Hi all. I'am sitting for hours. I have a problem labelling arrays. I am loosing labels for higher dimensions than matrices. Has anyone already faced that problem? There must be some direct way without writing complicated functions. Thanks for any hint. greetings lars x<-matrix(sin(1:90),nrow=100,ncol=9) dimnames(x)[[2]]<-c("F1_5", "F2_5", "F3_5","F4_5", "F5_5","F6_5", "F7_5", "F8_5", "F9_5") partialCorr <- function (cond, mat) cor(qr.resid(qr(cbind(1, mat[, cond])), mat[, -cond])) # matrix keep label d=partialCorr(c(3,2),x) d # array looses label bsp1 <- array(0, c(7,7,36)) k <- 0 for(i in 1:8) for(j in (i+1):9) { k <- k+1 bsp1[, , k] <- partialCorr(c(i, j), x) } bsp1 # I tried something to label inside the loop bsp1 <- array(0, c(7,7,36)) k <- 0 for(i in 1:8) for(j in (i+1):9) { k <- k+1 bsp1[, , k] <- partialCorr(c(i, j), x) dimnames(bsp1[,,k])=dimnames(partialCorr(c(i,j), x)) } bsp1 # I tried something to label outside the loop but can't directy adress the array labels <- array(0, c(7,1,36)) k <- 0 for(i in 1:8) for(j in (i+1):9) { k <- k+1 labels[, , k] <- as.vector(rownames(partialCorr(c(i,j), x))) } labels for (k in 1:36){ dimnames(bsp1[,,k])=list(c(labels[,1,k]),c(labels[,1,k])) } bsp1 -- View this message in context: http://www.nabble.com/-R--Problem-labelling-arrays-tf2910585.html#a8132366 Sent from the R help mailing list archive at Nabble.com.
