Assignment 1

My first assignment has 3 parts.

(a)

It helps to autocomplete data and that’s not like a static analysis.Most important thing to prioritize in development.R’s tools are mature,sophisticated libraries for building kind of the foundational piece of what you would need for framework like shiny.

(b)

1-Data structures: In R programming c( ) function is used to create a vector.In Python, use the “[]” to create a vector.

x <- c(2, 3, 4, 6, 3)
x

[1] 2 3 4 6 3

vec_row = [1, 2, 3]
vec_row

[1, 2, 3]

2-Loops:

for (i in 1:4) {
  print(i)
}

[1] 1
[1] 2
[1] 3
[1] 4

for i in range(1, 4):
  print(i)

1
2
3

3-Data Types: In R; <- used when assigning. In python; = used when assigning.

y <- "nurgov"
y

[1] "nurgov"

y = "nurgov"
y

[1] "nurgov"

(c)

data <- na_example
