Hello Omer,
If you want violin plots for different categories, I would suggest lattice 
solution. For start;

https://www.r-bloggers.com/violin-and-boxplots-with-lattice-and-r/

Search terms: lattice, bwplot, panel.violin will help you find more examples.

Many thanks Jeff! I knew it would require a loop approach, so I will now 
explore that with the code you suggested.

Your request is outside of the scope of ggplot2. There are a variety of ways to 
achieve your ends, but they all involve loops of one sort or another... e.g.

wsheds <- unique( merged$Wshed )
for ( w in wsheds ) {
print( ggplot( data=subset( merged, w == Wsheds ), ... ) ) }

I have become quite used to embedding my R code into rmarkdown files which 
allows me to mix multiple graphs, tables and text commentary in one place. 
RStudio makes this about as easy as it can be,  though support for that IDE is 
off topic here.

Re: [R] violin plot help

2017-05-17 Thread Jim Lemon

Hi Omar,
You may want to try subsetting your data and then passing each morsel
to be plotted as a violin plot, either as separate calls to ggplot or
directly to a violin plotting routine.

vioplot (vioplot)
violin_plot (plotrix)

Re: [R] violin plot help

2017-05-17 Thread Abdelrahman, Omar (RER)

Thank you, curly quotes got me! I was able to subset the data and produce the 
violin plot. Now, is there a way to generate multiple plots separately (no 
facets)? With so many levels of each variable, I am trying to avoid doing it 
iteratively. Neither ggplot2 books nor web searches have yielded anything (so 
far). 
Also I want a violin for each year within Geo. I did try to specify year with 
the following:
ggplot () +
facet_grid (PARAMETER ~Wshed~year, scales="free_y") +
geom_violin (data=subdf, aes(x=Geo, y=RESULT, fill=Geo))

which yielded
-Error in combine_vars(data, params$plot_env, cols, drop = params$drop) : 
  At least one layer must contain all variables used for faceting

Also tried:
ggplot () +
facet_grid (PARAMETER ~Wshed, scales="free_y") +
geom_violin (data=subdf, aes(x=Geo~year, y=RESULT, fill=Geo))

Do I need to specify "year(date)"; I loaded lubridate?

Please use reply-all or equivalent to keep the list in the conversation. I 
don't do private online consultation.

Your example suggested you did not know the difference, but your error suggests 
a completely different expression triggered the error, so all the more reason 
to give us an example that we can run to trigger the same error. 

Items B and C are recommendations to read the help pages for those syntax 
elements. You should already have read enough of an introduction to R to have 
encountered the use of the question mark to bring up the help pages. If not, 
please do.

Your example suggested you did not know the difference, but your error suggests 
a completely different expression triggered the error, so all the more reason 
to give us an example that we can run to trigger the same error.

Items B and C are recommendations to read the help pages for those syntax

[R] violin plot help

2017-05-16 Thread Abdelrahman, Omar (RER)

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.
