R中一切都是vector,vecotor的每个component必须类型一致(character,numeric,integer...)! vector 是没有dimensions的也没有attributes,所以去掉dimension和attributes就成了vector(其实dimension可以作为attributes的一个属性存在但是named** 命名**一般不会作为attributes的属性的) 解释下 0.1为何没有dimensions? ---这里其实...
On yourway from rags(贫穷) to riches(富有), you will make extensive(广泛) use of vectors(向量).Vectors are one-dimension arrays that can hold numeric data, character data, orlogical data. In other words, a vector is a simple tool to store data. Forexample, you can store your daily g...
自定义行名/列名,可用于解决原始矩阵行名/列名不能有重复的问题,或使用特殊符号等: # use a named vector to make sure the correspondance between row names and row labels is correct row_labels = structure(paste0(letters[1:24], 1:24), names = paste0("row", 1:24)) column_labels = structur...

is.vector()测试某个对象是否为原子型向量。 每个原子型向量都将其值存储在一个一维向量中,并且只能是一种类型的数据。R可以识别六种基本类型:double、integer、character、logical、complex、raw(双整型、整型、字符型、逻辑型、复数类型、原始类型) #R规范:输入整数后键入L表示输入一个整型数值。输入一个字符,相应...
