Is it possible to locate a star glyph on a scatterplot using ggplot2?

This R code outputs 5 star glyphs but I can't control their location: 

stars(mtcars[1:5, 1:4], key.loc = c(6, 0.5),
      main = "Example of 4 glyph stars", labels= NULL, flip.labels = FALSE)

I want to position each glyph according to 5 pairs of (x,y) coordinates on a scatterplot using ggplot2.

Not sure how to do it using ggplot, but stars has the capability to control the location by using locations. See below:

x_s <- 1:5
y_s <- 1:5
loc <- data.frame(x = x_s, y = y_s)

stars(mtcars[1:5, 1:4], key.loc = c(5, 0), locations = loc,
  main = "Example of 4 glyph stars", labels = NULL, flip.labels = FALSE)
