Write your first R code

Running code in R is easy (if copy/paste). Our motive here is not to teach you R. However, you’ll catch with basic R code in no-time.

• First, make sure you’ve installed R .
• Then, search and open R.
• Copy the code below and run it in your R console

Run the code below:

# printing 
print("Hello World")

[1] "Hello World"

#assignment 
 a <- 10 
 b <- 15

#add 
 a + b

[1] 25

#add + assign 
  c <- a + b

# print 1 to 100 
  1:10

 [1]  1  2  3  4  5  6  7  8  9 10

# sum from 1 to 100 
sum(1:100)

[1] 5050

# mean / average 
mean(c(10, 15, 20, 25))

[1] 17.5

# median / central value 
median(c(5, 10, 15, 25, 30))

[1] 15

# square root 
sqrt(64)

[1] 8

# function 
addition <- function(x, y){ x + y }

# calling function 
addition(10, 15)

[1] 25
