Importing Data – R on Sololearn
Today I practiced R on Sololearn! This time I started a new unit by going over importing data. This video introduces the use of CSVs, which will be important later on. Next time I will be using CSVs with statistics!
Data Structures Review – R on Sololearn
Today I practiced R on Sololearn! This time I went over everything we have learned about data structures: strings, vectors, lists, matrices, and DataFrames. Next time I will be starting a new unit on data analysis
DataFrame Operations – R on Sololearn
Today I practiced R on Sololearn! This time I went over operations DataFrames use, such as sum, mean, and median. I also went over ways to filter results and add new columns. Next time I will be going over everything we have learned!
DataFrame – R on Sololearn
Today I practiced R on Sololearn! This time I went over the DataFrame, which allows you to hold elements of different data types in two dimensions. I also went over how to create a DataFrame and access the columns in one. Next time I will be going over DataFrame operations!
Matrices – R on Sololearn
Today I practiced R on Sololearn! This time I went over the basics of matrices, a two-dimensional data set with rows and columns. I demonstrated how to access individual columns or rows and how to transpose them. Next time I will be going over DataFrames in R!
