matrices must have every element be the same class Data frames also have a special attribute called row.names Data frames are usually created by calling read.table() or read.csv() Can be converted to a matrix by calling data.matrix() > x <- data.frame(foo = 1:4, bar = c(T, T,...
In programming, data type is an important concept. Variables can store data of different types, and different types can do different things. In R, variables do not need to be declared with any particular type, and can even change type after they have been set: ...
R语言中的数据类型(Data Types)R语言的对象(Objects)主要包括向量、矩阵、数组、数据框和列表。R语言的对象有五种最基本的类型,即,字符型(character)、数值型(numeric,包括小数)、整型(integer)、复数型(complex)以及逻辑型(logical,TRUE/FALSE)属性是R语言对象的一部分。主要包括以下几种:名字(names,dimnames),...
