Como o post em As funções do “olá mundo” foram bastante apreciadas pela comunidade R, segue-se a segunda rodada de funções para o aspirante a programador R.
# If else statement:
# See the code syntax below for if else statement
x=10
if(x>1){
print(“x is greater than 1”)
}else{
print(“x is less than 1”)
}
# See the code below for nested if else statement
x=10
if(x>1 & x8 & x 4) {
break
}
}
# Break statement:
# A break statement is used in a loop to stop the iterations and flow the control outside of the loop.
#Below code shows break statement:
x = 1:10
for (i in x){
if (i == 6){
break
}
print(i)
}
# Next statement:
# Next statement enables to skip the current iteration of a loop without terminating it.
#Below code shows next statement
x = 1: 4
for (i in x) {
if (i == 2){
next
}
print(i)
}
# function
words = c(“R”, “datascience”, “machinelearning”,”algorithms”,”AI”)
words.names = function(x) {
for(name in x){
print(name)
}
}
words.names(words) # Calling the function
# extract the elements above the main diagonal of a (square) matrix
# example of a correlation matrix
cor_matrix As programming is the best way to learn and think, have fun programming awesome functions!
