function = importfile not working in APP DESIGNER

Hello guys, another day, another odd issue with my favorite app APP DESIGNER.

I am working on a app which should load a data file from my PC and do a first preprocesing. I just need ti to delete some rows in the file so it wouldn't be so heavy.

For my funktion I am used the basic one which could be created by MATLab itself behind the import data tool.

 methods (Access = private)
                        function R = importfile(filename, dataLines)
%IMPORTFILE Import data from a text file
%  BOOK1 = IMPORTFILE(FILENAME) reads data from text file FILENAME for
%  the default selection.  Returns the data as a table.
%
%  BOOK1 = IMPORTFILE(FILE, DATALINES) reads data for the specified row
%  interval(s) of text file FILENAME. Specify DATALINES as a positive
%  scalar integer or a N-by-2 array of positive scalar integers for
%  dis-contiguous row intervals.
%
%  Example:
%  Book1 = importfile("C:\Users\staryk\Desktop\Book1.csv", [1, Inf]);
%
%  See also READTABLE.

% Import the data
R = readtable(filename, opts)

                end

Rest of the code is there just to open a window and load the data. Last part of code is there just to show me in command window if the process did something or not (and guess what, it doesn't).

                    end
    
        % Button pushed function: LButton
        function LButtonPushed(app, event)
           [file,path,~] = uigetfile({'.csv'}); % open the dialog box, 
           
                 N = file; %create variable with the name of the document
                 app.EditField.Value = N; % show document name in text filed
           
           filename = [path file]; %combine path and name 
           
           A = R(app)

             
        end

This is the errors I am having....

this is the dataset i am using: https://drive.google.com/drive/folders/1nCXV5Stf-5oMKg3asAsr2PF0YbLflIs3?usp=sharing

Please be kind and try to explain the stuff to me because I might be dumb.

Whole code so you can just copy and try it by yourself ...

Syntax for setvaropts might be incorrect.

I tried to use rectangular brackets as in your code, and it didn't work on the basic example from here. Maybe try with these { }.

[Karel Starý]

Nope, it wasn't it. Thnkas for try...

[Cris LaPierre]

I get a different error when I try to run your code:

Undefined function 'R' for input arguments of type 'working'.

Error in working/LButtonPushed (line 81)

A = R(app)

Error while evaluating Button PrivateButtonPushedFcn.

Can you share you app? You can attach it using the paperclip icon.
