How to convert a vector into data frame in R?

R ProgrammingServer Side ProgrammingProgramming

If we want to convert an object into a data frame then as.data.frame function can be used, we just need to read the object that we want to convert with as.data.frame. For example, if we have a vector x then it can be converted to data frame by using as.data.frame(x) and this can be done for a matrix as well.
