R DataFrame

R DataFrame

An R DataFrame is kind of a tabular data. It contains a list of columns where each column has same number of rows.

In this tutorial, we will see a basic example of an R DataFrame, and the list of tutorials covering different scenarios of Data Frame.

Example for R DataFrame

The following is an example for R Data Frame with three columns and four rows.

c1, c2, c3 are the columns. 1, 2, 3 and 4 are the rows.

And we have used following R script to generate the above Data Frame.

df <- data.frame("c1" = c(41, 42, 43, 44),
                 "c2" = c(45, 46, 47, 48),
                 "c3" = c(49, 50, 51, 52))

data.frame() function creates a new DataFrame.
