Your question seems unclear, and you posted using HTML which makes things even less clear (see the Posting Guide). Sharing data on the making list is much more effective using the dput function as described in [1].
I note that your X values are very different, but your Y and Z values are similar. Do you want to estimate a regression model X( Y, Z ) from your nominal data and replace the X values in your measured data?
