I whould like to check every single value in my dataset if it’s a NaN or not in julia  
and put it in an other dataset like in the photo

in pyhton they use for that  
“”" df.isna()“”"

See the package [GitHub - JuliaData/DataFrames.jl: In-memory tabular data in Julia](https://github.com/JuliaData/DataFrames.jl) It’s hard to give any better answer than that to such a low effort question. For advice on how to get better quality help through asking better targeted questions, I’d strongly advise reading this thread: [Please read: make it easier to help you](https://discourse.julialang.org/t/please-read-make-it-easier-to-help-you/14757)
