dim命令r语言dim在r语言中 2.5 多维数组和矩阵2.5.1 生成数组或矩阵数组有一个特征属性叫做维数向量(dim属性),维数向量是一个元素取正整数的向量,其长度是数组的维数,比如维数向量有两个元素时数组为2维数组(矩阵)。维数向量的每一个元素指定了该下标的上界,下标的下界总为11.将向量定义成数组向量只有定义了维数...

Get or Set Dimensions of a Matrix in R Programming - dim() Function R语言中的 dim()函数用于获取或设置维度指定的矩阵、数组或dataframe。 语法:dim(x) 参数:x:数组、矩阵或dataframe。 示例1: # R program to illustrate # dim function # Getting R Biochemical Oxygen Demand Dataset BOD # Getting ...
You can enable the DIM function in either of the following ways: Periodically enabling the DIM function: In this mode, the device enables the DIM function at a specified time every day to measure the running process memory. Immediately enabling the DIM function: In this mode, the DIM function...
