intrsectsa#

Purpose#

Returns the intersection of two string vectors, with duplicates removed.

Note

This function is deprecated, use intrsect() instead.

Format#

s_intr = intrsectsa(sv1, sv2)#

Parameters:

sv1 (Nx1 or 1xN string vector) – data
sv2 (Mx1 or 1xM string vector) – data

Returns:

s_intr (Lx1 vector) – all unique strings that are in both sv1 and sv2 sorted in ascending order.

Examples#

// Define string vector number one
vars_a = "age" $| "weight" $| "bmi";

// Define string vector number two
vars_b = "hdl" $| "ldl" $| "age" $| "bmi" $| "smoking";

shared_vars = intrsectsa(vars_a, vars_b);
print "Both studies reported the following variables:";
print shared_vars;

The code above returns:

Both studies reported the following variables:
             age              bmi

Remarks#

Place smaller vector first for fastest operation.
If there are a lot of duplicates it is faster to remove them with unique() before calling intrsectsa().
