similar to: Searching for antilog function

Hi, I am using R for microarray data anlaysis. When I normalize my data, it converts all my data in to log base 2 values. how can I convert back to log base 10..is there any function in R which I can use or how can I take anti log. or is there any function in R for antilog. Please let me know,..if anyone knows.. Thank you so much, Saurin ===== Saurin's WebWorld:

Dear R gurus, I want to wrap labels that are too long for a plot. I have looked at strsplit(), substr(), nchar(), and strwrap(). I think it's some combination but I'm having difficulty trying to figure out the right combo. I think I need to create some new matrix containing the labels already split, though I'm not sure if maybe there is a quick and dirty way to address this

Hello. I am an R newbie struggling to learn and use R . I have read many portions of the R Reference Manual, as well as the FAQs. Given that I learn something new each time, I know I might be missing something obvious. But I appeal to your good nature to help me through this initial problem. I have attached a pdf file to demonstrate what I desire and have listed what my data looks like in

So I'm working from home today, and for the first time I've tried running Evolution over a forwarded X11 connection. Even though work has a T1 and I have 640k at home, and ssh is compressing, it's ... rather slow. So I fire off lbxproxy and try to run an xterm to see if it works. No dice, authentication denied. Does anybody have any experience with this? Is it possible to run

I would like to put a patch in OpenSSH start lbxproxy on the server if both ends of the connection support LBX. I'm having difficulty figuring out where to put this code, specifically I can't seem to find where the X11 handshaking happens. Could someone help me out on this?? -Carl

Hello, I use rsync (among many other things) as an incremental backup tool. Every night I save /{home,etc,var} from several servers. On one of them we keep 52 weeks of system logs, so each time syslog is rotated all old syslog.x.gz (where x is between 1 and 213) change names. This impacts our backup transfers because the incremental snapshot now has to include all syslog.x.gz files even though

Hello, I use rsync in the company to make a backup every 4 hours. but I would like to do in a way like this, that the rsync make a backup of the changed files until one month long. EX:- file.bak.001 file.bak.002 ..... This file will be to get always, and so i can get the all files untill an one month old version of the file. Is it possible? Regardes Dipl.-Ing. Nazar Hassan

Hi German users, Can one of you guys give me a German Phrase that I can use to demonstrate tokenizing non-ascii text. Preferably something about 40 bytes long with lots of umlauts and perhaps a ?. Cheers, Dave

We had been using R1.2.3 "print tip lowess function" as described by Terry Speed's group to normalize microarray data and up until this week the commands we were using were working fine. First, we load our data using arrayname<-read.table("filename", header=T) and then check that the table is OK. We format the data list using setup1<-init.data() and usually get a

Hello, ** Please reply directly to ian@ichilton.co.uk ** Does anyone use PDQ for printing with Samba? If so, please could you tell me what options to use in smb.conf?? Mainly, what do I use for the printing option? Can I just use: printing = bsd print command = pdq -P%p %s; rm %s Or, can I not use PDQ, because there is no setting for it on the printing parameter??? Thanks! Bye for Now,

Hi, I ve had some problems printing from NT, I had samba 2.0.3 and every time at the end of document there is a blank paper and I don't know how I can stop this ??? Regards, and thanks in advance for any help Amin.

This bug is not quite fixed - the example from my original report now = works using R-2.2.1, but plot(Uniform, 6) does not. The bug is due to if (show[6]) { ymx <- max(cook, na.rm =3D TRUE) * 1.025 g <- hatval/(1 - hatval) # Potential division by zero here # plot(g, cook, xlim =3D c(0, max(g)), ylim =3D c(0, ymx),=20 main =3D main, xlab =3D

Dear Sir/Madam, I could succesfully normalise my microarray data using marrayNorm package. However, i have not been able to get normalised red and green channel intensities through R package. Is there a possibility to write a formula to calculate back the red and green channel intensities after normalisation of the data. Do I need to incorporate this formula in my R script? I am biologist

I read the following hint at: http://www.mikerubel.org/computers/rsync_snapshots/#Incremental mv backup.0 backup.1 rsync -a --delete --link-dest=../backup.1 source_directory/ backup.0/ I simply want to maintain a dated backup of a server so that I could always go back to a certain date. I would like to keep this structure for each day for the last seven days, then one weekly snapshot for

Hello all, I am wondering if it would be possible to write a script or a cronjob in linux using Rsync to run an automated backup of a server, or serveral servers if possible. I am very new with writing scripts and such, so any help or suggestions with how to get started would be great!!! Thanks ahead of time for the help!!! ----- Computers are like air conditioners.

Dear R users, according the help(log), the function log2(x) should give the natural logarithm of x. I expect in case of x=2 to to get 0.6931, however, R gives me 1 as a result. Similar, logb(2,2) gives 1 again. I'm wondering if I have missed something ?

Does anyone know R is to be cited in a publication? I've looked everywhere on the website and cannot find this.

Hi, As I'm pretty new to R I hope this question isn't too basic. I am currently looping through my dataset and for each iteration am producing three separate plots. When I output these plots to the screen they are nicely grouped as three plots per page, however, when I try to send it to a PostScript file I get one page for each plot. I have adjusted my postscript options so that my

Hi, I am running an analysis with an ordinal outcome and I need to run a test of the parallel regression assumption to determine if ordinal logistic regression is appropriate. I cannot find a function to conduct such a test. >From searching various message boards I have seen a few useRs ask this same question without a definitive answer - and I came across a thread that indicated there is no
