r - remove all words that start with "@" from a string -

-

how can remove words start "@" string?

for example, "@agnezmo on @airasia airbus a320-216 fleet @ninetologymy livery -- 9m-ahg cc: @agnesmonicaent @agnezone http://t.co/hfxwuqq2oq"

i have string "on airbus a320-216 fleet livery -- 9m-ahg cc: http://t.co/hfxwuqq2oq"

try s input:

gsub("@\\w+ *", "", s)

giving:

"on airbus a320-216 fleet livery -- 9m-ahg cc: http://t.co/hfxwuqq2oq"
