Dave Mason continues his look at lists in R:
Subsetting the list with single brackets [] for the first element returns “Atlantic”. But if we take a closer look using the str() function, we see R returned the data as a class of type list:
> #Appears to return "Atlantic" as a character class. > division[1] $Name [1] "Atlantic" > #str shows us the return is actually a list of 1 element. > str(division[1]) List of 1 $ Name: chr "Atlantic"
Dave also explains the difference between single brackets and double brackets for list elements.
