How to concatenate two or more vectors in R?

R ProgrammingServer Side ProgrammingProgramming

The concatenation of vectors can be done by using combination function c. For example, if we have three vectors x, y, z then the concatenation of these vectors can be done as c(x,y,z). Also, we can concatenate different types of vectors at the same time using the same same function.
