Sorting by columns might seem tricky, but this can be made easy by either using R’s built-inorder()function or by using a package. R’s Built-InOrder()Function You can for example sort by one of the dataframe’s columns. You order the rows according to the values that are stored ...
The first argument you pass to subset() is the name of your dataframe, cash. Notice that you shouldn't put company in quotes! The == is the equality operator. It tests to find where two things are equal and returns a logical vector. Interactive Example of the subset() Method In the ...
