Hi,
I am new to this forum and new to awk.
I have a file that contains 2 columns.
Heres an example of what it looks like:
10 +
20 +
40 +
50 -
70 -
So the file is tab-delimited. What I want to do is add 10 to column 1 whenever column 2 is + and substract 10 from column 1... (1 Reply)

Hi,
I have a table to be imported for R as matrix or data.frame but I first need to edit it because I've got several lines with the same identifier (1st column), so I want to sum the each column (2nd -nth) of each identifier (1st column)
The input is for example, after sorted:

dbix::class::resultsetcolumn
DBIx::Class::ResultSetColumn(3) User Contributed Perl Documentation DBIx::Class::ResultSetColumn(3)NAME
DBIx::Class::ResultSetColumn - helpful methods for messing
with a single column of the resultset
SYNOPSIS
$rs = $schema->resultset('CD')->search({ artist => 'Tool' });
$rs_column = $rs->get_column('year');
$max_year = $rs_column->max; #returns latest year
DESCRIPTION
A convenience class used to perform operations on a specific column of a resultset.
METHODS
new
my $obj = DBIx::Class::ResultSetColumn->new($rs, $column);
Creates a new resultset column object from the resultset and column passed as params. Used internally by "get_column" in
DBIx::Class::ResultSet.
as_query
Arguments: none
Return Value: [ $sql, @bind_values ]
Returns the SQL query and bind vars associated with the invocant.
This is generally used as the RHS for a subquery.
next
Arguments: none
Return Value: $value
Returns the next value of the column in the resultset (or "undef" if there is none).
Much like "next" in DBIx::Class::ResultSet but just returning the one value.
all
Arguments: none
Return Value: @values
Returns all values of the column in the resultset (or "undef" if there are none).
Much like "all" in DBIx::Class::ResultSet but returns values rather than result objects.
reset
Arguments: none
Return Value: $self
Resets the underlying resultset's cursor, so you can iterate through the elements of the column again.
Much like "reset" in DBIx::Class::ResultSet.
first
Arguments: none
Return Value: $value
Resets the underlying resultset and returns the next value of the column in the resultset (or "undef" if there is none).
Much like "first" in DBIx::Class::ResultSet but just returning the one value.
single
Arguments: none
Return Value: $value
Much like "single" in DBIx::Class::ResultSet fetches one and only one column value using the cursor directly. If additional rows are
present a warning is issued before discarding the cursor.
min
Arguments: none
Return Value: $lowest_value
my $first_year = $year_col->min();
Wrapper for ->func. Returns the lowest value of the column in the resultset (or "undef" if there are none).
min_rs
Arguments: none
Return Value: $resultset
my $rs = $year_col->min_rs();
Wrapper for ->func_rs for function MIN().
max
Arguments: none
Return Value: $highest_value
my $last_year = $year_col->max();
Wrapper for ->func. Returns the highest value of the column in the resultset (or "undef" if there are none).
max_rs
Arguments: none
Return Value: $resultset
my $rs = $year_col->max_rs();
Wrapper for ->func_rs for function MAX().
sum
Arguments: none
Return Value: $sum_of_values
my $total = $prices_col->sum();
Wrapper for ->func. Returns the sum of all the values in the column of the resultset. Use on varchar-like columns at your own risk.
sum_rs
Arguments: none
Return Value: $resultset
my $rs = $year_col->sum_rs();
Wrapper for ->func_rs for function SUM().
func
Arguments: $function
Return Value: $function_return_value
$rs = $schema->resultset("CD")->search({});
$length = $rs->get_column('title')->func('LENGTH');
Runs a query using the function on the column and returns the value. Produces the following SQL:
SELECT LENGTH( title ) FROM cd me
func_rs
Arguments: $function
Return Value: $resultset
Creates the resultset that "func()" uses to run its query.
