Vector vs. Data frame in R

What is the difference between a vector and a data frame in R? Under what circumstances vectors should be converted to data frames?

Another good point to note is that when running code, operations on matrixes are (most of the time) much faster then on data frames.

A vector has 1 dimension while a data frame has 2. I can't think of a good reason to convert a single vector into a data frame. That question generally arises when you have multiple vectors.

A better question is what is the difference between a data frame and a matrix: a data frame can have different data types for each column, while a matrix is all one data type. Behind the scenes, a data frame is really a list with equal length vectors at each index.
