Hi @Anonymous ,

 

Please try this:

 


dataset$Flag_des <- ifelse(dataset$Flag,"True","False")
output <- dataset

 

 

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQ0VNJRSsxJrQBSbkqxOtFKRkZGQHZBYkpmYh6QEQIWNDY2BrIzUivz4UImJiZAdmV+QSpEaywA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, Name = _t, Flag = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"Name", type text}, {"Flag", type text}}),
    #"Run R script" = R.Execute("# 'dataset' holds the input data for this script#(lf)  #(lf)dataset$Flag_des <- ifelse(dataset$Flag ,""True"",""False"")#(lf)output <- dataset",[dataset=#"Changed Type"]),
    #"""output""" = #"Run R script"{[Name="output"]}[Value]
in
    #"""output"""
