Dear useRs, I am trying to fit a Cox PH model on survival data from a lung cancer dataset. I would like to include the patient staging (I-IV) as a covariate. For this I use the following function: coxph(Surv(time,status) ~ stage) The staging information is a categorical variable, and it is important to take the ordering into account (I<II<III<IV). Does the coxph function handle

Dear R-user, I am trying to use the function 'parLapply' from the 'snow' package which is supposed to work the same wys as 'lapply' but for a parallelized cluster of computers. The function I am trying to call in parallel is 'dudi.pca' (from the 'ade4' package) which performs principal component analyses. When I call this function on a list of

Thanks to Luke Tiernay and some experimenting I found out some issues. I don't claim this infomation is complete, but it may be helpful for anyone experimenting with SNOW on Linux: - environment variables PATH and R_SNOW_LIB need to be set on master and slaves. (manually or permanent in ~/.bashrc (adjust your pathnames accordingly). Don't use ~ for home directory, instead specify

I'm just curious if anyone else has had problems with this configuration. I added the CRAN repository to apt and installed 2.5.0 with apt-get. I then did an install.packages("Rmpi") on cluster nodes. Rmpi loads and lamhosts() shows the nodes, but mpi.spawn.Rslaves() fails (something to do with temp files?). Rmpi works fine with the Edgy-native version of R (2.3.x) and installing

Hello, I'm using R on a 10 blade dual quad core Rocks Cluster, and trying to use Rpmi and snow. I basically wondered if at the moment I ought to install Rmpi against another form of mpi (not openmpi) and wondered whether anyone could pass on any experience. I'm mainly worried about (a) the R server taking up 100% cpu time (I think this is a known issue with Rmpi and openmpi) and (b)

Hi, I have few high-level questions about the Snow and Rmpi packages . I understand that Snow uses Rmpi as one of possible transport layers, yet my questions about user experience, not technical details: 1. Does Snow install and work well in Windows? 2. Interruptibility. I understand that currently it is impossible to interrupt a running top-level command in Snow ( Ctl-c or the likes), the

Dear R Gurus: Is there a problem with Rmpi on x86 with SUSE 10.1, please? I've tried everything and it still won't load. Has anyone else dealt with this please? Thanks, Edna Bell

Dear listers I am a very newbie with graphs in R. I have a pulmonary function prediction equation in the form of PVC = 1.1 - 0.45*age in years + 0.011*height in cm. How can I draw the corresponding nomogram?. I read the help for the design.nomogram function but it is too difficult for me. Excuse my ignorance. Any direct help will be appreciated. Thanks in advance.

Hello, I am relatively new to R and am using it to run Classification and Regression Tree analysis. My only issue at this point is that numbers are always cut off on the lower nodes. I've tried changing the margins with mai=c(0, 0.5, 0.5, 0) but this has not so far worked. Any suggestions would be appreciated. Best, John Z. Metcalfe, M.D., M.P.H.

I am looking for a way to produce a "distribution graph" as in the example: (http://cecsweb.dartmouth.edu/release1.1/datatools/dgraph.php?year=2003&geotype=STD_HRR&event=A01_DIS&eventtype=UTIL Anybody who can help?

Dear Madam or Sir, I need to do multiple comparisons following nlme analysis (Compare the effects of different treatments on a response measured repeatedly over time; fixed = response ~ treat*time). On the web I found the notion that one might use the L argument from ANOVA. Do you have an example to show how this works together with nlme? Are there other ways to do a post-hoc analysis in

Hello, I am trying to compile sources of R-1.5.0 on a Mandrake 8.1 linux box. For Fortran compiler needs, I downloaded and installed a g77 rpm. But the configure step fails with following output. I would like to know if any of you had similar problem and how you solved. Thanks in advance.

Hello, I am currently trying to find an easy way to take a table with a mix of numbers and characters and format the numbers in the table to be constrained to 4 significant digits. Example: #this is my table creation > table <- matrix(c(12.34567, "--", 10, 12.34567, "--", "NA", "--", 123.45678, "--"), ncol = 3, byrow=TRUE) > > table

Hello, the package snow is not working on a windows cluster with MPICH2 and Rmpi.

Hello all, Can anybody tell me how to implement the heterogeneous bootstrap algorithm by the FEAR package. I only know there is a command (boot.sw98) for homogeneous bootstrap. Thanks a lot.

I have a dataframe with many rows like this: > df X1 X2 X3 X4 X5 X6 X7 week d sim1 FALSE TRUE TRUE TRUE TRUE TRUE TRUE 1 0.3064985 sim1 is the rowname, X1..X7,week,d are the column names. X1..X7 are factors, booleans in this case. I need to add another row, represented by the following list: list(rep(T,7),5,0.0) -- i.e, TRUE in all boolean columns,

Hi, i read something about MECOSA3 (G.Arminger) which is a software to : "Analysis of finite mixtures of conditional Lisrel models" I'm very interested to identify heterogeneous subpopulations and ask me are similar functions doing something in R, too ??? I know SEM and perhaps with some additions/modifications it is possible doing this general mean- and covariance structures with

Dear R-help: Does anyone know of a package in R that will do Welch's modified F-test for heterogeneous error variances? Are there other statistical techniques available in R that test the equality of means when homoscedastisity is violated? 't.test' does this in the pairwise sense when var.equal = TRUE. With best wishes and kind regards I am Sincerely, Corey A. Moffet Support

I have heterogeneous variance in a two-way mixed effects ANOVA, with more than 2 groups in each factor. Is there something like oneway.test or a Brown-Forsythe test that will let me test for differences in means? Thanks! -Keith
