fitlm on timetable: error message

I try to run fitlm on a time table. I checked dependent and independent variables and got following outputs

ans =

      2.5017
      1.8388
      1.8418
      2.0561
      5.0655

ans =

     17.4631
     19.5389
     16.5552
     15.0083
     11.4510

But when I try to run fitlm, I got a following error message:

Error using classreg.regr.FormulaProcessor (line 384)
The model formula contains names not recognized as predictor or response names.

Error in classreg.regr.LinearFormula (line 48)
            f = [e-mail](varargin{:});

Error in classreg.regr.TermsRegression.createFormula (line 699)
                    formula = classreg.regr.LinearFormula(modelDef,varNames,'',intercept,link);

Error in LinearModel.createFormula (line 1388)
            formula = classreg.regr.TermsRegression.createFormula(supplied,modelDef, ...

Error in LinearModel.fit (line 1224)
            model.Formula = LinearModel.createFormula(supplied,modelDef,X, ...

Error in fitlm (line 121)
model = LinearModel.fit(X,varargin{:});

Error in AAA (line 247)
lm2 = fitlm(T,'VAR1~VAR2');

Please advise.

Something seems wrong in running fitlm on timetable.

[Walter Roberson]

What are the names of the variables in the timetable ?

[alpedhuez]

VAR1 and VAR2

Answer 1

[Walter Roberson]

fitlm() specifically tests for table objects, and timetables are not tables. fitlm is defined for tables, datasets, numeric arrays, and tall arrays, but not defined for timetables.

You can use timetable2table() to convert your timetable for use with fitlm.

[alpedhuez]

Should be fixed in the future release.

[Walter Roberson]

You can file an enhancement request. It is not a bug because not all methods that apply to tables also apply to timetables.
