And as.logical() does not seem to be able to convert characters (i.e. as.logical("a > 2")) does not work. My question: Is there some function I can put x through that allows R to view it not as a character, but rather as a logical statement?

In R, true values are designated with TRUE, and false values with FALSE. When you index a vector with a logical vector, R will return values of the vector for which the indexing vector is TRUE. Details. TRUE and FALSE are reserved words denoting logical constants in the R language, whereas T and F are global variables whose initial values set to these.

In boolean logic, logical nor or joint denial is a truth-functional operator which produces a result that is the negation of logical or.That is, a sentence of the form (p NOR q) is true precisely when neither p nor q is true—i.e. when both of p and q are false.In grammar, nor is a coordinating conjunction.. The NOR operator is also known as Peirce's arrow—Charles Sanders Peirce introduced

Logical Operators R has an intuitive method for recoding variables, which relies on logical operators that return statements of TRUE and FALSE.A mathematical operator (such as ==, !=, >, >= <, and <=) takes two objects of equal dimensions (scalars, vectors of the same length, matrices with the same number of rows and columns, or similarly dimensioned arrays) and compares every element in the In boolean logic, logical nor or joint denial is a truth-functional operator which produces a result that is the negation of logical or.That is, a sentence of the form (p NOR q) is true precisely when neither p nor q is true—i.e. when both of p and q are false.
logical creates a logical vector of the specified length. Each element of the vector is equal to FALSE. as.logical attempts to coerce its argument to be of logical type.
