We can't either.

You supplied a screenful of email but __no reproducible code__ exhibiting an
error we can reproduce.  Nobody can help you based on what you wrote here.

| the function called is a c++ function defined as:
| // [[Rcpp::export]]
| SEXP runNormalisation(DataFrame mEd, std::string samfile, int nwrks, 
| float e_lm, int chunk)
| 
| never had any problems with that.
| 
| today it started to crash with the above error.
| Weirdly, this happens only when I call the R function, like:
| NormaliseEdges(g.Edges, file.SAM)
| Error: not compatible with requested type
| Called from: runNormalisation(miniEdges, fileSAM, numWrks, edgesProb, grain)
| 
| if I simply call the c++ function it works fine
| retEdges <- runNormalisation(miniEdges, file.SAM, 1, 0, 0)
| 
| I double-checked that 'miniEdges' is a data.frame (and it is); also, it 
| has always been.
| 
| 
| I fear this might have something to do with other modifications in other 
| files, that somehow affected the whole? is it possible?
| I don't see any other error!
