Data Frames and Vectors
Data Frames and Vectors
Vectors are sequences of data of the same datatype, and they are the fundamental unit we use for analysis in R and other statistical programs. When vectors are combined, we get data frames where the columns are the different variable we are looking at and the rows present unique values/observations. Understanding and manipulating vectors and data frames is a key skill for quantitative analysis.
