Hello Is there an easy way, i.e. a function in a package, to calculate the area under the curve (AUC) for drug serum levels?

Dear list Maybe someone can help with the following problem: I have a source file containing the following code for plotting: pdf(file = 'data/mario/boxplot.pdf') bwplot(sig100 ~ target | group, data = fish, main = 'Boxplot der Signale in 100 Zellen nach Gruppe', xlab = '', ylab = 'Anzahl der Signale') dev.off() pdf(file = 'data/mario/xyplot.pdf')

Dear WizaRds, This is mostly a statistics question, but I'm figuring that R is the right solution (even before I start!) I have some bio data of heart rate versus time (rats taken from resting to maximal heart rate). I want to regress heart rate on time. The data have been normalized such that resting heart rate is zero at time=0, so that all curves intersect at the origin (and at the origin

Hello, Peter, I tried it out: iconv(names(attributes(spss[,'Y6'])[[1]][14]), "UTF-8", "LATIN1", sub='byte') yielded [1] "<c4>rzte Chirurgie" and c4 corresponds in most encodings to ?. What can I do next? I wonder whether there is a more comfortable way then to change the occurences of <..> by the adequate character. Regards, Matthias

Hi list, I want to use the p-value from the survdiff function (package survival) to reuse within a function in a Kaplan-Meier plot. The p-value is somehow not a component of the value list ?! Thanks in advance -- A. Goralczyk G?ttingen, Ger.

I couldn't find out how the following to solve: There is a column in a data.frame: > d[, 'Y6'] [1] 6 3 8 11 8 9 6 8 3 5 10 15 NA 9 8 3 8 16 6 6 NA 10 5 2 7 7 6 16 7 15 7 10 12 8 7 12 12 16 7 6 8 8 15 6 [45] NA 8 99 7 12 8 9 16 7 16 8 7 7 1 15 12 8 7 10 7 8 7 8 9 8 6 6 8 6 16 11 5 11 11 1 11 3 7 7 10 10 10 6 11 [89] 16 NA

Dear group, I have noticed that the MacOS X binary for lme4 is not available on CRAN at the moment. I am aware that it may be possible to install from source but I am not very familiar with that procedure and would rather avoid it. But I need the package for a statistics course next week. So can anybody give an update about the situation with the MacOS X binaries? Will it be resolved within the

Hello (R-)Experts I hope someone can help with this problem concerning axis annotation of a lattice shingle plot. I want a plot with three shingles to display some laboratory value over time. In the first panel over the first few days, then in the next panel some months, and in the last panel some years. In the following minimal example the axis annotation will be in days, but I'd like to

Hello all I would like to visualize the hazard ratios of a cox proportional hazards model. I have seen some good examples in the New England Journal of Medicine: http://content.nejm.org/cgi/content/short/353/26/2747/F3 http://content.nejm.org/cgi/content/short/350/26/2654/F2 (I hope these are open access, but I am not sure) And something similar in the book 'R Graphics' by Paul

Hi list I tried to install package lattice on FreeBSD, but install.package() does not seem to find it in the repositories, even trying different mirrors.

Hi list Maybe someone can help with the following problem (thanks in advance): In a function I have a plot and want to add symbols/text only when indicated by a logical vector (which was generated by the function before, not manually like in the following example): plot(1:10, 1:10) lv <- c(T,T,T,F,F,F,T,T,T,F) text(1:10, 1:10, '*', pos = 3) In this example the asterisk is plotted at

Hi guys, I'm been following samba for six or seven odd months now in preparation for moving our organisation over to a file server which is a little more cost effective than the Micro$oft alternative. We are currently running with about 30 users on a Windows 2000 Small Business Server. Do you see any problems in replacing this server with a linux box running Samba? Is the file

My Dell server was preloaded with Redhat 7.2 , Linux 2.4.7-10, gccv2.96 with Ext3 file system.

There are now several R geographic user groups, and a few have mailing lists on the R mailing list system. Thanks to Martin M, there's also a pointer to a page I'm maintaining to list/describe the groups. The page is at http://macnash.telfer.uottawa.ca/RUG.html Contact me if you have a listing. I'm prepared to wikify it if there is sufficient interest. John Nash

Hi, I would like to know, what's the importance of sid and rid, for: 1) a win2k to samba migration, with roaming profiles 2) brand new domain on samba, with roaming profiles If rid and sid need to be migrated to a samba+ldap how do I do it? Another thing is, I've read in ldap-smb-HEAD-howto.html that the builtin accounts are implemented internally in the samba server. Does this mean I
