Split string/factor column

Source: R/df_split_col.R

Given a data frame x, a column name and a naming scheme, the function splits every element in x[[split.col]], using the naming scheme. Next, either a data frame with column names indicating the split parts for each unique value in x[[split.col]] is returned, or, if append=TRUE, this data frame is left-joined with x by split.col.

df_split_col(x, split.col, scheme, delim, append = TRUE)

delim

[character]
Set of characters used to split the entries in the column.
append

[logical(1)]
Should the splitted data be appended to x by split.col? Default is FALSE.
