WEEK 3:
A) Implement R Script to create a list.
list1 <- list(1, "pradeep", c(1,2,3), 6:10)
list1
Output:
[[1]]
[1] 1
[[2]]
[1] "pradeep"
[[3]]
[1] 1 2 3
[[4]]
[1] 6 7 8 9 10
second method:
list1 <- list(1, "pradeep", c(1,2,3), 6:10)
str(list1)
Output:
List of 4
$ : num 1
$ : chr "pradeep"
$ : num [1:3] 1 2 3
$ : int [6:10] 6 7 8 9 10
B) Implement R Script to access elements in the list.
x <- list(TRUE, 14, "pradeep")
print(x[1])
print(x[2])
print(x[3])
Output:
[[1]]
[1] TRUE
[[1]]
[1] 14
[[1]]
[1] "pradeep"
C) Implement R Script to merge two or more lists. Implement R Script to perform matrix
operation.
matrix(
c(1,2,3,4,5,6,7,8),
nrow = 4,
ncol = 2,
byrow = FALSE )
Output:
[,1] [,2]
[1,] 1 5
[2,] 2 6
[3,] 3 7
[4,] 4 8
