re moving parentheses/square brackets from data frame numbers

Dear list,

I am importing data consisting of numbers into dataframes. Some of the
numbers are flanked by parentheses or square brackets. Thus, they are not
recognized as numeric and the corresponding column is of class "factor"
which makes it hard/impossible use in plotting functions.

Is there a way to remove brackets from numbers in a column/row/dataframe?
Oh yes!

But you have not followed this dictum

 	 provide commented, minimal, self-contained, reproducible code

so we can't suggest specific solutions.

Suggest you see

 	?gsub
 	?regexp

HTH,

Chuck
Kind regards,

Stefan
