df_split_by | R Documentation |
Split a data frame by groups into subsets or data panel. Very
similar to the function df_nest_by()
. The only difference is
that, it adds label to each data subset. Labels are the combination of the
grouping variable levels. The column holding labels are named "label".
df_split_by( data, ..., vars = NULL, label_col = "label", labeller = df_label_both, sep = c(", ", ":") )
data |
a data frame |
... |
One or more unquoted expressions (or variable names) separated by commas. Used as grouping variables. |
vars |
a character vector containing the grouping variables of interest. |
label_col |
column to hold the label of the data subsets. Default column name is "label". |
labeller |
A function that takes a data frame, the grouping variables,
label_col and label_sep arguments, and add labels into the data frame.
Example of possible values are: |
sep |
String separating labelling variables and values. Should be of
length 2 in the function |
A tbl with one row per unique combination of the grouping variables. The first columns are the grouping variables, followed by a list column of tibbles with matching rows of the remaining columns, and a column named label, containing labels.
