use R::YapRI::Base;
## WORKING WITH THE DEFAULT MODE:
my $rih = R::YapRI::Base->new();
$rih->add_command('bmp(filename="myfile.bmp", width=600, height=800)');
$rih->add_command('dev.list()');
$rih->add_command('plot(c(1, 5, 10), type = "l")');
$rih->add_command('dev.off()');
$rih->run_commands();
my $result_file = $rih->get_blocks('default')->get_result_file();
## WORKING WITH COMMAND BLOCKS:
my $rih = R::YapRI::Base->new();
## Create a file-block_1
$rih->create_block('BLOCK1');
$rih->add_command('x <- c(10, 9, 8, 5)', 'BLOCK1');
$rih->add_command('z <- c(12, 8, 8, 4)', 'BLOCK1');
$rih->add_command('x + z', 'BLOCK1')
## Create a file-block_2
$rih->create_block('BLOCK2');
$rih->add_command('bmp(filename="myfile.bmp", width=600, height=800)',
'BLOCK2');
$rih->add_command('dev.list()', 'BLOCK2');
$rih->add_command('plot(c(1, 5, 10), type = "l")', 'BLOCK2');
## Run each block
$rih->run_command('BLOCK1');
$rih->run_command('BLOCK2');
## Get the results
my $resultfile1 = $rih->get_blocks('BLOCK1')->get_result_file();
my $resultfile2 = $rih->get_blocks('BLOCK2')->get_result_file();
Example of a module that uses R::YapRI::Base, and R::YapRI::Data::Matrix to
calculate the transpose of the matrix
my $matrix = R::YapRI::Data::Matrix( {
name => 'matrix1',
rown => 3,
coln => 4,
` rownames => ['A', 'B', 'C'],
colnames => ['alpha', 'beta', 'gamma', 'delta'],
data => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12],
});
my $rih2 = R::YapRI::Base->new();
$matrix->send_rbase($rih2);
$rih2->create_block('TRMATRIX', $matrix->get_name());
$rih2->add_command('trmatrix1 <- t('.$matrix->get_name().')', 'TRMATRIX');
$rih2->run_commands('TRMATRIX');
my $trmatrix = R::YapRI::Data::Matrix->read_rbase( $rih2,
'TRMATRIX',
'trmatrix1');
DESCRIPTION
YapRI, is "Yet another perl R interface" developed initially to work with
different blocks of commands.
It run the commands esentially as:
R [options] --file=inputcommandfile > outputresultfile
So the R::YapRI::Base module, create files, put them in a temp dir by default,
open these files, write the R commands to them, execute the files and
store all of them as variables in this object.
INSTALLATION
To install this module type the following:
perl Makefile.PL
make
make test
