partition_dataset: Partition synthetic dataset to training and test set

In Melissa: Bayesian clustering and imputationa of single cell methylomes

Description

Partition synthetic dataset to training and test set

Usage

partition_dataset(
  dt_obj,
  data_train_prcg = 0.5,
  region_train_prcg = 0.95,
  cpg_train_prcg = 0.5,
  is_synth = FALSE
)

Arguments

dt_obj	Melissa data object
data_train_prcg	Percentage of genomic regions that will be fully used for training, i.e. across the whole region we will have no CpGs missing.
region_train_prcg	Fraction of genomic regions to keep for training set, i.e. some genomic regions will have no coverage at all during training.
cpg_train_prcg	Fraction of CpGs in each genomic region to keep for training set.
is_synth	Logical, whether we have synthetic data or not.

Value

The Melissa object with the following changes. The 'met' element will now contain only the 'training' data. An additional element called 'met_test' will store the data that will be used during testing to evaluate the imputation performance. These data will not be seen from Melissa during inference.
