Deconcatenate delimited column values in a data.frame
deconcat_df2(x, column, split = "[,; |/]+", blank = "", ...)data.frame or compatible object
character vector with one or more colnames(x)
that should be de-concatenated.
character pattern used by strsplit() to split
multiple values in each column.
character string used to replace entries that
would otherwise be zero-length as returned by strsplit().
additional arguments are ignored.
This function deconcatenates delimited values in a column
of a data.frame by calling strsplit() on column values,
and repeating values in all other columns to match lengths()
following strsplit().
This function includes a correction for cases where strsplit()
would otherwise return zero-length entries, and which would
otherwise be dropped from the output. From this function,
zero-length entries are replaced with blank="" so these
rows are not dropped from the output.
