Subject: [R] Working with violin plot
Hi
I would like to use the violin plot as described in the manual [1]. In the
example, I see
ToothGrowth$dose <- as.factor(ToothGrowth$dose)
head(ToothGrowth)
On the other hand, my data is a csv file containing some rows and numbers.
Problem is that the following code doesn't work
> mydata <- read.csv('test.csv', header=T,row.names=1)
> mydata
V1 V2 V3 V4
P1 73.6 0.7 74.6 R
P2 75.2 0.7 75.8 R
P3 6.5 0.0 7.3 R
P4 41.4 0.3 39.2 C
P5 5.4 0.1 18.2 C
P6 18.8 0.3 30.3 C
> library(ggplot2)
> p <- ggplot(ToothGrowth, aes(x=V4, y=V1)) + geom_violin()
> p
Error in FUN(X[[i]], ...) : object 'V4' not found
Any idea to fix that?
