Hi everyone,
I determined the presence of three types parasites in a passerine bird over two years. I would like to create a bar chart that shows the proportion infected on the y and year/parasite on the x such that each type of parasite is grouped together (single label) and a bar for each year . This would show if there have been changes in the prevalence of a the parasite over two years. This is the summary data: Parasite Year Infected Leukocytozoon 2009 0.2564 Plasmodium 2009 0.3846 Hemoproteus 2009 0.0769 Leukocytozoon 2010 0.0562 Plasmodium 2010 0.7079 Hemoproteus 2010 0.3034 Any 2009 0.5128 Any 2010 0.7753 Here are rows 86 to 92. Band and site were recorded differently each year but these are not part of any calculation. Year band site Plasmodium Hemoproteus Leukocytozoon Any 86 2010 2341-06597 1041 1 1 1 1 87 2010 2341-06598 1041 0 0 0 0 88 2010 2341-06599 1042 1 1 0 1 89 2010 2341-06600 1042 0 1 0 1 90 2009 6443 SOSP0901 0 0 1 1 91 2009 6444 SOSP0902 0 1 0 1 92 2009 6445 SOSP0903 0 0 0 0 Any suggestions on how to create this plot would be greatly appreciated.
