R plotting table of incomplete dates

Novice R question: given a number of observations over a range of dates, e.g.,

obs <- as.Date(c("2001-08-02","2001-08-02", "2001-08-02","2001-08-03", 
                "2001-08-04", "2001-08-04", "2001-08-07", "2001-08-07"))

I can plot the frequencies of observations over time with

plot(table(obs))

enter image description here

However, how can I generate a table plot from obs that includes all intermediate missing dates (i.e., "2001-08-05", "2001-08-06") showing zero frequency?

You should probably use the hist function instead, it covers cases like these.

hist(obs, breaks='day', format = "%d %b", freq=TRUE)

Try this:

obs <- c(obs, seq(min(obs), max(obs), 1))
plot(table(obs) - 1)
