removing specific rows from array
I'm attempting to create an array of treatment comparisons for modelling data generation. This involves comparison of one treatment (c2) with another (c3), relative to a common comparator (c1).
Attached code gives me the correct array but need to remove duplicates. Duplicates relate only to c2 and c3
such that I need to remove
r3 because c2 and c3 are same as r1 with c2 and c3 swapped

Flexible rbind
Dear All,
I am trying to create a empty structure that I want to fill gradually
through the code.
I want to use something like rbind to create the basic structure first.
I am looking for a possibility to do an rbind where the columns names
dont match fully (but the missing columns can be defaulted to either
zero or n/a) (my actual data has a lot of columns).
Please see the data frames below

Calling library functions from outside R
I develop quite a bit of R code that I tend to distribute, or let
other people embed in their software. One of the things I'd really
like to do is find a way to load an R library I've developed, and call
one function with arguments.
Currently, I achieve that by building a separate R client file, which
reads in the command line arguments, loads the library, and calls the

Best IDE for R
Dear R-Group,
I am looking for suggestions for the "best" IDE for R. Best is obviously
subjective but I need just the basic features that should function well (and
I looked through the threads already).
- Proper integration with R 2.11.1
- Good key shortcuts ... similar to the R Gui
- Manageability of Projects, etc.
- Neat formatting features
I tried Revolution R but it seems huge in

data.table query
Hello Group,
I need a modification in the data.table example to get my intended
result shown below ... is there a more simple way!
dt <- data.table(A = rep(1:3, each=4), B = rep(1:4, each=3), C = rep(1:2, 6))
dt[, transform(.SD,D=mean(A)), by="B"]
The result I want is below ... which is probably long winded!

I want to find the positions (i.e. equivalent of nchar) for "cd" and
in case there are multiple hits .. then the results as a array

Parallel code runs slower!
My parallel code is running slower than my non-parallel code! Can someone
pls advise what am I doing wrong here?
t and tTA are simple matrices of equal dimensions.

nRows=nrow(t)
tTA = matrix(nrow=nRows,ncol=nCols)
require(TTR)

x = t[,i]
xROC = ROC(x)
tTA[,i]=xROC
}
)

R as a scripting engine
Those of you tracking R development will have noticed that we are
moving towards using R as a scripting engine. (It is often overlooked
as such.) Thus far INSTALL, REMOVE, SHLIB and massage-examples have
been moved to R.
Reasons:
- it is platform-independent and needs no other tools installed.
No need to worry about strange 'sh' variants (as on AIX and in the
past on Mac OS X)

Time Delay / Wait
Hi Group,
Is there something like a delay function based on System time or equivalent?
I basically am generating a few graphs and I would like to see each graph
for say 2mins before moving on to the next one?
I can always have an empty for-loop I guess but is there a better way?
Thanks,

Time out for a R Function
Hello Group,
I have an R-function that works fine for most part but sometime runs into a
long loop! (I'm lazy and short on time to debug right now so want to do
something easy)
For my purpose, it is ok to make few errors .... is there a way I can put a
timeout on a function and the r-process needes to move on to the next step?
Thank you.

Creating a list to store output objects from a recursive loop
Dear Group,
I am having a function that I am running in a loop that generated two
results for each loop
The result1 is a zoo object
The result2 is a data frame
Now I want to put both of them in a list or some structure ... that I can
access or output to a file after the loop is done.
For e.g.
for (i in 1:20){
niceFunction(x[i],i)
}
niceFunction (x,i) {
result1 = someOperations() #zoo

Print out data frames into neat images

I often need to print out data frames with results of analysis into a
neat little image to copy and paste into documents. I need apply

etc.

Any suggestions if there are packages to help with such activities (to
some level of basic functionality).

Drop matching lines from readLines
Dear R-group,
I have some noise in my text file (coding issues!) ... I imported a 200 MB
text file using readlines
Used grep to find the lines with the error?
What is the easiest way to drop those lines? I plan to write back the
"cleaned" data set to my base file.
Thanks.
