Hi
I have a column in my data file which is "X/Y". With '/' I want to
emphasize that values are the ratio of X over Y.
Problem is that in the following command for a violin plot, I am not able
to specify that '/' even with double quotes.
p <- ggplot(mydata, aes(x=W, y="X/Y")) + geom_violin(trim=FALSE)
However, if I change that column to "Y" and use
p <- ggplot(mydata, aes(x=W, y=Y)) + geom_violin(trim=FALSE)
Then the plot will be correctly shown.
Any ideas for that?
I haven't tried, but I'd expect back quotes would work:
ggplot(mydata, aes(x=W, y=`X/Y`))
That's the normal way to quote a name in R.
