list2DF
Quickly Make Data.frame From List of Vectors
Description
Makes a simple data.frame from a list of vectors without checking
for valid names or column types.
Usage
list2DF(x = list(), nrow = NULL)
Arguments
| x |
A list of vectors to become the columns of a data.frame.
The vectors should have unique names, but this is not checked.
|
| nrow |
The desired number of rows: all vectors in x are repeated
or truncated to this length. If NULL, then it is set to the maximum
of zero and the lengths of vectors in x.
|
Details
The vectors in x are passed through rep_len(x, nrow),
and rep_len strips the attributes, includeing classes, from
most things. It processes factors properly, but it converts objects such as
Dates and POSIXct objects into numeric vectors, and it converts matrices into vectors.
If names(x) is NULL then the column names of the resulting
data.frame are empty strings, "". Duplicate column names
on a data.frame can confuse some functions.
Value
returns an nrow-row data.frame whose columns are derived from the vectors in x
