The first row of the table contains column names and the
first column contains row names, and the rest of the matrix
contain numeric values.
Numbers are written in textual format. The following forms are recognized:
"[+-]1", "[+-]1.0", "[+-]1.0e7". Infinities or NaN are not supported.
Missing values are supported: missing cells have an 'NA' string.
Column separator is \t and line separator in \n. The first row with
column names must not be a valid numeric row.
This is to prevent interpreting a matrix file with missing column and row
names as valid input.
The value of the first cell (position 1, 1) is not used,
but the cell must be present, i.e. the whole table must
also form a rectangular matrix. |
