Today I practiced R on Sololearn! This time I went over ways to group data, such as the by and tapply functions. I went over their differences, their similarities, and ultimately their place in manipulating data. Next time I will be reviewing everything we have learned!
Today I practiced R on Sololearn! This time I started working on data. I discussed methods of filtering results from a DataFrame. I also briefly discussed a correlation matrix, used to find the dependence between columns. Next time I will be grouping data!
Today I practiced R on Sololearn! This time I went over basic operations with DataFrames. All of the basic operations used for DataFrames can be used in statistics. I went over using these methods to find certain rows in a DataFrame. Next time I will be working with data!
Today I practiced R on Sololearn! This time I went over getting the statistics of our dataframes. We have to start with the basic concepts before we get to the exciting parts, stay tuned. Next time I will be going over basic operations with statistics!
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!
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
