Betreff: Re: st: AW: AW: string functions
Thanks a lot for your responses Nick and Martin,
I am only removing the units from labels when it is appropriate to do so
(for example when creating a z-score and using the original variable
label to create a new label for the standardised variable).
Is there a generic way of removing the bracketed units even if they are
not placed at the end of the label, for example "total vit A intake
(mg/day), before pregnancy". Note that I have over fifty different units
(some are 1 word in length, some 2 words and some 3 due to spaces in the
brackets) and I was hoping to not have to list them all using the
subinstr() function.
Many thanks for your suggestions!
