Hi,   I have a dataset with many variables, named as it follows:  street_density, landuse_mix, street_connectivity, deprivation   I would like to automatically rename them as x1= street_density, x2=landuse_mix, x3=street_connectivity, x4=deprivation.   I am looking for an easy way to do this for many variables simultaneously.   Thanks! ...
