Makes an event scale from a specification found in a file or using the types and variables parameters. If a file is specified it is assumed to be headerless and to contain event codes in the first column and numerical values in the second column.

Scales must be assigned a name and may also be assigned a description. If you wish to assign codes without a specified value to some particular value, set default to something other than NA.
