You were clearly mistaken.
dataframe$column is almost the same as dataframe[["column"]], except that the $
does partial matching. Both of these "extract" a list element.
A data frame is a list where all elements are vectors of the same length. A
list is a vector where each element can refer
Hi All,
I thought dataset$variable is the same as dataset["variable"]. I tried the
following:
> str(ZWW_Kunden$Branche)
chr [1:49673] "231" "151" "151" "231" "231" "111" "231" "111" "231" "231"
"151" "111" ...
> str(ZWW_Kunden["Branche"])
'data.frame':49673 obs. of 1 variable:
$
2 matches
