merging dataframes
Dear List, I often have to merge two or more data frames containing unique row names but with some columns (names) common to the two data frames and some columns not common. This toy example will explain the kind of setup I am talking about: mat1 <- as.data.frame(matrix(rnorm(20), nrow = 5)) mat2 <- as.data.frame(matrix(rnorm(20), nrow = 4)) rownames(mat1) <- paste("site",

dovecot - 2 Faktor Auth
Hallo Liste, hat sich schon mal jemand mit 2 Faktor Auth f?r dovecot besch?ftigt? Es geht dabei nicht nur um die Absicherung einer Weboberfl?che sondern direkt die Absicherung der Standard pop/imap Verbindungen des Clients. Wir machen das auth bisher ?ber MySQL.? Rein technisch w?rde das gehen, da man die Password-Query beliebig anpassen und auch mit allow_nets arbeiten kann. Es w?re eher die

I cannot get species scores to plot with site scores in MDS when I use a distance matrix as input. Problems with NA's?
Hi, First I should note I am relatively new to R so I would appreciate answers that take this into account. I am trying to perform an MDS ordination using the function ?metaMDS? of the ?vegan? package. I want to ordinate species according to a set of functional traits. ?Species? here refers to ?sites? in traditional vegetation analyses while ?traits? here correspond to ?species? in such

R and TK Error "can't find objects"
Dear R People, I?m trying to link R and TK. I?m using R 2.11.1 with Tinn-R 1.17.2.4. For simple examples like the following one it?s working (see the initiation of the variables, the handler and the link to the function which multiply Zahl, Exponent and Factor) : require(tcltk) Ergebnis<-tclVar(c(0,0,0,0,0,0)) Zahl<-tclVar(c(0,0,1,1,1,0)) Exponent<-tclVar(c(1,1,1,1,1,1))

reading long matrix
Hi, I'm needing some help finding a function to read a large text file into an array in R. The data are essentially presence / absence / na data for many species and come as a grid with each species name (after two spaces) at the beginning of the matrix defining the map for that species. An excerpt could therefore be: SPECIES1 999001099 900110109 011101000 901100101 110100019 901110019

Scatter plot from tapply output, labels of data
Hei, i am trying to plot the means of two variables (d13C and d15N), by 2 grouping factors (Species and Year) that i obtained by the function tapply. I would like to plot with different colours according to the Year and show the "Species" as data labels. My data looks like this: Species d13C d13N Year "Species1" 14,4 11.5 2009 "Species2"

permutational Kolmogorov-Smirnov p-value for paired data
Dear List, I am new to R and find it very powerful. I would like to compute the permutational p-value for paired data using Kolmogorov-Smirnov, but the built-in ks.test does not have this option, unlike the t.test which has a paired=TRUE flag. Has someone written a library or a routine that does this? Alternatively, if someone could show me how to do pair-wise permutations in R, then I can

adonis help - (non-parametric (permutational) manova)
I am trying to apply this technique (M.J Anderson 2001) to a dataset of aquatic insect abundances. There is a sample in the unrestored and restored segement of a stream for every time period. I would like to compare the centroids of the distance matrices for the treatments up (unrestored) and dn (restored) to see if there is a difference in insect communities between the treatments.
