Individual elements of an array may be referenced by giving the name of the array followed by the subscripts in square brackets, separated by commas. The values in the data vector give the values in the array in the same order as they would occur in FORTRAN, that is “column major order,” with the first subscript moving fastest and the last subscript slowest.įor example if the dimension vector for an array, say a, is c(3,4,2) then there are 3 * 4 * 2 = 24 entries in a and the data vector holds them in the order a, a, …, a, a.Īrrays can be one-dimensional: such arrays are usually treated in the same way as vectors (including when printing), but the exceptions can cause confusion.ĥ.2 Array indexing. Other functions such as matrix() and array() are available for simpler and more natural looking assignments, as we shall see in The array() function. ![]() Gives it the dim attribute that allows it to be treated as a 3 by 5 by 100 array.
