For loop plot() vs ggplot() - ggplot() not working?

Question

I am using Iris dataset in R.

I have the following code

for (i in colnames(iris[-5])) { plot(iris$Species, iris[[i]], xlab = 'Species', ylab = `i`) }

This prints out 4 boxplot. I want to do the same in ggplot with the following code

for (i in colnames(iris[-5])) { print(iris %>% ggplot(aes(x = Species)) + geom_col(aes(y = i))) }

When I do this in ggplot, the boxplots look messed up. Is it just my R or am I missing something?

Welcom to the wonderful world of tidyverse non-standard evaluation (NSE). I think geom_boxplot(aes(y = !!sym(i)))) will give you what you want, after correcting the obvious typo in your code. By the way "look messed up" isn't terribly helpful. Please be more specific. — Limey

In this case, you can just change aes(y=i) to aes_string(y=i), and of course, use geom_boxplot instead of geom_col
