Dear colleagues,

I want to create a density curve with individual dots.

The model is from this manuscript:

I have found a few tutorials, and also one nice package (ggridges) to plot this.

Here is my result. However, this package does only work with a y-value (e.g. 2 categories), but does not work if I just want to plot it for a single gorup.

My questions are:

- Can I plot single density curves using the ggridges package? I do not want multiple behind each other.
- Can I plot an ordinary density curve using ggplot2 including a jitter plot for individual dots?

Thank you very much

```
# dataframe
set.seed(1234)
df <- data.frame(
sex=factor(rep(c("F", "M"), each=200)),
weight=round(c(rnorm(200, mean=55, sd=5),
rnorm(200, mean=65, sd=5)))
)
# Packages
library(ggplot2)
library(ggridges)
ggplot(df, aes(x = weight, y = sex)) +
geom_density_ridges(jittered_points = TRUE)
```
