Dear R Users,

I am trying to users gsub to remove multiple cases of square brackets and their
different contents in a character string. A sample of such a string is shown
below. However, I am having great difficulty understanding regexp syntax. Any
help is greatly appreciated.

"tree STATE_286000 [&lnP=-12708.453945423369] = [&R]
