SPVM::R::OP::DataFrame - Data Frame Operations

Description

R::OP::DataFrame class in SPVM has methods for operations for data frame.

Usage

  use R::OP::DataFrame as DFOP;
  use R::OP::Int as IOP;
  use R::OP::Double as DOP;
  use R::OP::String as STROP;
  
  my $data_frame1 = DFOP->data_frame;
  
  $data_frame1->set_col("name", STROP->c(["Ken", "Yuki", "Mike"]));
  $data_frame1->set_col("age", IOP->c([19, 43, 50]));
  $data_frame1->set_col("weight", DOP->c([(double)50.6, 60.3, 80.5]));
  
  my $data_frame2 = DFOP->data_frame;
  
  $data_frame1->set_col("name", STROP->c(["Jonh"]));
  $data_frame1->set_col("age", IOP->c([25]));
  $data_frame1->set_col("weight", DOP->c([(double)40.6]));
  
  my $data_frame3 = DFOP->cbind($data_frame1, $data_frame2);
