missing value where TRUE / FALSE needed

[HANANEMIFTAH]

I don't have any NA in my data but I have this error and I don't understand the meaning

Error in if (var < 0) { : missing value where TRUE / FALSE needed
De plus : Warning message:
In .checkInitialValues(dist, start, modelMatrixList, weights, Y, :
unnamed initial values found! They will be used as they are.

Thanks

Can you include the code that throws this error?
