Hi, how can I get a more descriptive text instead of the variable names in my XY-lattice plot, according to the table below? Variable text acet = "Acetylaspartate Thalamus" chol = "Choline Thalamus" acetp = "Acetylaspartate parieoc" ino = "Inositole Thalamus" I could not find a solution. Please have a look at my syntax. Thanks a lot,

Consider > oj <- data.frame(x = c(TRUE, FALSE, NA)) > oj x 1 TRUE 2 FALSE 3 NA > summary(oj) x Mode :logical FALSE:1 TRUE :1 But > oj$x <- factor(oj$x) > summary(oj) x FALSE:1 TRUE :1 NA's :1 My point is that NA's should be reported for logicals like they are for other data types. Göran --- Göran

In the first line, use the dist function, found in library mva, to get the distance between each pair of rows. From this calculate an incidence matrix for which element i,j is true if row i in dat equals row j in dat (and false elsewhere). In the second line, for each row calculate the indices of the matching rows and take the minimum of those as the key. incid <-

Hi all, I'm looking at the mysql cdr backend to record call details, but I can't find any documentation on how to set up my database. Specifically, what is the table definition for the cdr table? I saw that the dbname, user and password can be set in cdr_mysql.conf, but there's no information on what table to use. Thanks, Gijsbert

Hi, [System info: R 1.6.1 compiled from source (no args to configure) on Redhat 7.1 Linux i/386] I have some spatial statistics programs that recently (since R 1.6.1) have generated SIGSEGV. These R programs use the splancs library as well as some C code of my own for Voronoi analysis. The program has a big loop to fit various model parameters against a spatial distribution of biological

R 1.6.0 has gone into final feature freeze as of today. As a new feature, we'll make interim beta versions available via ftp://cran.us.r-project.org/pub/R/src/base alias http://cran.us.r-project.org/src/base (filename R-1.6.0beta_*.tar.gz, where * is the creation date). If you want to help ensure that the final 1.6.0 works satisfactorily on *your* platform, it might be a good idea to

I've rolled up R-1.6.0.tgz a short while ago. This is a major upgrade, with several new features. A few of the changes generate compatibility issues. You may wish to consult http://developer.r-project.org/160update.txt. We no longer ship the set of recommended packages separately, but bundle them up with the main distribution. Thus there is now only a single file to fetch and (barring

Hi all, I have a problem with DTMF and SIP. When I dial an extension with 2 of the same digits in a row (ie '445', two 4s in a row), i have to wait at least one second between the digits. If I don't wait and just continue pressing digits only the first digit gets detected and the second (and third if there is any) is skipped. Everything works fine when there are none of the same

Hi I am running kernel 2.4.13 with ext3 support on an embedded system with 64 MB Flash and the .journal file takes size as 4 MB. Is it possible to minimize the .journal file ? With best regards/ Med venlig hilsen John Nørgaard

Hi! I was just wondering how Ext3 and Reiserfs compare. When I reinstalled my server (because of a stupid hacker) I took the opportunity to change to ReiserFS. And I have to say it's really much faster than Ext3. I don't have benchmarks, but for example, stuff like "make dep" on the linux kernel is much faster (even though I had enabled write cache when I was using ext3). So

Hi, Also I do have some problems mounting an ext3fs which gets just mounted as an ext2fs. (Yeap, I looked a little bit around in the mailling list and found similiar problems which haven't help me ;-( ) I have a root ( /) and a /mnt partition. both are converted via tune2fs -j into a journaled fs. my fstab looks like this: /dev/hda1 / ext2 defaults

Hello, I converted my / partition to ext3 from ext2 today, and I'm using kernel 2.4.13+ext3 patch I used tune2fs -j and set the filesystem to auto in fstab, and compiled ext2 as well as ext3 in the kernel Upon rebooting, I tried df -hT to see if it had worked, and to my surprise it didn't list my root partition dmesg say it's fine (and btw everything works fine) kjournald
