Hello, Recently, the following problem started happening with a particular samba server: If i have a file open for reading (say, a pdf in xpdf) and then try to write to it (say, through recompiling a latex document) it complains that it cannot open the file for writing. this seems like a file lock issue but I am unsure where it is happening. My previous usage should be perfectly safe since

text() can draw text on a plot. Do we have a way/function to draw text with a box surround it? Thanks, -james

Hi All, I tried combing through the archives, but I think that I just went mental. We're trying to set up a pxe server here using syslinux 2.0.6, and here's what we've got: client sends bootp request receives ip, server to go to and file to fetch. fetches and executes pxelinux.0 fetches pxelinux.cfg/default fetches display.msg (defined in default) displays the text - but when I

Pat Burns makes a good point. -Peter -------- Original Message -------- Subject: Re: [R] Using seq_len() vs 1:n Date: Fri, 12 Feb 2010 09:01:20 +0000 From: Patrick Burns <pburns at pburns.seanet.com> To: Peter Ehlers <ehlers at ucalgary.ca> References: <4B746AEF.10900 at ucalgary.ca> If you want your code to be compatible with S+, then 'seq_len' isn't going to work.

I have a new device that takes measurements anywhere from every second, to every 15 minutes (depending on changes). The matrix has a date, time and Y column (Y is the measurement). For three days it is 25,000 rows. How do I average the measurements by every 30 minutes so my matrix is 48 rows per day? I have been working on this and cannot figure out a simple method. Any ideas? Thank you. ----- In

Full_Name: John Abraham Version: rw1031 OS: Windows 2000 Professional Submission from: (NULL) (136.159.125.21) A friend introduced me to "R", and it seems just what I need -- a good statistical package with an open source flavour so that, if it doesn't do what I need it to do, I can extend it. I installed the latest windows binary, and when I try to run it I get a window

I would like to generate pseudo-random numbers between two numbers using R, up to a given distribution, for instance, rnorm. That is something like rnorm(HowMany,Min,Max,mean,sd) over rnorm(HowMany,mean,sd). I am wondering if dnorm(runif(HowMany, Min, Max), mean, sd) is good. Any idea? Thanks. -james

How can I add an overall plot title to these four plots? I would like to have something that says, "Distribution Comparisons": par(mfrow = c(2, 2)) # Plot 1 plot(rnorm(10),type="l",col="red") title(main = list(paste("Normal"), ????????????????????????? col="black", cex = 1.0)) # Plot 2 plot(rpois(10,

Folks: I know this may be overreaching, but are we missing what's important? WHY do the zeros occur? Are they values less then a known or unknown LOD? -- and/or is there positive mass on zero? In either case, using logs to calculate a geometric mean may not make sense. Paraphrasing Greg Snow, what is the scientific question? What is the model? Cheers, Bert On Mon, Jan 17, 2011 at 9:13 AM,

I would like to sum/mean/min a list of lists and numbers to return the related lists. -1+2*c(1,1,0)+2+c(-1,10,-1) returns c(2,13,0) but sum(1,2*c(1,1,0),2,c(-1,10,-1)) returns 15 not a list. Using the suggestions of Gabor Grothendieck, Reduce('+',list(-1,2*c(1,1,0),2,c(-1,10,-1))) returns what we want, c(2,13,0). However, it seems that this way does not work to mean/min. So, how to

I am wondering if you know how to return by function or show in boxplot, the indexes of unusual points, such as, points that are outside the box or in [Q3+1.5IQR,Max]. For example, > boxplot(c(4,rnorm(20),8)) There are 2 unusual points 4 and 8. How to show the indexes of 4 and 8 in the boxplot or return them by function? Thanks, -james

I need to find out what the maximum file size in an ext2/3 file system. It appears from the definition of the ext2_inode structure that since the i_size field is a 32 bit integer that the file would be limited by that. Thanks, Jason

Hi all, I am doing some intensive computation right now. My system is Pentium4 3.20G + 1.0G RAM + WindowsXP + R1.9.1. It seems my computer is very powerful. However, when I do some simple matrix algebra operations based on a matrix (DD) with dimension 5000000 by 2, I found that the consumption of RAM is huge. For example, the command a <- 1 - DD[,2] eats my 100M RAM. Does anyone know how

Dear Rexperts: (R 2.0.1 on Windows XP Pro) Is the following problem unique to my setup? If it's a known problem, I didn't see it at http://bugs.r-project.org/ nor find discussion in the archives. plot(1:10) loc <- c(5, 6) text(loc, labels = "a") Produces expected results according to ?xy.coords. plot(1:10) loc <- list(x = 5, y = 6) text(loc, labels = "a") No

Hi folks, I tried to use Mirosoft Fortran Powerstation 4.0 to create a dll file. However, when I used the command dyn.load(“test.dll”), I got the following message: NULL Warning message: DLL attempted to change FPU control word from 9001f to 90003 I read the instruction on Duncan Murdoch’s website about preserving registers, but I still don’t understand it. For example, 1. On first entry

Thanks, Writing plot(addTA()) worked fine. I find myself with such mixed feelings about R. After finding that addTA worked fine at the command line but not in a function, I puzzled for a long time about what kind of virtual machine structure could possibly account for that. I couldn't think of any. It turns out that this isn't due to an R virtual machine structure. The reason addTA adds

Hi, I wanted to add a few notes in the wiki on the fastestmirror plugin on how you can add exclude info in the fastestmirror.conf file. This became important because amazingly ucalgary.ca shows up as a fastestmirror for servers I have in both Nevada and New York. However, the mirror is horribly slow for actual downloads and frequently times out. So, I just want to add info on how to add the

HI: I have tried to find a way in which to export/save graphs via the command line. I know i can right click on it and save it as wmf etc. But I was wandering if there is a function such as Splus' export.graph Thanks >From Alberto Nettel's Desk University of Calgary Math & Stats Department.
