Merge command in Stata serves the purpose of merging data or combining different datasets. Within the Merge command, there are several merge types, including one to one merge, many to one merge, one to many merge, and many to many merge, each with its unique applications. In their respective sections, we will explore these merge […]
Data appending in Stata involves stacking one dataset on top of another to create a single dataset. We will cover different scenarios and options for this process. Download Code and Data Direct Data Appending: When you have separate data files and want to combine them, you can use the “append” command. This straightforward approach involves
In a data frame in R, one can create or modify variables either using base R method or by using the mutate function from the tidyverse package. Lets first discuss the base R method. Load the following data in R for further understanding of how to create a variable in a date frame, Download Example
Using mutate function to create a variable in Data frame Read More »
In R, you can change the data type of variables in data frame for data and statistical analysis. Before going further about changing data type in R, it’s important to know the difference between a vector and data frame. While the vector is a data set with same type of data, data frame contains data
In R, while doing data manipulation and analysis, one might need to combine vectors and data frames to create a holistic data set. The cbind() and rbind() are powerful functions, allowing us to combine vectors and data frames efficiently. Let’s start by creating two vectors, having first and last names of players, by using following
