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

I am wrestling with the following in creating a barplot in R: I have a data set with 18 entries. It is plotted in a bargraph. The x-axis should have 18 tick marks each with its own label. What happens is, only a few labels are shown; there is not enough space for all labels. The tick marks are concentrated on the left side of the axis. I'd like to have all labels shown, in vertical direction.

...r, tester$groups) # And want to keep only the first item in each: lapply(tester.L, function(x) x <- x[1,] ) How do i make a dataframe out of the last result, which looks like "tester", without looping? (i can use rbind in a for loop, but is rather slow) thanks for your help, Remko Duursma ____________________________________________________________ Get advanced SPAM filtering on Webmail or POP Mail ...

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

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

...tallation failed. But i set the path to MikTex, and "latex" as well as "pdftex" both run in the (Win) command window. I use R1.81 but also tried in R1.71. Any ideas?

Greetings, Last night I manually unpresented and deleted a LUN (a SAN snapshot) that was presented to one node in a four node RAC environment running OCFS2 v1.4.1-1. The system then rebooted with the following error: Oct 21 16:45:34 ausracdb03 kernel: (27,1):o2hb_write_timeout:166 ERROR: Heartbeat write timeout to device dm-24 after 120000 milliseconds Oct 21 16:45:34 ausracdb03 kernel:

...if (!is.null(naAct)) { data <- naAct(data) } however, the funcion na.exclude is not properly assigned to naAct in this way. Has anyone encountered this before? What to do? (i can, ofcourse, refit my model with excluding the NAs myself - but thats not so elegant!) Thanks, Remko Duursma ##################################### Remko A.

...ilable, otherwise "LOW" is reported. Are there ways of building a linear model with both fixed and random effects, when the response variable is censored? Can the tobit model be modified to do this? Does anyone have experience with this type of dataset?

Hi all, the option type="h" in plot() makes nice vertical (histogram-like) lines. Is there a way to make similar, horizontal lines? I can of course resort to using lines() multiple times, but i was hoping that there is a more elegant solution. thanks, Remko Duursma Ph.D. student Dept.
