Read several data.frame sets
Reads a text file in table format and creates a data frame from it. The
file may contain several sets, separated by empty lines. The function adds an
set to indicate to which set each row
the name of the file which the data are to be read from.
Each row of the table appears as one line of the file. If it
does not contain an absolute path, the file name is
relative to the current working directory,
a vector of optional names for the variables. The default is to use "V" followed by the column number.
A data frame (
data.frame) containing a representation of the
data in the file. An extra column
set is added to indicate to
which set each row belongs.
A know limitation is that the input file must use newline characters
native to the host system, otherwise they will be, possibly silently,
misinterpreted. In GNU/Linux the program
dos2unix may be used
to fix newline characters.
There are several examples of data sets in
