N Function

Contents Index

The N function returns the number of argument variables which have nonmissing values. Examples:

count=N(x, y, z);
count=N(of x1-x10);
count=N(of x y z);

The first and last example assign count the number of the variables x, y, and z which have nonmissing values. Note the differences in syntax. The last example returns the number of the variables among x1, ..., x10 which have nonmissing values.
