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]))
}
