scenarios when applying multiple ggplot layers dynamically with variable aesthetics in R
I need some guidance on Could someone explain I can't seem to get I tried several approaches but none seem to work... I'm working with an scenario while trying to dynamically add multiple layers to a `ggplot` object based on user input. Specifically, I want to allow the selection of different aesthetics for each layer, but I keep running into an behavior when I attempt to render the plot. Here's what I've done so far: I have a dataset with `x`, `y`, and `group` variables, and I want to plot different types of point shapes and colors based on user choices. I've set up a list of aesthetics to loop through, but upon executing, I receive the behavior `behavior: Aesthetics must be either length 1 or the same as the data (3): shape`. Here's a simplified version of my code: ```r library(ggplot2) # Sample dataset data <- data.frame(x = rnorm(10), y = rnorm(10), group = rep(1:2, each = 5)) aesthetics_list <- list( list(shape = 16, color = 'red'), list(shape = 17, color = 'blue') ) base_plot <- ggplot(data) for (i in seq_along(aesthetics_list)) { aes <- aesthetics_list[[i]] base_plot <- base_plot + geom_point(aes(x = x, y = y, shape = aes$shape, color = aes$color), data = data[data$group == i, ]) } print(base_plot) ``` In this setup, the behavior is thrown because I am trying to map the aesthetic parameters directly from the list but it seems ggplot expects them to be defined for the entire dataset. I've tried wrapping the aesthetics in `I()` or using `aes_string()`, but I need to get it to work. How can I correctly apply these dynamic aesthetics for multiple layers without running into this limitation? I'm using R version 4.1.0 and ggplot2 version 3.3.5. My development environment is Ubuntu. Any help would be greatly appreciated! This issue appeared after updating to R 3.11. What's the best practice here? I'm working in a Windows 11 environment. Any advice would be much appreciated. What am I doing wrong? I'm developing on Windows 11 with R.
