I am working with ggplot2
and want my geom_points
to have individual shapes based on dataframe rows.
data <- read.csv(my_csv_path) #
plot <- ggplot(data = data) + # in this file I have shape numbers (17 or 21) for each csv row.
geom_point(aes(shape = shape), color = "grey20")
Each row has individial shape and I want to draw based on it. My output always draws triangles, based on csv file.
Any ideas ?
Thanks !
Hopefully this will work with your data. If not, do paste a sample of the data using dput
. scale_shape_identity
applies the shape numbers from the dataframe:
library(ggplot2)
library(dplyr)
tibble(shape = 1:5, x = 1:5, y = 1) %>%
ggplot(aes(x, y, shape = shape)) +
geom_point(size = 10, colour = "grey20") +
scale_shape_identity()
