Question 1 Basic R operations (a) Let x

Solution

Answer of question 1.

part (a)

x=1 2 3 4 5 6 7 8 9 10 11 12

[1] 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 6 6 6 6 6 6 7 7 7 7
[26] 7 7 7 8 8 8 8 8 8 8 8 9 9 9 9 9 9 9 9 9 10 10 10 10 10
[51] 10 10 10 10 10 11 11 11 11 11 11 11 11 11 11 11 12 12 12 12 12 12 12 12 12
[76] 12 12 12

part(b)

this command matrix (x, ncol=3,byrow=T) will generate a matrix of number of column =3 and element of matrix will be arranged row wise.i.e first row will be filled as 1, 2 ,3 and next row as 4,5,6 and so on as   [,1] [,2] [,3]
[1,] 1 2 3
[2,] 4 5 6
[3,] 7 8 9
[4,] 10 11 12

dim(x) will genrate number of number of row and number of column of matrix x.

c(4,3) also generate 4,3 as an element , where as dim(x) is also generating 4.3 but it is number of row and number of column in matrix

Part (c)

sample (x) takes a sample from the elements of x using either with or without replacement.

order returns a permutation which rearranges its first argument into ascending or descending order, breaking ties by further arguments.
