Hi everyone:
I have a kinda easy question but i do not know how to solve that in a simple
way.
I want to compare the rows of two matrices.
col1 <- c(1,2,3,4,5,6)
col2 <- c(6,5,4,3,2,1)
m <- cbind(col1, col2)
col3 <- c(1,3,2,6)
col4 <- c(6,3,5,1)
n <- cbind(col3, col4)
In matrix n, for example the first row is (1,6), it is also some row in
matrix m, i want the code results "TRUE". then for the 2nd row (3,3), it
should be FALSE.
So in this case it should be (TRUE, FALSE, TRUE, TRUE)
I tried %in% or is.element for a row in n and matrix m, but it does not work.
I think I can also write two loops to compare the rows of m and n one by one,
but it takes a long time to run.
Could anyone tell me how to solve this?
Thank you very much!!
