An object of class dimVar holds all necessary information about a single
dimensional variable such as original and standardized codes, the level-structure,
the hierarchical structure, codes that may be (temporarily) removed from
building the complete hierarchy (dups) and their corresponding codes that correspond
to these duplicated codes.
codesOriginal:a character vector (or NULL) holding original variable codes
codesDefault:a character vector (or NULL) holding standardized codes
codesMinimal:a logical vector (or NULL) defining if a code is required to build the complete hierarchy or not (then the code is a (sub)total)
vName:character vector of length 1 (or NULL) defining the variable name of the dimensional variable
levels:a numeric vector (or NULL) defining the level structure. For each code the corresponding level is listed with the grand-total always having level==1
structure:a numeric vector (or NULL) with length of the total number of levels. Each element shows how many digits the i-th level allocates within the standardized codes (note: level 1 always allocates exactly 1 digit in the standardized codes)
dims:a list (or NULL) defining the hierarchical structure of the dimensional variable. Each list-element is a character vector with elements available in slot codesDefault and the first element always being a (sub)total and the remaining elements being the codes that contribute to the (sub)total
dups:character vector (or NULL) having showing original codes that are duplicates in the hierarchy and can temporarily removed when building a table with this dimensional variable
dupsUp:character vector (or NULL) with original codes that are the corresponding upper-levels to the codes that may be removed because they are duplicates and that are listed in slot dups
objects of class dimVar form the base for elements in slot dimInfo of class dimInfo.
