Displaying bar plot in R

I am trying to create a barplot with midwest dataset. However, when I run the code, I do not see anything in my plots window

library(ggplot2)
try(data('midwest',package='ggplot2'))
for (s in unique(midwest$state)) {
  state_data = subset(midwest, state == s)
  ggplot(state_data, aes(x=county, y=percprof)) + geom_bar(stat='identity')
}

This is a great opportunity for facetting, rather than using a for loop, if you'd rather have them on one figure. Try:

ggplot(midwest) +
geom_bar(aes(county, percprof), stat = "identity") +
facet_wrap(~state)

You'll have to play with the x axis to get it to read clearly..

You will need to print the object explicitly. If you're using Rstudio, you can flip through the resulting plots using left and right arrow button.

for (s in unique(midwest$state)) {
  state_data = subset(midwest, state == s)
  print(
    ggplot(state_data, aes(x=county, y=percprof)) + geom_bar(stat='identity')
  )
}
