[R] barplot dataframes w/ varying dimensions

[Albert Vilella]

Hi all,

I would like to do a barplot of a dataframe like this one:

       alfa   beta gamma delta
 qwert   56.5  58.5 56.5  58.5
 asdfg   73.0  73.0 43.0  73.0
 zxcvb   63.0  63.0 43.0  63.0
 yuiop   63.0  63.0 43.0  63.0

with the labels of the rows and columns.

I would like to have something that works for dataframes with varying
dimensions, and so far I haven't found any way to do it.

What would be the best way to do that?

Thanks in advance,

Albert.
