Dear all, I have a matrix called combine86 which looks as follows:
> combine86 Sim Mean Obs Mean Sim Sum Obs Sum AMAZON 1172.0424 1394.44604 553204 659573 NILE 262.4440 164.23921 67973 41881 CONGO 682.8007 722.63971 205523 214624 MISSISSIPPI 363.0758 142.59883 124535 49054 AMUR 143.5857 89.30434 36040 22594 PARANA 702.3793 388.03030 162952 89635 YENISEI 208.1396 174.52722 83464 70509 OB 197.0399 162.82697 79013 63991 LENA 118.1100 77.49638 48307 32161 NIGER 374.8258 212.25714 66719 37145 ZAMBEZI 500.0000 485.87610 57000 54904 YANGTZE 358.4172 256.80246 58422 41602 For each of the rivers (which are the row names of this matrix), I wish to plot a bar for Simulated Mean and another for the Observed Mean. So far I've only been able to get R to stack the bars (using 'barplot) on top of one another, which isn't really what I want! I was hoping more for a pairing of bars (one 'Sim' and one 'Mean') followed by a gap, then the next pair of bars for the next river, a gap, and so on. Is this possible to do in R? If so, how?!
