Hi For bureaucratic reasons beyond my control I need to rewrite an R function (for producing operating characteristic curves) as an Splus function ( version 6 , windows XP ). The R function makes extensive use of the fact that the student's t distribution function pt() has a non-centrality parameter built in ... sadly that parameter is not present in the Splus pt() function .

hi Andrew Many thanks for the suggestion. I gave it a try , but still get the same issue - a fresh Rgui window (just one) opens, with an empty .RData, when I submit a script ( Ctrl & F8 ). I also tried running things as administrator, but it made no difference. Apparently windows 7 is selling like hot buns, so there should be enough market pressure before too long , to encourage the

[my original message to s-news & r-help is attached ] No one possessed or knew of any S/R code for the sequential t-test. Also it doesn't appear in the SAS index. One or two suggested obtaining the S+ seqtrial software which may (or may not) cover this, but this seemed to be a bit of a "hammer to crack a nut". I have written a function based on the treatment in Wetheril

something like ... > x<-c(1,2,3,0,5,6,0) > is.na(x[x==0])<-T > x [1] 1 2 3 NA 5 6 NA ~~~~~~~~~~~~~~~~ Robert Kinley ~~~~~~~~~~~~~~~~ [[alternative HTML version deleted]]

We (Eli Lilly & co) have a vacancy for an experienced industrial statistician who is familiar with mainstream statistical software, particularly Splus (or R) and/or SAS and/or JMP. The role is to provide expertise and training in Statistics in support of process-improvement in all areas of the business, particularly Statistical Process Control, Design of Experiments, and Quality

I really like RStudio ... ... but I wish it wouldn't automatically reload the last .RData it had. Anyone know how to fix this ... ? Also - does anyone know is there an Rstudio-user email-list forum thingy out there ? ta. Robert Kinley [[alternative HTML version deleted]]

Does anyone have, or know of, some S or R code to implement the sequential t-test ? The test is outlined in Kendall & Stuart vol 2A, ch 24, and a 'how to do it' with a set of tables is given in 'Design & Analysis of Industrial Experiments' ( O.L.Davies). I'm interested in obtaining/creating an Splus or R application which calculates the upper and lower curves

My small brain is having trouble getting to grips with lme() I wonder if anyone can help me correctly set the random = argument to lme() for this kind of setup with (I think) 9 variance/covariance components ...

hi I've used R for many years on windows machines, but have now acquired an Asus eee 1000 linux machine. In order to get the best out of the machine, I used the 'pimpmyeee.sh' script, to get the full KDE desktop. The version of Linux is Xandros, which I believe is a close relative of Debian, but sadly I have only a nodding acquaintance with Linux at present. Naturally I want to

It's often useful to view objects in time order. In Splus I can do this with > objects.summary(order = "dataset.date") which delivers this sort of thing ... data.class storage.mode extent object.size dataset.date reference data.frame list 25 x 4 1700 2004.09.13 15:43 x data.frame list 15 x 4 1175

platform: R 2.14.2 - Windows XP - Rstudio When I use cat() or print() in a script, the output text is of course mixed up with the lines of the script. I can sink() the output to a textfile and then play the file back at the end of the script, but that's not really what I'm after. It would be nice if the lines of text output could appear in a separate window, in the same

Hi I'm having difficulty working out how to get what I think is the appropriate partitioning of variability in a repeated measures setup. I have G=5 treatment-groups, each containing n=6 subjects, and a response is measured on each subject on t=4 occasions. I think the anova degrees of freedom should partition as follows - Between-subjects: G*n-1=29 [ between-groups: g-1 = 4 ,

Hi does anyone know of any R functions or packages for the following :- . generating cube plots for displaying the results from a response surface experiment design . generating ternary plots from a mixture design . tetrahedral plot or quaternary plot for displaying results from a four factor mixture experiment thanks Bob Kinley [[alternative HTML version deleted]]

Hi, This is not an R question, but can anyone please point me to C/Fortran (C preferred) code which calculates the non-central t-density or the cdf? Many thanks and best wishes! GT

Hi folks I have inherited a package which was created before release 2.10 and I need to have it working in release 2.12 There is a folder containing the Man, Data and R subfolders, and the description file, and there is also the corresponding zip file. I can install the package from the zip file, but when I try to load it I get the message :- Error: package was built before R

{ I think this message got rejected at the 1st attempt - trying again} R 2.15.1 , windows XP I have a very non-stationary bivariate time-series - say {xt,yt} t=1 ... lots. I want to do a bivariate density contour-plot of the whole series and then step through the series 1 second at a time plotting that second's {x,y} subset on top of the contour plot and losing the previous

First I'd like to remind people that I am publishing RHEL 7.3 preview packages of libguestfs here: https://people.redhat.com/~rjones/libguestfs-RHEL-7.3-preview/ https://www.redhat.com/archives/libguestfs/2015-September/msg00079.html These can be installed on RHEL 7.2. In the libguestfs-1.32.1-3.el7 package that I have just uploaded, I have enabled *experimental* support for virt-v2v

this is a clearer (I hope) version of an earlier post - My problem is formulating the random = argument to give estimates of all 9 random components for this kind of setup where there are (I think) 9 variance/covariance components ...

Hai, NfsV4 and samba works fine but there is a big BUT and you have found it already. > The nfs4 krb5 export mounts on the remote client, but doesn't seem to > recognize permissions. The mount directory is shown as owned by root and the group is 4294967294 Yes, the nfsv4 acls and system acl over kerberos doent match anymore. This is a know problem and i dont know when it wil be
