Hi all,
I'd be grateful for your help. I am a new user struggling with a barplot
issue.

I am plotting categories (X axis) and their mean count (Y axies) with
barplot().

The first call to barplot works fine.

I remove records from the dataframe using final=[!final$varname == "some
value",]

I echo the dataframe and the records are no longer in the dataframe.

When I call plot again however, the X axis still contains the removed
category values albeit with a count of 0.

How can I stop the removed categories appearing in the barplot? Are they
stored globally after the first barplot call?

thanks in advance for your help.
