[R] competing risk p value in a figure
Dear R users Is there a way to include in a figure the 2 sided p value obtained with the crr function in the package cmprsk Such as the one for cuminc: text(3.5,0.05, adj=0, paste(Gray test: p-value = , round(fit1$Tests[1,2],3))) thanks for your help ?

[R] detection of outliers
Hi, this is both a statistical and a R question... what would the best way / test to detect an outlier value among a series of 10 to 30 values ? for instance if we have the following dataset: 10,11,12,15,20,22,25,30,500 I d like to have a way to identify the last data as an outlier (only one direction). One way would be to calculate abs(mean - median) and if elevated (to what extent ?) delete the extreme data then redo.. but is it valid to do so with so few data ? is the (trimmed mean - mean) more efficient ? if so, what would be the maximal tolerable value to use as a threshold ? (I guess it will be experiment dependent...) tests for skweness will probably required a larger dataset ? any suggestions are very welcome ! thanks for your help Philippe Guardiola, MD __ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
[R] survival analysis question
Dear R users, I have survival estimates for 2 groups according to a factorial covariate (covar=1 or 2) and I d like to only plot the difference in term of survival between these 2 groups over time with 95%CI. Could someone send me a short script to do that since I m not an old R programmer ? thanks Philippe [[alternative HTML version deleted]] __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
[R] menuRandomSample funciton in S+ - R?
Hi all I cannot find the menuRandomSample function, which is available in S+, in R. Does it exist in R ? If so, what is its name ?

[R] survival analysis question
Hi, I m studying the effect of a binary covariate on the time to an event, ie, patient requiring treatment. It clearly appears that this covariate has an effect during the first year of life but not anymore thereafter. I d like to know until what age this covariate has a significant impact on the endpoint of interest, knowing that there is a competing risk here since the patient can also die during the time of study. What would be the best option to do so ? Said in a different way, what I think is that when this covariate is = 1 the risk of requiring a treatment is increased as compared with patients who have this covariate = 0 by 4, 5, 6, 7, 8 years of age but after there is no more impact of this covariate since they will all receive a treatment. The idea is to be able to say, if covariate = 0 then the risk of requiring a treatment until 8 years is lower than if the covariate = 1; and I d like to be able to say until when this risk in significantly increased. Hope I m clear ! thanks for your help Philippe __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
[R] Source package installation for WinXPpro
Hi I d like to compile the source code from last Affy package for WinXPpro under R18beta however the doc is pretty poor regarding this process... I went to FAQ R Win then to http://www.stats.ox.ac.uk/pub/Rtools/ and downloaded in The essentials, tools and Perl 5.8.0, then MingW from www.mingw.org and I wonder if I need any other stuff from this page ? I m not sure but I dont think I need the cross-conpilers ? what about the others below ? Then I installed MingW and Perl. Then what am i suposed to do? If I click on Rcmd I dont get any windows to open or just for a second... thanks for your help Philippe [[alternative HTML version deleted]] __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
[R] Problem with R1.8beta
Hi, I trying to use r.180beta on a XPPro PC with Athlon 2.0 I downloaded the zip file and when I unzipped it using winzip last version I had this message: C:\Program Files\R\rw1080beta\doc\manual\refman.pdf An error occured while trying to copy a file: The source file is corrupted. Anything to do with this or shall I just skip it ? thanks Philippe G [[alternative HTML version deleted]] __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
[R] in addition R1.8b install
this problem also occurred later in the installation process: C:\Program Files\R\rw1080beta\doc\manual\refman.pdf C:\Program Files\R\rw1080beta\library\mva\html\loadings.html C:\Program Files\R\rw1080beta\library\ctest\html\fisher.test.html C:\Program Files\R\rw1080beta\library\base\chtml\base.chm C:\Program Files\R\rw1080beta\afm\hvo.afm An error occured while trying to copy a file: The source file is corrupted. however by the end R opened correctly any suggestions ? thanks Philippe [[alternative HTML version deleted]] __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
