Dear colleagues, I just upgraded to 1.4.0 version from RH RPM on a RH72 linux i686 machine. Maybe I am the only one, but when I tried then to install 2 packages (namely pspline and xgobi), weird things happened. First on call of library(xgobi) or library(help=xgobi), all looks good, but on call of ?xgobi, or data(PaulKAI), or when trying to look at html help, the package seems empty. More

Very often when I print a data frame (particularly when sink()-ing to a file I do NOT want the row labels (which are in such cases usually 1, 2, ... nrow(x), where x is the data frame in question). I can of course edit these out ``by hand'', but that's a bit of a pain in the pohutukawa. I recently discovered (reading the help on print.data.frame meticulously, and following it through

Hi. I need a very short piece of help regarding colouring segments plotted on a graph. When I am plotting segments for the graph, I am using "red" and "darkgreen for the values "1" and "2" respectively. Heres the relevant line of code in R: + col = c("red", "darkgreen")[line.colour.value]) I just need to extend this to refer to a larger

Hi, I followed the following sequence of commands after installing 'XGobi': >library(xgobi); >data(ToothGrowth); >xgobi(ToothGrowth); I got the following warning message: C:/R13 1.0/rw1030/library/xgobi/scripts/xgobi.bat -vtitle 'ToothGrowth' -std mmx C:/DOCUME~1/h1452992/LOCALS 1/Temp/xgobi-TthGr5705 Warning message: argument `pkg' is deprecated.

R-help, Is there any package/function in R which can perform multi-dimensional scaling? Thank you in advance

Dear R-users and R-developpers, I've not been able to find 3d graphics in R, like Splus spin() or brush(). Are there any that I've missed and/or is anybody working on implementing these type of functions?

Dear R gurus, Below is a part of the R output. Please consider the two lines: > data > model.matrix(m1) Is there a way of suppressing the observation numbers 1, 2, ...27 in the output (I don't want these number to appear in the output)?

A student of mine wants to use R to do some nonmetric multidimensional scaling. According to the R FAQ, there's a package called pcurve that computes multidimensional scaling solutions, but I was not able to locate it the contrib page (I am a Windows user with R version 1.4.1). Can anyone tell me whether it is possible to do nonmetric multidimensional scaling with R, and if so, how? John

Hi I know this subject has been mentioned before but from the mail archives I'm under the impression that this is not possible ? I'm trying to carryout the equivalent of ls -l in R to give some date/time label to each of my objects If the case is that there is no equivalent, is it possible to list all objects in an environment that share a common component ? So that the common

This is just curiosity, but I'm wondering why the Morsecode app has remained part of the trunk for all of these years. Is there any practical use for this or is it just an homage to the ghosts of telecommunications past? Does anybody use the Morsecode app for anything interesting? I'm strangely fascinated by this core piece of Asterisk functionality. -Chris

Dear useRs, last week I asked you about a problem related to isoMDS. It turned out that in my case isoMDS was trapped. Nonetheless, I still have some problems with other data sets. Therefore I would like to know if anyone here has experience with how well isoMDS performs in comparison to other non-metric MDS routines, like Minissa. I have the feeling that for large data sets with a high

I wrote a little function called bgfun that adds gridlines and a background, but it's not working with I plot using the formula. I have some theories on what's happening, but even if my theory is right, I don't know how to fix it. Someone have a straightforward silver bullet? Thank you, Gene bgfun = function(color='honeydew2',linecolor='grey45',

Hi Folks, We can see these massages on our MDS Feb 12 12:46:08 mds01 kernel: LDISKFS-fs warning (device dm-0): empty_dir: bad directory (dir #31452569) - no `.'' or `..''

Do you have any idea how to

Hello! I need to perform weighted multidimensional scaling analysis(WMDS). I did rsitesearch, googled, but I could find no info on how to perform WMDS using R. In several places they say it is possible with the ALSCAL algorithm, but I could not find the relevant function to carry it out. ----------------------------------------------------------------- ???????? ?? ??????? ?? ??? ???????????!

Hi I used lustre-1.8.3 for Centos5.4. I patched the kernel according to Lustre 1.8 operations manual.pdf. I have a problem when I want to implement quota. My cluster configuration is: 1. one MGS/MDS host (with two devices: sda and sdb,respectively) with the following commands: 1) mkfs.lustre --mgs /dev/sda 2) mount -t lustre /dev/sda /mnt/mgt 3) mkfs.lustre --fsname=lustre

Hi, I need math function which is used in: isoMDS, Sammon and metaMDS method. Anybody know where I may find it? Any manual or webside?

Hi! I have a dissimilarity matrix X and try to compare it with X' = dist(cmdscsale(X,k)). If I increase k, I should expect that the error (or fit) should monotonically decrease, right. Here is a sample code; library(mva) set.seed(12345) x <- as.matrix(dist(matrix(rnorm(100),ncol=10,byrow=T))) # x[1,2]<-x[2,1]<-1000 ## <<--** 1 # x[5,6]<-x[6,5]<-1000 ##

i know cmdscale and isoMDS inR can do classical and non-metric MDS.but i want to konw if there is packages can carry on "individual differences scaling" and "multidimensional analysis og preference"?both method are important one,but i can not find any clue on how to do it using R. anyone can help? thank you!
