Exception in Logical Comparison with string data (Continuing): Logical comparisons of string data in R are performed based on alphabetical ordering, ignoring letter case at first. However, when two strings are identical apart from case, R uses case to break the tie—uppercase letters are considered greater than their lowercase counterparts (i.e., "A" > "a"). R compares the strings character by character from the beginning until it can determine which one is greater. For example: "uBc" and "ubc" are identical if case is ignored. R therefore compares them character by character: The first characters, "u" and "u", are both lowercase—no difference. The second characters, "B" and "b", differ in case. Since "B" is uppercase, it is considered greater than lowercase "b". Thus, R stops comparing further characters and concludes that "uBc" > "ubc". Which of the following comparisons result in TRUE?

Options
A."Apple">"apple"
B."aPple"<"Apple"
C."applE">"apple"
D."APple">"ApPLE"

Step-by-Step Analysis
To determine which of the given string comparisons are TRUE under R's rules, we must follow the described comparison process: compare character by character, using case-insensitive comparison first, and only when strings are identical except for case do we apply the case-based tie-breaker where uppercase is considered greater than lowercase. Option 1: "Apple">"apple" - Compare ignoring case: both strings are the same sequence of letters, so the comparison is a tie up to the entire string. - App......Login to view full explanation
