I have some plots I want generate in R: I am using ggplot. When I run the commands below the are drawn and it works fine. When I put them in a loop the plots are not drawn. How do I put the ggplot command into a loop and have the plots be drawn?

D1, D2, D3 are columns in the mydataframe

my_category_col is a factor

I want to put the following three commands into a loop:

ggplot(mydataframe, aes(x = D1, y = my_category_col)) +

geom_density_ridges(aes(fill = my_category_col)) +

scale_fill_manual(values = c("#00AFBB", "#E7B800", "#FC4E07", "purple")) +

theme(legend.position = "none")

ggplot(mydataframe, aes(x = D2, y = my_category_col)) +

geom_density_ridges(aes(fill = my_category_col)) +

scale_fill_manual(values = c("#00AFBB", "#E7B800", "#FC4E07", "purple")) +

theme(legend.position = "none")

ggplot(mydataframe, aes(x = D3, y = my_category_col)) +

geom_density_ridges(aes(fill = my_category_col)) +

scale_fill_manual(values = c("#00AFBB", "#E7B800", "#FC4E07", "purple")) +

theme(legend.position = "none")
