Getting rows from a dataframe
Sorry if this is a silly question. I'm trying to extract all elements of a dataframe at a particular row. I can find no mention of this in any documentation and it may be naivety of dataframe on my part as I'm very green at this. Thankyou, Mark

BATCH and tcltk
Hi R-hackers I try to write a batch (in Windows, i have to use!) with Rcmd BATCH D:\Test.R D:\Test.Rout and Rterm.exe --no-restore --no-save < D:\Test.R > D:\Test.Rout. In my file Test.R are any tk-codelines (like: Window1 <- tktoplevel(); ... tkbutton...). It works not interactifly, what is written in Rcmd BATCH --help. Exist there a way to do it all the same? Please help...

Hi everyone! Thank you for the help you have been given to me, and here I'm with another problem with my dataframes: I have two dataframes (with much more observations), like these: Dataframe1 Firm Year cash 500400200 2007 100 500400200 2006 200 500400200 2005 400 500400300 2007 300 500400300 2006 240 500400300 2005 120 500400400

proper way to process dataframe by rows
This is a best practices / style question. The way I use RODBC is I something like this: > foo <- sqlQuery(db, "select * from foo") > apply(foo, 1, function{...}) That is, I use apply to iterate over each result -- row -- in the RODBC-produced dataframe. Is this how one generally wants to do this? My concern is that when apply iterates over the rows, it uses as.matrix()

functions and getting them into R
Dear All, I am new to R and can see it is a very powerful and versatile system for programming and statistical analysis. Say I have written a simple function and want to use it on a regular basis. I have the file as a text file say 'c:\R-funcs\func.txt' how do I get R to find it on the hard disc or alternatively where is the default location for looking up functions where I can place

Rows not common in dataframes
Hi, I have two dataframes (Dataframe_A, Dataframe_B) with the same no. of columns. The first column of both the dataframes contains unique names. I wish to have Dataframe_A with the rows that are NOT common to Dataframe_B. With merge (), it is possible to get the common rows or to merge rows, but I am not quite sure how to do it in a simpler way. Any help would be much appreciated. Thank you.

Streaming Speex over RTP
I am a brand new user of Speex, so forgive my naivety. I am receiving an audio stream (PCM) which I need to encode in Speex, send it across a wire via RTP, and then decode and play the audio on the other side. I assume people have done this before, and I was wondering if anyone had any sample code of how they accomplished this. Or maybe just some good pointers or advice. Thanks Shane

REML with random slopes and random intercepts giving strange results
Hi everyone, I have been using REML to derive intercepts and coeficients for each individual in a growth study. So the code is m2 <- lmer(change.wt ~ newwt+(newwt|id), data = grow) Calling coef(model.lmer) gives a matrix with this information which is what I want. However, as a test I looked at each individual on its own and used a simple linear regression to obtain the same information, then

AW: Query: IRR Confidence Intervals
Hi Cristian, I don't know about a R routine for exact CIs, but I found a function called "ageadjust" using a gamma distribution approximation some time ago -take a look at http://medepi.org/epitools/rfunctions/index.html. That Webpage seems a bit outdated now, but the calculations given in the ageadjust functions should still work, I think. Maybe this helps; regards Heinrich.
