Hello everyone, I mail you because of my lake of knowlegde regarding statistics. I'm using the CA and PCoA (but maybe should I use some other techniques) to determine the differences and similarities between a large sample of plants using different kind of traits through matrix of mixte variables. I understood that the daisy() function using the gower metric and defining the different type of variable is a good way to deal with such mixt variable. And in fact, my plots (cluster{agnes})(more that my PCoA) are quite reflecting what I was expecting from the aspect of those different...

...recirculée.en.continu These commands work perfectly when used individually and submitted directly. But when I am sourcing the command file including these lines, I get the following error message : Erreur dans parse(file, n = -1, NULL, "?") : erreur de syntaxe à la ligne 35: MES.liqueur.mixte.en.continu<- 1000*file_table[[2]]$MES.liqueur.mixte.en.continu 36: file_table[[2]]$MES.boue.recircul‚ I guess that the problem is coming form the "é" in my colnames as the following command : file_table[[2]]$MES.liqueur.mixte.autosurveillance<- 1000*file_table[[2]]$MES.liqueur...

I am trying to replicate the SAS proc univariate in R. I got most of the stats I needed for a by grouping in a data frame using: all1 <- ddply(all,"ACT_NAME", summarise, mean=mean(COUNTS), sd=sd(COUNTS), q25=quantile(COUNTS,.25),median=quantile(COUNTS,.50), q75=quantile(COUNTS,.75), q90=quantile(COUNTS,.90), q95=quantile(COUNTS,.95), q99=quantile(COUNTS,.99) )

I would like to call C routines from Fortran under linux as suggested in section 5.6 of the "Writing R extensions" documentation. I'm familiar with Fortran but not with C. I understand the example provided in Fortran: subroutine testit() double precision normrnd, x call rndstart() x = normrnd() call dblepr("X was", 5, x, 1) call rndend() end but I don't understand

Dear all, I am a relative newcomer to the R language, and am sussing out the possibilities of using R to do integer programming (which I am also new to). Is there something along the lines of the NUOPT S- PLUS package that is available, or on the way, for R? Are there other options for integer programming in R? Thanks very much in advance, Robin Naidoo University of Alberta Edmonton, AB,
