Question

R software

Create a list made up of two Vectors, two Data frames and Two Matrices.

i) Name the elements of the list appropriately

ii) Output just the two vectors

iii) Output just the two matrices

Answer 1

#Code of the required program

v1=c(1,2,3,4,5) #creating the first vector
v2=c(6,7,8,9,10) #creating the second vector

name1=c("A","B","C","D")
age1=c(10,12,15,20)
name2=c("E","F","G","H")
age2=c(16,19,21,22)
d1=cbind(name1,age1)
d2=cbind(name2,age2)
dd1=data.frame(d1) #creating the first data frame
dd2=data.frame(d2) #creating the second data frame

m1=matrix(c(1,2,3,4,5,6,7,8,9),nrow=3,byrow=T) #creating the first matrix of order 3*3
m2=matrix(c(9,8,7,6,5,4,3,2,1,0,7,4),nrow=4,byrow=T)#creating the second matrix of order 4*3

L1=list(v1,v2) #creating first list containing 2 vectors
L2=list(dd1,dd2) #creating second list containing 2 dataframes
L3=list(m1,m2) #creating third list containing 2 matrices

L=list(L1,L2,L3) # creating list of lists

L[[1]] #printing the 2 vectors, which are the 1st element of the main list
L[[3]] #printing the 2 matrices, which are the 3rd element of the main list
