Draw histograms per row over multiple columns in R

Question

I\'m using R for the analysis of my master thesis I have the following data frame: STOF: Student to staff ratio

    HEI.ID   X2007 X2008 X2009 X2010 X2011 X2         


        

Answer 1

Here's a solution in lattice:

require(lattice)
barchart(X2007+X2008+X2009+X2010+X2011+X2012 ~ HEI.ID,
         data=HEIrank11,
         auto.key=list(space='right')
         )
