Betreff: Re: [R] Test for column equality across matrices
I tried it on a slightly bigger dataset:
A1 <- matrix(t(expand.grid(1:90, 15, 16)), nrow = 3)
B1 <- combn(90, 3)
which(is.
[[14]]
#[1] 14 15 16
is.element(B1Sp[[44331]],A1Sp[[14]])
#[1] TRUE TRUE TRUE

Try
[1] 3 555
dim(B)
#[1] 3 560
#or
B2<-B[,is.na(match(interaction(as.data.frame(t(B))),interaction(as.data.frame(t(A)]
identical(B1,B2)
#[1] TRUE

Dear list,
I have two matrices
A <- matrix(t(expand.grid(c(1,2,3,4,5), 15, 16)), nrow = 3)
B <- combn(16, 3)
Now I would like to exclude all columns from the 560 columns in B which are
identical to any 1 of the 6 columns in A. How could I do this?
Many thanks and best wishes,
Alrik
