Hello list, I want to make a large rulebased algorithm, to provide decision support for drug prescriptions. I have defined the algorithm in a function, with a for loop and many if statements. The structure should be as follows: 1. Iterate over a list of drug names. For each drug: 2. Get some drug related data (external dataset). Row of a dataframe. 3. Check if adaptions should be made to

Hi all, I am doing nls regression of the Rogers type III equation. However I can't find good starting values and keep getting the error messages: "Missing value or an infinity produced when evaluating the model" OR "singular gradient matrix at initial parameter estimates" Is there a way to automatically check different starting values and give a list of values for each

Hi Could anybody please point me to some good links to draw Graphical charts using RubyOnRails and also suggest which is the best one?

Dear list, Could somebody who is more experienced with the Tcl/Tk interface from R please help me clarify the issues I've put below with ### --> tags? Several things go wrong, and it's probably because of messy code, but I have a difficult time finding out what is the cause. Thanks very much, JeeBee. require(tcltk) || stop("Package tcltk is not available.") # Add path to

I've searched the archives for an answer to this problem, and yet nothing that works seems to have been posted. I've seen it posted many times In my particular case, I'm running Samba 2.0.6 on Solaris 2.5.1, configured with the --with-smbwrapper, --with-automount, and --with-syslog options. I also have samba set up as a PDC, and that seems to be working fine. A stripped down

Dear Sir/Madam, I encounter some problem duuring compilation of R 1.9.1 on AIX 5.1, after running "./configure" then I type "make" to compile: # make ..... gcc -I../../src/extra/zlib -I../../src/extra/bzip2 -I../../src/extra/pcre -I. -I../../src/include -I../../src/include -I/usr/local/include -DHAVE_CONFIG_H -mno-fp-in-toc -g -O2 -c registration.c -o registration.o g77 -g

Hi, I have some blocked transactions. Does anybody have some advise on how I could mend this because I am unsure where to start? I believe this broke after I issued some set auth.allow commands: # gluster volume set oem-shared auth.allow 10.54.54.57,10.54.54.160,10.54.54.161,10.54.54.213,10.54.54.214,10.22.9.73,10.22.9.74 Kind regards, Sophie [2017-06-20 13:28:24.052623] E

Dear R-helpers, i have a question on how to vectorize this problem: i have a dataframe: tester <- data.frame(groups=c("A","A","B","B","C","C"), one=c(1,1,2,2,3,3), two=c(6,6,7,7,8,8)) # i split it into a list tester.L <- split(tester, tester$groups) # And want to keep only the first item in each: lapply(tester.L, function(x) x

Hello, * I am setting up a backup on a Linux system with Windows XP workstations. The backup goes to three alternating usb drives, each of which is NTFS formatted. The disks should be virtually identical but they do not seem to be. First, my mount command is this (I edited a bit for brevity) mount -t ntfs-3g -o locale=nl_NL.iso-8859-1,silent /dev/disk/by-id/usb-DiskA \ /mnt/tmp || mount -t

Hi Bob, Thanks for sending around the link to that. It looks mostly right and looks like a useful onramp. There are a few things to watch out for though (I've cc'ed Romain so he's aware of these comments). @romain I hope you taake the following comments as they are intended, as help rather than attacks. The largest issue I see is that the contract for Get_region is that it *populates

Dear R-helpers, Can someone explain to me why the function interaction() from the Hmisc library results in numeric? test1 <- c("A","B","C") test2 <- c("D","E","F") is.numeric(interaction(test1,test2)) [1] TRUE I had problems with this side effect in a different function. thanks, Remko Duursma

Dear R-helpers, i am trying to make a shared library from a Fortran subroutine, and i therefore used (after reading the documentation): Rcmd SHLIB forfile.f #(R1.70, Win2000) And the error is: " 'perl' is not recognized as an internal or external command,operable program or batch file." So i went ahead and tried to install Perl (from the suggested website in

I have a problem with samba 2.2.7a which is configured as a PDC for two Windows XP Profesional workstations. I'am working with roaming profiles for the winxp machines. My problem is, when I reboot a winxp machine my roaming profile becomes a local profile. When I don't reboot the winxp machine roaming stays roaming. This is my smb.conf configuration. The linux machine is a ConnecTUX

Dear R-helpers, i get some strange results using a linear mixed-effects model (lme), of the type: lme1 <- lme(y ~ x, random=~x|group, ...) For some datasets, i obtain very small standard deviations of the random effects. I compared these to standard deviations of the slope and intercept using a lmList approach. Of course, the SD from the lme is always smaller (shrinkage estimator), but in

Dear R-helpers, i want to draw a small plot (histogram) within a larger plot (simple scatterplot), so that the axes of the bigger plot remain intact. I know how to use layout() and par(mfrow...) and such, but I want the smaller graph to be *inside* the bigger plot. Is this possible? thanks, Remko

Hi all, recently, i tried making a package with my own functions - which worked fine, until i reinstalled MikTex (in Win2000). Now i get the error message: * checking for working latex ...

Dear R-helpers, for the purpose of plotting a dataframe, i am trying to sort a dataframe by one column, for example tester <- data.frame(one=c(3,2,1), two=c(2,3,1)) #> tester # one two #1 3 2 #2 2 3 #3 1 1 # I want to sort "tester" by column "one", so that i get a dataframe # that looks like: #one two #1 1 #2 3 #3 2 I know of 'sort' but

Dear R-helpers, i have the following situation: i have a bunch of y=b0 + b1*x from different studies, and want to estimate a "general" y=f(x). I only have the b0,b1's and R-squareds. Should i weigh the separate equations by their R-squared? thanks Remko ^'~,_,~'^'~,_,~'^'~,_,~'^'~,_,~'^'~,_,~'^'~,_,~' Remko Duursma, Ph.D. student

Hi, as I wrote before: I'm not able to connect a Windows XP Pro notebook to a Samba 3.0.4 server. All the other machines (most Windows XP Pro, but also a few Windows 2000 and Windows 98) can connect without any problem. This one machine is not part of the NT domain because it needs to connect 1 or 2 times a week only, and is on the road most of the time. The machine could connect
