join!

join!(X, Y)

X is a vector/matrix/table.

Y is a scalar/vector/matrix/table.

If X is a vector, Y is a scalar/vector; if X is a matrix, Y is a vector/matrix; if X is a table, Y is a vector/table.

Merge X and Y, and assign the result to X. The resulting object has the same data type as X.

If X is a vector, Y must be a scalar/vector. The result is a vector.

x=[1,2,3]
x.join!(4)
x;
// output
[1,2,3,4]

x.join!(5 6 7)
x;
// output
[1,2,3,4,5,6,7]

If X is a matrix, Y must be a vector/matrix with the same number of rows as X. The result is a matrix with the same number of rows as X.

x=1..6$2:3
join!(x, [7,8])
x;

x.join!(9..12$2:2)
x;

If X is a table, Y must be a table or a vector with the same number of rows as X. The result is a table with the same number of rows as X.

a=table(1..3 as x, 4.5 6.7 8.5 as y);
a;

b=table(700 500 800 as z);
b;

join!(a,b);
a;

a=table(1..3 as x, `IBM`C`AAPL as y);
b=table(172.3 25 106.5 as z);
a.join!(b);
a;
