search for: amount_cattle

...concerning the barplot (barchart lattice) of a dataframe. I work with the attached dataframe. When I try to plot this dataframe I only get two rows plottet. When I try to plot the whole dataframe, there is message, that it is 'height' must be a vector or a matrix. On the y-axis, the "amount_cattle" should be displayed and on the x-axis the "year" and the "country" so that I can compare the amount over the years in each country. Each country on the x-axis needs 4 bars (2000-2003). I hope you can help me. Thanks a lot geophagus -- View this message in context:...
