Plot Bar Chart in R - Year issue

I'm working with an shinyapp that creates bar charts according to some user input. Let's say that the user has selected this df

type;year
a;2001
b;2001
a;2002
b;2006
a;2007
b;2007

when i plot the data, it won't show the years 2003to 2005, of course, Because it has no values. So, if i plot them, there will be no gap between these years and it will look wrong.

Any ideas how to set the x-axis value even if it has no data in it?

I've tried to look for something similiar but couldn't find it.

You just need to wrap year column with as.numeric

library(ggplot2)

#sample plot
ggplot(df, aes(x = as.numeric(year), fill = type)) +
  geom_bar()

Output plot is enter image description here

Sample data:

df <- structure(list(type = c("a", "b", "a", "b", "a", "b"), year = c("2001", 
"2001", "2002", "2006", "2007", "2007")), .Names = c("type", 
"year"), row.names = c(NA, -6L), class = "data.frame")
