Hi List,

This is kind of very simple but I am not able to understand how it works...
I have a sentence like "Even in the mid-west spring is hardly for 3 weeks,
while @south the scenario is different."

There are some more example of the same nature and don't know the source
yet.
What i want to do is remove word after "@"..

Solution i think of.

 1. gsub("@$","",string)  or gsub("@\\","",string)
 2. regex

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

x <- "Even in the mid-west spring is hardly for 3 weeks, while @south the scenario is different."
gsub("@[[:alpha:]]+\\s", "", x)

[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))

Please provide me some guidance. Since* words after @ may have different
length so need some flexible solution*.

Also sorry don't know how to put it in dput().
