I need to change the labelling for my floats (Page numbers/sections/figures/tables/schemes) into Figure S1, Table S1, Scheme S1, ... (for Supporting Infortmation of a journal).
For Figures and Tables, I found this code, which works perfectly fine:
\renewcommand{\thepage}{S\arabic{page}}
\renewcommand{\thesection}{S\arabic{section}}
\renewcommand{\thetable}{S\arabic{table}}
\renewcommand{\thefigure}{S\arabic{figure}}
However, if I try to do the analogy with the scheme environment from the chemmacros
package
\renewcommand{\thescheme}{S\arabic{scheme}}
I get the following error in the log-file:
Command \thescheme undefined.
I'm not that an expert in code reading, so I did not manage to get the right label description for the scheme environment out of the chemmacros package code. Any suggestions to get this renaming to work is highly appreciated!
