array to data.frame
Dear Peter:
Does the following not work in certain situations:
A <- array(1:4, dim=c(2,2))
dimnames(A) <- list(NULL, c("a", "b"))
as.data.frame(A)
Or is it deprecated for other reasons?
Thanks,
Spencer Graves

Hi,
How i can convert a array in to data.frame structure?
For example,
vinteesete<-array(c(1,0,6,4,22,29,11,7,6,2,8,7,21,25,5,6,1,0,11,6,14,24,13,10,2,2,15,13,14,17,9,8,1,2,16,9,14,23,9,6,6,2,17,13,10,20,7,5),
dim=c(2,4,6), dimnames=list(grupo=c("I","II"),
opiniao=c("Ma","Regular","Boa","MBoa",),
relacao=c("atencao","sensibilidade","compreensao","tertempo","ouvir","envolvencia")))
as.data.frame(as.table(vinteesete)) (or as.data.frame.table(vinteesete), but with S4 methods coming in it is increasingly considered bad style to apply methods to objects that are not of the requisite class.)
