summary(aov(tmp$CPP ~ tmp[,i] * tmp[,j]))[[1]]

multi-level cox ph with time-dependent covariates
...or outcome censored). Suppose that the pathogen can vary
over time (might be a bacteria that selects for drug-resistance) and
that also it can vary across different tissue reservoirs within the
same patient.
In other words: names(data) = patient_id, start_time, stop_time,
tissue_id, pathogen_type, marker1, ..., marker100, ..., outcome
If I had multiple observations per patient at different time
intervals, I would model it like this (hope it is correct)
model<-coxph(Surv(start_time,stop_time,outcome)~all_covariates+cluster(patient_id))
But now I have both the patient and the tissue, and hundred...

recoding a data in different way: please help
Dear R users
The following question looks simple but I have spend alot of time to solve
it. I would highly appeciate your help.
I have following dataset from family dataset :
Here we have individuals and their two parents and their marker scores
(marker1, marker2,....and so on). 0 means that their parent information not
available.
Individual Parent1 Parent2 mark1 mark2

ROCR for combination of markers
...ar list
I have 5 markers that can be used to detect an infection in combination. Could you please advise me how to use functions in ROCR/ other package to produce the ROC curve for a combination of markers?
I have used the following to get ROC statistics for each marker.
pred <- prediction(y$marker1, y$infectn)
perf <-performance(pred,"tpr","fpr")
plot(perf,ave="threshold",spread.estimate="boxplot")
But I want know whether we could get this for more than one marker, so we can look at how good the markers in combination to predict the infection. I'...

How do I assign boolean (o,1) values to a column?
Hi everybody!!
I'm trying to assign boolean values to a column in a matrix depending on the
number of times present in another column. I have no clue, I have been 2
days looking for a way, if somebody knows what kind of functions I need to
use I will really apreciate it.
example:
Color Type Mark1 Mark2 Mark3
Red high 139 P alpha
blue low 140 P alpha
Green high

Highlighting a few bars in a barplot
Hello,
I have a bar plot where I am already using colour to distinguish one set
of samples from another. I would also like to highlight a few of these
bars as ones that should be looked at in detail. I was thinking of
using hatching, but I can't work out how or if you can have a background
colour and hatching which is different between bars. Any suggestions on
how I should do this?
Thanks
