[R] Barplot - Can't figure it out

[Mulholland, Tom]

barplot(matrix(c(x,y),ncol = 2),beside=T)

Does this help 
 
?barplot notes

height: either a vector or matrix of values describing the bars which
          make up the plot.  If 'height' is a vector, the plot consists
          of a sequence of rectangular bars with heights given by the
          values in the vector.  If 'height' is a matrix and 'beside'
          is 'FALSE' then each bar of the plot corresponds to a column
          of 'height', with the values in the column giving the heights
          of stacked "sub-bars" making up the bar.  If 'height' is a
          matrix and 'beside' is 'TRUE', then the values in each column
          are juxtaposed rather than stacked.
