Here is one way by redefining 'options' so you can check for 'width'
and then call the 'options' in 'base':
> options <- # define 'options' in Global
+ function(...)
+ {
+ args <- list(...) # get arguments
+ if ('width' %in% names(args)){ # see if 'width' is in them
+ .caller <- sys.calls() # get where called from
+ if (length(.caller) == 1) # called from command line
+ .caller <- "Rgui"
+ else .caller <- as.character(.caller[[length(.caller) - 1]])[1]
+ cat("width being changed:", args[['width']], "Called from",
.caller, '\n')
+ }
+ base::options(...) # call the real options
+ }

> options(width = 123) # test at command line
width being changed: 123 Called from Rgui
> f.myfunc <- function() options(width = 456) # within a function
> f.myfunc()
width being changed: 456 Called from f.myfunc

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.
