...eed of subsetting to the fullest extent, in most cases only making a single copy of the data. * cast is replaced by two functions depending on the output type: `dcast` produces data frames, and `acast` produces matrices/arrays. * multidimensional margins are now possible: `grand_row` and `grand_col` have been dropped: now the name of the margin refers to the variable that has its value set to (all). * some features have been removed such as the `|` cast operator, and the ability to return multiple values from an aggregation function. I'm reasonably sure both these operations...

Hi, I'd like to get mean values for the margins of my casted data.frame. For the casting I am using dcast() from reshape2. However, when I set the margins parameter (margins=c("grand\_row")) I get following error concerning an unrecognized escape character '\_'. So what is the correct command to get the outermost margins only in reshape2? /johannes [[alternative HTML

Suppose I have data like this: A <- sample(letters[1:3], 1000, replace=TRUE) B <- sample(LETTERS[1:2], 1000, replace=TRUE) x <- rnorm(1000) I can get a table of means via tapply(x, list(A, B), mean) and I can add the marginal means to this using cbind/rbind: main <- tapply(x, list(A,B), mean) Amargin <- tapply(x, list(A), mean) Bmargin <- tapply(x, list(B), mean)

Apologies for troubling the list, but it is a test that needs to be carried out. I am resending the message that I sent earlier on behalf of Paul Miller, but with a certain word used in the variables names of the SAS code changed to a different word. With thanks for your tolerance ... Ted. [*** PLEASE NOTE: I am sending this message on behalf of Paul Miller: Paul Miller <pjmiller_57 at
