Convert a Methylation ExpressionSet from EPIC to 450k Array (DataSHIELD Client Function)

Description

This function subsets a methylation ExpressionSet from an EPIC array (850k probes) to a 450k array or vice versa in a DataSHIELD environment.

Usage

ds.methylation_array_convert(
  eSet_symbol,
  objective_array,
  new.obj = NULL,
  datasources = NULL
)

Arguments

eSet_symbol	A character string representing the server-side symbol of the ExpressionSet object containing either EPIC or 450k array data.
objective_array	A character string specifying the target array type. Can be either "450k" or "epic".
new.obj	A character string specifying the name of the new server-side object created. If NULL (default), the same name as 'eSet_symbol' is used.
datasources	A DataSHIELD connections object containing the information for one or multiple data sources.

Value

A server-side symbol representing the ExpressionSet object containing the subset of probes based on the target array type.

Examples

# Assuming you have a DataSHIELD login and 'eSet' is available on the server
# Convert the eSet from EPIC array to 450k array
eSet_450k_symbol <- ds.methylation_array_convert(eSet_symbol = "eSet", objective_array = "450k")
# Convert the eSet from 450k array to EPIC array
eSet_epic_symbol <- ds.methylation_array_convert(eSet_symbol = "eSet", objective_array = "epic")
