'data.frame' method for base::rep()
...gth [1] 1.4 $Petal.Width [1] 0.2 $Species [1] setosa Levels: setosa versicolor virginica $Sepal.Length [1] 5.1 $Sepal.Width [1] 3.5 $Petal.Length [1] 1.4 $Petal.Width [1] 0.2 $Species [1] setosa Levels: setosa versicolor virginica I found a 'rep.data.frame' function in package 'mefa' [2], but I think it would be nice to have it in base R. In any case, the code used by the method is very simple. > require(mefa) Loading required package: mefa mefa 3.2-1 2011-05-13 > mefa:::rep.data.frame function (x, ...) as.data.frame(lapply(x, rep, ...)) <environment: namespace:...

mefa 3.0-0
Dear R Community, I am pleased to announce that a new version of the mefa R package is available at the CRAN. mefa is a package for multivariate data handling in ecology and biogeography. It provides object classes to represent the data coded by samples, taxa and segments (i.e., subpopulations, repeated measures). It supports easy processing of the data along with relat...

Outer product from matrix by row and a vector
...e when applying the outer product with a matrix by rows. What I have is a rather big matrix, which I would like to convert into a different matrix by doing something like outer(matrix_row, vector, function(x,y) x[1]+5*x[4]/y) In order to get there, I tried to get the matrix into a list using the mefa package, as subsetting the original data appears too complicated. However, if I apply the following code I always get a dimensional error, as the unlist() function is applied to the whole list. library(mefa) a<-matrix(c(1:6),ncol=3) b<-c(1,2,3,4) a<-mat2list(a,MARGIN=1) outer(a,b,functio...

add label attribute to objects?
