Dear Jean,
Thank you, expand.grid was the function I needed.

Perhaps repeated use of the outer() function. You could also write a
multi.outer() or adopt one of the solutions here:

See
?expand.grid
For example,
df <- expand.grid(L=L, AR=AR, SO=SO, T=T)
df$y <- fun(df$L, df$AR, df$SO, df$T)

Hello,
probably it is quite easy but I can get it: I have
mulitple numeric vectors and a function using
all of them to calculate a new value:
L <- c(200,400,600)
AR <- c(1.5)
SO <- c(1,3,5)
T <- c(30,365)
fun <- function(L,AR,SO,T){
exp(L*AR+sqrt(SO)*log(T))
}
How can I get an array or
4 matches
