similar to: Iterating over file lines

Dear R-help, I think I have kinda isolated the problem I had to the following: i <- 0 while( {i <- i + 1} < 5) { if(i < 3) next print(i) } This seems to go into an infinite loop. After I break the execution, i has the value 1. At the R prompt, if I start from i <- 0 and keep typing {i <- i + 1} < 5, it eventually evaluate to TRUE. So why does the while loop not work?

Prof. Tierney, Thanks very much for the info. Why does the loop work if I move the assignment out of the condition? E.g., the following works: i <- 0 while(i < 5) { i <- i + 1 if(i < 3) next print(i) } Regards, Andy > -----Original Message----- > From: Luke Tierney [mailto:luke at nokomis.stat.umn.edu] > Sent: Tuesday, October 02, 2001 3:36 PM > To: Liaw, Andy

Hi Everyone, I'm wondering if anyone here write AGI's in compiled binaries. I'm writing a small Cepstral AGI in Freepascal/Lazarus. I know there are some other AGI's out there, but I wanted to add some more functionality than what is available such as having the AGI determine if the "data" argument is plain text or a path to a text file and act accordingly. The

Prof. Gentleman (and R-help), Here's an example of what didn't work. I still don't understand why. Function: trycon <- function(file, n) { f.con <- file(file, open="rt") on.exit(close(f.con)) i <- 0 while( length(readln <- readLines(f.con, 1)) > 0 ) { x <- unlist(strsplit(readln, " ")) if(length(x) <= 6 && x[3] ==

Dear R-help, I have one more question about the functions mentioned in the subject. Again, the system info is: platform i386-pc-mingw32 arch x86 os Win32 (OK, it's NT4sp6) system x86, Win32 status major 1 minor 3.1 year 2001 month 08 day 31 language R

Hi, R users, I'm trying to transform a matrix A into B (see below). Anyone knows how to do it in R? Thanks. Matrix A (zone to zone travel time) zone z1 z2 z3 z1 0 2.9 4.3 z2 2.9 0 2.5 z3 4.3 2.5 0 B: from to time z1 z1 0 z1 z2 2.9 z1 z3 4.3 z2 z1 2.9 z2 z2 0 z2 z3 2.5 z3 z1 4.3 z3 z2 2.5 z3 z3 0 The real matrix I have is much larger, with more than 2000 zones. But I think it should

Hi, Is it possible to produce box-and-whisker plots given that I have the median, interquartile and 5/95th centile values, but not the data from which they come? It seems that it ought to be possible to coerce bxp to do what I want, but I can't quite see how.

Attempting to setup a dual ISP on a gentoo box but I''m not sure how to configure the routing in the /etc/conf.d/net configuration file. Does shorewall do all the routing or do I set just the default route to the PRIMARY outbound ISP?

Have a samba 3.0.22 joined ADS to a SBS windows 2003 R2. I am trying to get the SBS Backup to use a samba share. Username TPMMLAW\SBS Backup User is invalid on this system TPMMLAW is the domain. How would I map the "SBS Backup User" to a valid unix account. Any pointers? Vernon

FYI I will have an upload ready RSN. Where should I send it ? Matthew Vernon has offered to test my amd64 binaries. I will test the i386 packages myself. Ian.

Dear Bert and Huzefa, Apologies for the late reply, my account got hacked and I have just managed to recover it. Thank you very much for your replies and the solutions. Both work well. I was wondering if there was any way to ensure (force) that all possible combinations show up in the output. The full dataset has 25 cities but of course people have not moved from Boston to all the other 24

Hi, I have some data (lots of year,distance pairs), which I can straightforwardly boxplot: dists <- read.table("movedists.dat") with(dists,plot(as.factor(V1),V2)) If I want to plot these data as violin plots using vioplot, this approach doesn't work: > with(dists,vioplot(as.factor(V1),V2)) Error in Summary.factor(c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, : min not

Hi, You will be aware of https://weakdh.org/ by now, I presume; the take-home seems to be that 1024-bit DH primes might well be too weak. I'm wondering what (if anything!) you propose to do about this issue, and what Debian might do for our users? openssh already prefers ECDH, which must reduce the impact somewhat, although the main Windows client (PuTTY) doesn't support ECDH yet. But

I am mainly a Java/C++ programmer, so my mind is used to iterating over data with for loops. After a long break, I am trying to get back into the "R mindset", but I could not find a solution in the documentation for the applys, aggregate, or by. I have a data.frame where each row is an entry with 10 groups of measurements. The first measurement spans 1 column, the second spans 2

Hi, I tripped over the effects of commit 660854 [0] when moving some infrastructure from Debian 7 to 8 (openssh 6.0 to 6.7); our ansible module used "return 0, but no output" for 'host not found in known_hosts file', and now complains that ssh-keygen is returning an error status. I don't think this change in API was announced in the release notes? i.e. ssh-keygen -F

Hi, A bug I've had reported is that scp doesn't work with large files (Debian bug number 106809). The problem seems to be scp.c:504: if ((fd = open(name, O_RDONLY, 0)) < 0) Is there some reason why making that if ((fd = open(name, O_RDONLY|O_LARGEFILE, 0)) < 0) would break things? It seems a simple fix to me... Thanks, Matthew -- "At least you know where you are

Hello all, Sorry for the terribly newbie questions but I have successfully installed and access a home directory on my Linux box from a Windows XP server but am have trouble with write permissions to the folder. Any ideas on what could be wrong? Thanks Vernon

Hi, I've spent a while scrabbling around at this problem, to no avail. I'm sure there /should/ be a simple answer... I have a large (14 million rows) data set, with two columns. Each row contains the number of times an individual moved, and the distance that individual moved in total. I would like a figure where the colour indicates the density of points, rather like this one my
