How do I keep the original order in ggplot2

I have the following code:

df <- data.frame(Days = days,Temperature = temp)
pl <- ggplot(df,aes(x=Days,y=Temperature)) + geom_point()
print(pl)

When I try running this code it shows the days in alphabetical order instead of the index order (Mon,Tue,Wed,Thu,Fri). How can I change it to the correct order?

After a little bit of searching I found a built-in English-weekday-abbreviation object (in correct order) by installing the DescTools package. Using

data.frame(Days=factor(days,levels=DescTools::day.abb), ...)

seems to be the most principled way to do this (I can't think of an easy way to do this with weekday name abbreviations from another locale ...)

The below code works:

library(ggplot2)

days <- c("Mon","Tue","Wed","Thu","Fri")
temp <- c(21, 24, 34, 23, 23)

df2 <- data.frame(Days2=factor(days,levels=unique(days)), Temperature2 = temp)

pl2 <- ggplot(df2,aes(x=Days2,y=Temperature2)) + geom_point()
print(pl2)

It produces the below graph: enter image description here
