A categorical variable v1 in a data frame d1 may have values represented by using the letters from a to z. i want to create a subset d2, which excludes a few values, say, b, n and t. essentially, i need a c. Operators. r's binary and logical operators will look very acquainted to programmers. observe that binary operators work on vectors and matrices as well as scalars. Matrices are the r objects in which the elements are arranged in a -dimensional rectangular layout. they contain factors of the identical atomic types. though we will create a matrix containing simplest characters or most effective logical values, they're not of tons use.
