To check if a string contains only numeric digits in R, you can use regular expressions or functions like 'grepl' to match numeric patterns in the string.
In this example,
containsOnlyNumericDigits <- function(str) {
grepl('^[0-9]+$', str)
}
str <- '12345'
allDigits <- containsOnlyNumericDigits(str)
print(paste('String contains only numeric digits:', allDigits))
String contains only numeric digits: TRUE
In this tutorial, we learned How to Check if String contains only Numeric Digits in R language with well detailed examples.
