描述----------Description----------
Display the object, by printing, plotting or whatever suits its class. This function exists to be specialized by methods. The default method calls showDefault.
显示对象，以印刷，打印或任何适合其类。此功能存在方法专业。默认的方法调用showDefault。
Formal methods for show will usually be invoked for automatic printing (see the details).
show正式方法通常会被自动打印（见详情）调用。
用法----------Usage----------
show(object)
参数----------Arguments----------
参数：object
Any R object
任何R对象
Details
详情----------Details----------
Objects from an S4 class (a class defined by a call to setClass) will be displayed automatically is if by a call to show. S4 objects that occur as attributes of S3 objects will also be displayed in this form; conversely, S3 objects encountered as slots in S4 objects will be printed using the S3 convention, as if by a call to print.
从S4级（调用setClass由定义一个类）的对象将自动显示的是调用show由。 S3对象的属性发生S4对象也将被显示在此表格;相反，在S4对象插槽遇到S3对象将使用S3公约“，如果由调用print印。
Methods defined for show will only be inherited by simple inheritance, since otherwise the method would not receive the complete, original object, with misleading results. See the simpleInheritanceOnly argument to setGeneric and the discussion in setIs for the general concept.
show定义的方法，只会简单的继承被继承，否则该方法将不会收到完整的，原来的对象，有误导性的结果。看到simpleInheritanceOnly参数setGeneric和setIs一般概念的讨论。
值----------Value----------
show returns an invisible NULL.
show返回一个无形的NULL。

showMethods prints all the methods for one or more functions.
showMethods打印一个或多个功能的所有方法。
举例----------Examples----------
## following the example shown in the setMethod documentation ...[＃setMethod文档中所示的例子...]
setClass("track",
representation(x="numeric", y="numeric"))
setClass("trackCurve",
representation("track", smooth = "numeric"))
t1 <- new("track", x=1:20, y=(1:20)^2)
tc1 <- new("trackCurve", t1)
setMethod("show", "track",
function(object)print(rbind(x = object@x, y=object@y))
)
## The method will now be used for automatic printing of t1[＃现在可以使用该方法将自动打印T1]
t1
