It somewhat depends on how the warnings are being produced - some functions may have specific options for suppressing / outputting warnings, for example.
The easiest approach is probably as elaborated HERE.
A quick example:
test.R
options(warn = 0)
log <- file('log.out', open = 'wt')
sink(log, type = 'message')
warning('warning!')
warning('Achtung!')
warning('Aviso!')
warning('Atenção!')
sink(type = 'message')
close(log)
Now execute it:
Rscript test.R
log.out
Warning message:
warning!
Warning message:
Achtung!
Warning message:
Aviso!
Warning message:
Atenção!
By the way, setting options(warn = 0) just ensures that warnings will be issued. Setting it to options(warn = -1) would mean that warnings are not even reported anywhere.
