as()函数比as.data.frame()、as.array()等函数广泛,更具有强制性。 一、 as()函数:强制给对象到定类。如关联规则(arules)类型、智能推荐("binaryRatingMatrix""recommenderlab")类型,as.data.frame()、as.array()等函数就做不到转换。使用:as ( object , class ,strict= true , ext )as ( object , ...
1、数据框是R语言里中的一种数据结构,其内部可以由多种数据类型,每一列是一个变量,每行是一个观测记录。在R中数据框是很通用的数据结构,它是一种特殊的列表对象 2、初始化数据框 > mydataframe=data.frame( + name=c(\"张三\", \"李四\", \"王五\", \"赵六\", \"丁一\"), + sex=c(\"F\...

addEventListener的第三个参数如果为false(默认为flase), 回调事件会在冒泡状态的时候执行 ;否则会在目标状态执行。当参数为true时 ,在A上注册,不存在冒泡状态 , 回掉函数不会执行。 事件机制的3个阶段 Event有一个属性:eventPhase,可以为以下3个值:
Movie frame, returned as a structure with two fields: cdata— The image data stored as an array ofuint8values. The size of the image data array depends on your screen resolution. colormap— The colormap. On true color systems, this field is empty. ...
