R: Iterator over Rows of a Data Frame Stored in a File
iread.table
R Documentation
Iterator over Rows of a Data Frame Stored in a File
Description
Returns an iterator over the rows of a data frame stored in
a file in table format.
It is a wrapper around the standard read.table function.
Usage
iread.table(file, ..., verbose=FALSE)
Arguments
file
the name of the file to read the data from.
...
all additional arguments are passed on to the
read.table function. See the documentation for
read.table for more information.
verbose
logical value indicating whether or not to print the
calls to read.table.
Value
The file reading iterator.
Note
In this version of iread.table, both the read.table
arguments header and row.names must be specified. This is
because the default values of these arguments depend on the contents of
the beginning of the file. In order to make the subsequent calls to
read.table work consistently, the user must specify those
arguments explicitly. A future version of iread.table may remove
this requirement.
