Hi
First post and a relative R newbie....
I am using the vioplot library to produce some violin plots. I have an input CSV
with columns off irregular length that contain NAs. I want to strip the NAs out
and produce a multiple violin plot automatically labelled using the headers. At
the moment I do this
Code:?
ds1 = read.csv("http://www.lecturematerials.co.uk/data/spelling.csv")
library(vioplot)
y6<-na.omit(ds1$y6)
y5<-na.omit(ds1$y5)
y4<-na.omit(ds1$y4)
y3<-na.omit(ds1$y3)
y2<-na.omit(ds1$y2)
y1<-na.omit(ds1$y1)
vioplot(y6, y5, y4,y3,y2,y1,horizontal=TRUE, names=c("Y6",
"Y5","Y4","Y3","Y2","Y1"), col
= "lightblue")
Two queries:
1. Is there a more elegant way of automatically stripping the NAs, passing the
columns to the function along with the header names??
2. Can I easily add the sample size to each violin plotted??
thanks
mike

However, after loading it I realized that I had no way of replicating what you are seeing, because you didn't provide that file (or even something that resembles it. It's rather unclear how you wanted this information presented. -- David. David Winsemius Alameda, CA, USA
Never let it be said there's only one way to do a thing:
require(ggplot2)
require(dplyr)
#create a sample dataset
dat <- data.frame(y1=sample(c(1:10,NA),20,replace=TRUE),
y2=sample(c(1:10,NA),20,replace=TRUE),
y3=sample(c(1:10,NA),20,replace=TRUE))
# convert from wide to long
dat <- melt(dat)
# add the counts as a label
dat <- merge(dat,
group_by(dat,variable) %>%
summarise(lab=paste0('n=',length(na.omit(value)))))
# do the plot
ggplot(dat,aes(x=variable,y=value)) +
geom_violin() +
geom_text(aes(y=max(value,na.rm=TRUE)/2,label=lab))
# apologies to David Winsemius for directing this answer to him, I'll work
out how to use email one day.

But require() should not be used interchangeably with library()... the return value from require() should always be tested. -- Sent from my phone. Please excuse my brevity.
