Private function to select Gene with DGSA object

Usage

# S3 method for DGSA_object
geneSelection(data_object, gen_select_type, percent_gen_select, na.rm = TRUE)

Value

A geneSelection object. It contains: the full_data without NAN's values, the control tag of the healthy patient, the matrix with the normal space and the matrix of the disease components.

Arguments

data_object

DGSA object information

gen_select_type

Option. Options on how to select the genes to be used in the mapper. Select the "Abs" option, which means that the genes with the highest absolute value are chosen, or the "Top_Bot" option, which means that half of the selected genes are those with the highest value (positive value, i.e. worst survival prognosis) and the other half are those with the lowest value (negative value, i.e. best prognosis). "Top_Bot" default option.

percent_gen_select

na.rm

logical. If TRUE, NA rows are omitted. If FALSE, an error occurs in case of NA rows. TRUE default option.

Examples

# \donttest{
DGSA_obj <- DGSA(full_data, survival_time, survival_event, case_tag, na.rm = "checked")

geneSelection_object <- geneSelection(DGSA_obj, gen_select_type ="top_bot",
                                      percent_gen_select = 10)# }
