If you do not know how to use dput then just show some code that creates the
object of interest:

[1] "Even in the mid-west spring is hardly for 3 weeks, while the scenario is
different."
I was puzzled that the documentation suggested this should work, but it only
removed the first letter in the word.
> gsub("@\\w", "", x)
[1] "Even in the mid-west spring is hardly for 3 weeks, while outh the scenario
is different."
And this is how you use dput()
> dput(x)
"Even in the mid-west spring is hardly for 3 weeks, while @south the scenario
is different."
Notice that the output of dput on a character vector is not very revealing. It
is sometimes useful to use this method to shorten a long object:
dput(head(x))
