Goal: from a list of vectors of equal length, create a matrix where each vector becomes a row. Example: >a<-list()>for(iin1:10)a[[i]]<-c(i,1:5)>a[[1]][1]112345[[2]][1]212345[[3]][1]312345[[4]][1]412345[[5]][1]512345[[6]][1]612345[[7]][1]712345[[8]][1...
in R allows you to gather（收集） a variety of（各种各样的） objects under one name (thatis, the name of the list) in an ordered way. These objects can be matrices,vectors, data frames, even other lists, etc. It is not even required that theseobjects are related to each other in ...
List with vectors of onesGaston Sanchez
A list in R allows you to gather(收集) a variety of(各种各样的) objects under one name (thatis, the name of the list) in an ordered way. These objects can be matrices,vectors, data frames, even other lists, etc. It is not even required that theseobjects are related to each other...
列表是R语言中的对象,它包含不同类型的元素,比如 - 数字,字符串,向量和另一个列表等。一个列表还可以包含一个矩阵或一个函数作为它的元素。使用list()函数创建列表。 创建一个列表 下面是一个例子来创建一个包含字符串,数字,向量和逻辑值的列表 # Create a list containing strings, numbers, vectors and a ...

A Data Frame is the most common way of storing and working with data in R. Data Frames are nothing more than a list of equal-length vectors, making them a 2-dimensional structure. Data Frames share the properties of both the matrix and list. ...
