Deron Eriksson updated SYSTEMML-529:
------------------------------------
Description:
Column names are a useful form of metadata that describe the data in the
columns of a CSV file. This information can be very useful when outputting
information about the data, for example when printing out to the console.
When reading from a CSV file with a header to a matrix variable, it would be
nice if the matrix object contained the column names.
For example, for a read such as the following:
{code}
m = read("m.csv", format="csv", header=TRUE);
{code}
It would be nice if the user could obtain the column names with something such
as:
{code}
c = colnames(m);
print("column names: " + c);
{code}
and see something such as:
{code}
column names: location, gender, age
{code}
