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