[R] Function in nested loop

Hi all, I would like to run a function with several nested conditions, which are completely factorial. The input data (x1) has two different sample sizes, so: x1 <- dat1 x1 <- dat2 Then a can have 3 different values: a <- 0.15 a <- 0.35 a <- 0.50 Then b can have 2 different values: b <- data.matr
