Hi again,
As a follow up, does anybody know how to fix the following error?
It seems that I can use a "weight" parameter in geom_violin, but I am able to
figure out what is the problem with the following code.
> library(ggplot2)
> mydata <- read.csv('test.csv', header=T,row.names=1)
> mydata
V1 V2 V3
P1 73.6 50 R
P2 75.2 20 R
P3 6.5 5 R
P4 41.4 10 C
P5 5.4 10 C
P6 18.8 5 C
> p <- ggplot(mydata, aes(x=V3, y=V1)) + geom_violin(trim=FALSE, weight=V2)
Error in layer(data = data, mapping = mapping, stat = stat, geom = GeomViolin,
:
object 'V2' not found
>
>
> wg <- as.factor(mydata$V2)
> p <- ggplot(mydata, aes(x=V3, y=V1)) + geom_violin(trim=FALSE, weight=wg)
> p + geom_dotplot(binaxis='y', stackdir='center', dotsize=1)
`stat_bindot()` using `bins = 30`. Pick better value with `binwidth`.
Error: Aesthetics must be either length 1 or the same as the data (1024): weight
Run `rlang::last_error()` to see where the error occurred.

Subject: Weighted violin chart
Hi,
I would like to know if it is possible to plot a weighted violin chart with R.
Currently, I have
> library(ggplot2)
> mydata <- read.csv('test.csv', header=T,row.names=1)
> mydata
V1 V2 V3
P1 73.6 50 R
P2 75.2 20 R
P3 6.5 5 R
P4 41.4 10 C
P5 5.4 10 C
P6 18.8 5 C
> p <- ggplot(mydata, aes(x=V3, y=V1)) + geom_violin(trim=FALSE)
> p + geom_dotplot(binaxis='y', stackdir='center', dotsize=1)
I would like to use V2 as the weight vector. Any idea about that?
Regards,
Mahmood
