Hi,
I am trying to select values from a list where my bolean (true/false) list would indicate to select the column.
Something like.
List.Select(datalist, listwithtruefalsevalues)
Quite common in R and other languages, you select rows from you dataframe based on an array of true/false values.
Hope its clear.
Kind regards, Steve.

How to create test data using DAX!
Solved! Go to Solution.
See if this help
let
DataList= {1,2,3,4,5},
Listwithtruefalse = {true,false,true,true,false},
Mergedlist=List.Zip({DataList,Listwithtruefalse }),
Desiredlist = List.Transform(
List.Select(Mergedlist, (d)=>d{1}=true),(d)=>d{0})
in
Desiredlist
since you have 2 lists of the same lengths, why not use subscript to pick up responding values like this,
let
DataList= {1,2,3,4,5},
Listwithtruefalse = {true,false,true,true,false},
Desiredlist = List.Accumulate({0..List.Count(Listwithtruefalse)-1}, {}, (s,c)=>if Listwithtruefalse{c} then s&{DataList{c}} else s)
in
Desiredlist
Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension! |
DAX is simple, but NOT EASY! |

Thanks, I found a way to do it, turns out, it's the same approach as you suggest. So it probably makes sense 😃
