List-class-leftovers {IRanges} | R Documentation |
IMPORTANT NOTE - 9/4/2014: This man page is being refactored. Most of the things that used to be documented here have been moved to the man page for List objects located in the S4Vectors package.
The only thing left here is the documentation of the stack
method for List objects. In the code snippets below, x
is a List object.
stack(x, index.var = "name", value.var = "value")
:
As with stack
on a list
,
constructs a DataFrame
with two columns: one for the
unlisted values, the other indicating the name of the element from
which each value was obtained. index.var
specifies the column
name for the index (source name) column and value.var
specifies the column name for the values.
The List class defined and documented in the S4Vectors package.
