Now, we can use the duplicated () function on the data frame as shown below: # remove duplicated rows based on name df <- df [!duplicated (df [,c ("name")]),] The code above utilizes the “!” operator, in order to indicate that we do not want to keep the duplicated rows based on values found within the name column of the data frame. If your dataset consists of a single column, skip this step. For old Browsers (<ie9), that do not support the native methods filter and indexOf you can find work arounds in the MDN documentation for filter and indexOf. Columns can be atomic vectors or lists. expand() and tidyr::grid_expand() will return an object with a row for each unique value of the joint distribution of unique values across one or more vectors. combinations. grid and strsplit and is much more complex/convoluted. Share. This can be done, for example, using tidyr::expand_grid(). The problem is that there are 2 rows of c with behavior=2 (1-12-2020 and 1-16-2020) as you said, but in the final data frame with your method, there are 4 rows of c with behavior=2. anyDuplicated (iris) Example 4. Never converts strings to factors. It would be neat if it disambiguated the column names like data. Inside the for-loop, add check if the items in the list exist in the array myFinallist. I repeat the original data frame df 3 times, whilst adding one column where the number in the column indicated the repetition. It is paired with nesting () and crossing () helpers. n <- 14 lapply (0: (2^n-1), FUN=function (x) head (as. in Column D (the formula column), and check E from the drop down list. e.
