Dear R-users, The sasxport.get function (from the Hmisc package) automatically defines the class of imported variables. I have noticed that the class of theoretically numeric variables is simply "labelled", although character variables might end up been defined as "labelled" "Date" or "labelled" "factor". Is there a way to tell sasxport.get to

Dear R-users, I would like to know if there is a function (in base R or the extension packages) that would automatically detect the break points in a vector x for later use in the cut function. The idea is to determine the boundaries of the n intervals (n>=1) delimiting clusters of data points which could be considered "reasonably" close, given a numerical vector x with unknown

Dear R-users, In the R internals manual, it is said that one can extract the elements of the dot-dot-dot argument using the special symbols ..1 or ..2. It seems to work just fine but I was wondering if there is a way one can extract or modify the content of the dot-dot-dot argument using a level name instead of its position? For instance, assuming that list(...) returns: $a [1] 1 2 3 4 5

Dear R users, I am currently writing the documentation for my first package. I have created a short user manual using sweave/pdflatex which is distinct from the manual/summary-of-package-functions created by R CMD CHECK. I was wondering how could I seamlessly combine both documents. Thanks for your help Sebastien [[alternative HTML version deleted]]

Dear Listers I have tried to install Frank Harrell's two libaries: Hmisc and Design. I found that Hmisc was listed in the list of packages from the Install Packages command on the Packages menu, but Design was not. I installed Hmisc from this list, and when I issued the library(Hmisc) command, it loaded into memory correctly. I then copied the Design 1.1-1.zip file from the

Dear R-users, I am trying to port to R something that I wrote in Matlab to perform model parameter optimization using the Nelder-Mead simplex method (fminsearch). I read the help on ?optim (which seems to be the way to go) as well as a bunch of posts on the topic, but I would like to make sure about something before I spend to much time trying to reproduce something that is not possible. The

I'm looking for design and hmisc version 2.0 for R 1.8 for windows. I've found design 2.0 in the downloads for R1.7 but not hmisc. I've also checked Dr. Harrell's site and it only goes to 1.6 for windows. Any thoughts? Shawn Way

Dear All: I am working on writing some R functions to make statistical reports automatically. Dr. Harrell's Hmisc has all the wonderful stuff. But sometimes I need change some formats, so I want to read through it and make some modifications to fit my project. Ideally, I want proceed as following: 1. change some source of Hmisc 2. compile and install the modified Hmisc 3. debug my

Dear R-users, I would like to know how expressions could be passed as arguments to do.call functions. As illustrated in the short example below, concatenating lists objects and an expression creates an expression object, which is not an acceptable argument for do.call. Is there a way to avoid that? Thanks you Sebastien foo <- list(x=1:10, y=1:10) mylist <- list(pch=6, col=2) title

Dear R-users, I would need some advices on the proper way to call a particular function. This function is called scope.char and it is embedded in the step.gam function from the gam package. I am trying to call scope.char directly in a script but I did not find the proper way to do so. Is this even possible? If so, what is the proper syntax? Thank you for your time and help. Sebastien

Hi, Searching for functions that would order strings that mix characters and numbers in a "natural" way (ie, "a1 a2 a10" instead of "a1 a10 a2"), I found the mixedsort and mixedorder from the gtools package. Problems: 1- mixedorder does not work in a "do.call(mixedorder, mydataframe)" call like the order function does 2- gtools has not been updated in 2.5

Hi, The help page for subset states "subset: logical expression indicating elements or rows to keep: missing values are taken as false." Before I try to re-invent the wheel, I would like to know if one of the base or recommended packages would contain a variant of the subset function that would consider missing values as true. Thanks

Has anyone tried to download Hmisc and used ldBands function for calculating Lan-Demets group sequential boundaries? The write-up in F.Harrell's website indicates that, besides downloading the package Hmisc, one needs to copy the progra ld98 from the University of Wisconsin website. As suggested, I did this but received another error message regarding the search path. I think I have fixed

Dear R-users, I have got the following problem. I need to create 4x2 arrays of xyplot's on several pages. The plots are created within a loop and plotted using the print function. It seems that I cannot find the proper grid syntax with my viewports, and the more/newpage arguments. The following script is a simplification but hopefully will suffice to illustrate my problem. Any suggestion

Dear R-users, I am trying to understand what the different padding arguments in trellis.par.set are exactly controlling the space around lattice plots. I have used the following code as a basis for testing but it did not really help me to visualize how the value of each argument changes the margins and the plotting area. I guess a better way to visualize the effects of these padding items

Dear All, I'm reading Frank Harrell's wonderful Regression Modeling Strategies book and ran into a problem following the example in Chapter 8. I'm working on platform: Ubuntu 8.04 (i486-pc-linux-gnu) R version: 2.7.2 (2008-08-25) and my command sequence was: library(chron) library(Hmisc) load("prostate.sav") describe(prostate) The last command returned the error

1- mixedorder does not work in a "do.call(mixedorder, mydataframe)" call like the order function does This is tangential, but do.call(order, mydataframe) is not safe to use in a general purpose function either - you need to remove the names from the second argument: > d <- data.frame(method=c("New","New","Old","Old","Old"),

Dear R-users, I am trying to produce (standard and trellis) scatterplots which use the same range of the x and y axes. In addition, I would like the plots to be physically square. Is there one or more specific argument(s) to plot and xyplot what would do that? I have looked at various combinations of asp and pin value, but could not get what I wanted.. Thank you in advance for your help

Undoubtedly a simple question: I've looked at order() and sort() in the help pages for R1.7.1. It doesn't appear that these functions are immediately suited to doing the same thing as PROC SORT DATA = BLAH; BY X Y Z; RUN; in SAS. I have also checked Frank Harrell's Hmisc library. Could someone point me in the right direction so I can sort by the levels of Z within the levels of
