R help - Jun 2006 - barplot dataframes w/ varying dimensions

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.

barplot() requires the 'height' argument to be a vector or matrix, so
you need to coerce the data frame:

  barplot(as.matrix(DF))

or

  barplot(as.matrix(DF), beside = TRUE)

depending upon the format you prefer.

Hi

something like
> tab
      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


barplot(as.matrix(tab), beside=T, legend.text=T)
