Subsetting problem data, 2
Hello,
I didn't give enough information when I sent an query before, so I'm trying
again with a more detailed explanation:
In this data set, each patient has a different number of measured variables
(they represent tumors, so some people had 2 tumors, some had 5, etc). The
problem I have is that often in later cycles for a patient, tumors that
were originally measured are now missing (or a "new" tumor showed up). We
assume there are many different reasons for why a tumor would be measured
in one cycle and...

submitting R scripts with command_line_arguments to PBS HPC clusters
Dear all,
please could you advise me on the following : I've written a R script that
reads 3 arguments from the command line, i.e. :
" args <- commandArgs(TRUE)
TUMOR <- args[1]
GERMLINE <- args[2]

when I submit the R script to a PBS HPC scheduler, I do the following
(below), but ... I am getting an error message.

Hi all,
I got one problem with comparing strings like if any string is like
"*RIGHT, EPICARDIUM: FOCUS, GRAY-WHITE, SINGLE, APPROX 0.6 CM IN DIAMETER*."
and i have to compare "*GRAY-WHITE*" with the above string
or otherwise i have to compare " *TUMOR BENIGN*" this string
with
"*MEDULLRY TUMOR BENIGN,TYP PHEOCHROMOCYTOMA*"
i tried with split and compare but its not working
can any one suggest how can i compare these type of Strings
thanks in advance

Would you tell my how to extract a result from a test - it's justified because I need to run this test many times. Here is an example from authors' test:

How to load a big txt file
Dear list,
I need to read a big txt file (around 130Mb; 23800 rows and 49 columns)
for downstream clustering analysis.
I first used "Tumor <- read.table("Tumor.txt",header = TRUE,sep = "\t")"
but it took a long time and failed. However, it had no problem if I just put
data of 3 columns.
Is there any way which can load this big file?
Thanks for any suggestions!
Sincerely,

package to selelct diagnosis genes. The result seems not the same as I
expected.

select the best one using Maximum likelihood ratio test in logistic
regression model. This is the way my code works:
1. Read in 10 genes as independent variables and tumor type (1 or 0) as
dependent variable.
