I am trying to produce multiple violin plots by 3 categorical variables, each violin representing 1 year worth of data. The variables are:
Watershed (7 levels: county canals) Geography (5 levels: west; central; east; mouth; bay) Parameter (8 levels: water quality chemical parameters) Year (25 levels: 1992-2017) I want to produce 1 plot for each Parameter-Watershed subdivided into Geography with a violin for each year. I used facets with the following code (not by year): ggplot () + facet_grid (PARAMETER ~Wshed, scales="free_y") + geom_violin (data=merged, aes(x=Geo, y=RESULT)) I do not want facets, they crowd the information so it is unreadable. I just started with R this week and have not been able to figure out the foreach protocol, or any other loop protocol. I tried to subset the data to do it iteratively with the following code: subdf<-subset (merged, Wshed = "AC") but got an error: Error: unexpected input in "subdf=subset (merged, Wshed == "" Any help would be greatly appreciated.
