r - How to Create loop for plotting in dabestr?

I am using dabestr for plotting estimation plots, for a single variable I succeed, but I want to create a batch of plots with the for loop and it not work.

library(dabestr)
plot(dabest(iris, Species,  Petal.Width, idx = c("setosa", "versicolor"), paired = FALSE))

I want to plot Sepal.Length, Sepal.Width, Petal.Length, Petal.Width in a for loop. Would anyone help? Thank you!

The issue is not with the for statement, it's with the dabest function. It's made to only accept column names as given in .data so a string with the column name doesn't work...

After digging a bit, I found this answer very helpful for dplyr related problems with variable names.

library(dabestr)
library(ggpubr) # for ggarrange

to_plot <- c("Sepal.Length", "Sepal.Width", "Petal.Length", "Petal.Width")
plots <- lapply(to_plot, function(co){
  plot(dabest(iris, Species, UQ(rlang::sym(co)), idx = c("setosa", "versicolor"), paired = FALSE))
})

ggarrange(plotlist = plots, nrow = 2, ncol = 2)

Note that UQ(rlang::sym(my_string)) is doing the magic here. This yields the following plot.
