typecode(x) produces a one-letter string identifying the type of its argument. In most cases, the code is the first (lowercase) letter of the type, as "i" for the integer type. Structure types are in uppercase, as "L" for the list type. All records have the code "R". The code "C" is used for the co-expression type to avoid conflict for the "c" for the cset type. In the case of graphics, "w" is produced for windows.
