Creating a Data Frame with Functions in R In this article, we will explore the process of creating a data frame in R and applying functions to specific columns. We will cover the basics of data frames, how to create them, and how to apply functions using conditional statements. Understanding Data Frames A data frame is a fundamental structure in R that stores data in a tabular format with rows and columns.

Introduction In this article, we’ll delve into the process of merging two dataframes based on a timestamp column. We’ll use R and the data.table package to achieve this. The problem statement involves two dataframes, DF1 and DF2, with different structures. DF1 contains timestamp information in the form of Date and TrackTime, while DF2 contains a single timestamp column called DATE_SIGHT. We need to find the overlapping rows between these two dataframes based on the timestamp information.
