If,else and elseif is used to apply logic to our code based on certain conditions.
The basic syntax of if,else statement is
if (condition) {
# Code to execute if true
} else {
# Code to execute if above was not true
}
Let us explain with an example
# Items sold that day
ham <- 10
cheese <- 10
# Report to HQ
report <- 'blank'
if(ham >= 10 & cheese >= 10){
report <- "Strong sales of both items"
}else if(ham == 0 & cheese == 0){
report <- "Nothing sold!"
}else{
report <- 'We had some sales'
}
print(report)
Output:
[1] "Strong sales of both items"
