public class SVarFixFact
Statistical Variable
IMPORTANT NOTES:
NOTE: do NOT remove any elements from SVar !! Any Vector methods that modify contents except for "add" are NOT safe (for categorized vars) as they DON'T update categories!! The "is number" property is set accoding to the first added (non-null) element - thus you should NOT mix numeric and non-numeric objects. It is safe to insert numbers in non-numeric value, but NOT vice-versa as for numeric variables the detection of min/max casts any object to Number.

SVarFixFact(java.lang.String Name,
int[] ids,
java.lang.String[] cnames)
construct new variable and add first element |
Method Summary | |
---|---|
boolean |
add(java.lang.Object o)
adds a new case to the variable. the exact behavior is implementation-dependent. |
java.lang.Object |
at(int i)
|
int |
atI(int i)
|
void |
categorize(boolean rebuild)
define the variable explicitely as categorical |
void |
createMissingsCat()
|
void |
dropCat()
define the variable explicitely as non-categorial (drop category list) |
java.lang.Object |
getCatAt(int i)
returns the category with index ID or null if variable is not categorial |
java.lang.Object[] |
getCategories()
returns new, fixed array of categories |
int |
getCatIndex(int i)
returns ID of the category of i-th case in the variable or -1 if i oob |
int |
getCatIndex(java.lang.Object o)
returns the ID of the category |
int |
getNumCats()
returns the number of categories for this variable or 0 if the variable is not categorial |
int[] |
getRanked(SMarker m,
int markspec)
returns list of indexes ordered by rank, for non-cat, num vars only. missing values are omitted. |
int |
getSizeCat(java.lang.Object o)
returns size of the category o. |
int |
getSizeCatAt(int i)
returns size of the category with index ID or -1 if variable is not categorial or index oob |
boolean |
insert(java.lang.Object o,
int index)
inserts a new case to the variable at specified index. the exact behavior is implementation-dependent. |
boolean |
isLastMissing()
return true if missings have their own category (the last one) |
boolean |
remove(int index)
removes a case from the variable at specified index. the exact behavior is implementation-dependent. |
boolean |
replace(int i,
java.lang.Object o)
replaces an element at specified position |
void |
setAllEmpty(int size)
we want to be able to make an empty SVar with the specified size and null content (added 28.12.03 MH). |
void |
setCategorical(boolean nc)
define the type of the variable. note that setting nc to false does not necessarily drop categories information. this method should be used for quick toggling of the variable type |
int |
size()
returns the size (number of cases) of the variable |
void |
sortCategories(int method)
sort categories by specifeid method |
java.lang.String |
toString()

- first element to be added - see add(java.lang.Object)
for details. If null
is passed then no element is added. The usage of this constructor is discouraged/deprecated because first entry cannot contain a missing value thus leading to a loss of generality.Method Detail |
