How to compare the values of two vectors in R?
Today, we’ll talk about comparing two R vectors to see what components (values).
Here, we have two choices:
The indexes of common elements are returned by the match () function in R.
- Indicating if a value from the first vector was present in the second.
- The percent in percent operation produces a vector of True or False answers.
Finding Values in Vectors using R Match
Starting with the R match() function, let’s go on.
The first position of the matching value is returned by the r match example.
match(12, Value)  3
Example of an r match with multiple values
match (c(13,12), Value)  2 3
The initial position of each of the two values is returned by the R match function when we pass it a vector of multiple values.
Operator – Boolean Equivalent for percent in percent
Do you only require a True/False response?
Use the percent in percent operator, if possible. Similar operations are carried out, and the result is returned as a Boolean indicator indicating if the value is present.
For an example of the R percent in percent operator
by utilizing the percent in percent operator, check for a single value.
14 %in% Value  TRUE
Utilize the percent in percent operator to verify a vector of multiple values.
c(10, 12) %in% Value  FALSE TRUE
what values the percent in percent operator treats when it can’t
c(10, 12, 14) %in% Value  FALSE TRUE TRUE
