Explain with an example how to implement if,else and elseif statement in R.
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"
