矩阵(matrix)是一个二维数组,矩阵内所有元素必须具有相同的模式(数值型、字符型、逻辑型),矩阵可以使用向量、数据框等数据赋值转换,方法如下所示: matrix(vector, nrow=m, ncol=n) #使用向量生成m行n列的矩阵 matrix(NA, nrow=m, ncol=n) #生成一个m行n列的空矩阵 as.matrix(x) #将对象转换为矩阵 is....

matrixpls uses test driven development with Runit. This means that the tests are written first and then software is implemented to conform with the tests. Requirements and Installation To install the latest development version of matrixpls from github (using the package "devtools"), run in your ...
The ssgraph package offers Bayesian inference in undirected graphical models using spike-and-slab priors for multivariate continuous, discrete, and mixed data. Computationally intensive tasks of the package are using OpenMP via C++.The GPUmatrix package can offload calculations to the GPU while providin...
Matrix:著名的稀疏矩阵包 6、统计建模与推断 下述R包是统计建模最常用的几个R包,其中的一些R包适用于多个主题。 car:提供了大量的增强版的拟合和评价回归模型的函数。 Hmisc:提供各种用于数据分析的函数 multcomp:参数模型中的常见线性假设的同时检验和置信区间计算,包括线性、广义线性、线性混合效应和生存模型。
Matrix包中的函数可以用于创建、操作和计算矩阵和稀疏矩阵,包括矩阵的转置、乘法、加法、求逆等操作。Matrix包还提供了一些特殊的矩阵类型,如对称矩阵、三角矩阵和对角矩阵等,这些矩阵类型在某些情况下可以提高计算效率。Matrix包还支持多线程计算,可以利用多核CPU提高计算速度。参考: Matrix package - RDocumentation...
matrixkit is an R package that provides a first aid kit for some matrix operations commonly used in multivariate data analysis methods. Motivation I developed matrixkit as part of a major project to develop a set of tools for multiblock methods. The main idea behind matrixkit is to have a ...
