In jakobbossek/re: Utility Functions Missing in Base R

Split string/factor column

Description

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.

Usage

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

Arguments

x	[data.frame] Source data frame.
split.col	[string] Column name of column used for splitting.
scheme	[string] Single string encoding the names and types of the split parts. E.g. “group{c}/problem{c}_n{i}_m{i}/algorithm{c}_pc{r}”. Passed down to decode_scheme.
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.

Value

Modified data frame.
