backbone {XNAString} | R Documentation |
Getter methods enable extraction of single slots from XNAString and XNAStringSet objects. E.g. name method extracts name slot from XNAString/XNAStringSet object.
backbone(x, ...) ## S4 method for signature 'XNAString' backbone(x) ## S4 method for signature 'XNAStringSet' backbone(x, i = 1) backbone(x, ...) <- value ## S4 replacement method for signature 'XNAString' backbone(x) <- value ## S4 replacement method for signature 'XNAStringSet' backbone(x, i = 1) <- value
x |
XNAString/XNAStringSet object |
... |
optional arguments to generic function to support additional methods |
i |
numeric - possibilities: 1 or 2. If 1 - 1st slots elements printed out, 2nd otherwise. In case the second element is not in the object, empty char created. This parameter is only available for XNAStringSet objects. |
value |
character vector applied only for setter method |
Setter methods enable overwriting single slots from XNAString and XNAStringSet objects. E.g. name<- method overwrites existing name slot
vector in getter method, XNAStringSet object (with replaced name slot) in setter method
