Saving rows into variables in R

Question

I have a 18-by-48 matrix. Is there a way to save each of the 18 rows automatically in a separate variable (e.g., from r1 to r18) ?

Answer 1

I'd definitely advise against splitting a data.frame or matrix into its constituent rows. If i absolutely had to split the rows up, I'd put them in a list then operate from there.

If you desperately had to split it up, you could do something like this:

toy <- matrix(1:(18*48),18,48)

variables <- list()
for(i in 1:nrow(toy)){
  variables[[paste0("variable", i)]] <- toy[i,]
}

list2env(variables, envir = .GlobalEnv)

I'd be inclined to stop after the for loop and avoid the list2env. But I think this should give you your result.
