how to plot a data frame into R

I have a txt filde in which is storedthe information related tu clusters: 

PID   Cluster
123    1
234    1
2345   2 
......

I can read the field and then, I've generated a data frame. I want to plot the data in bars, that indicates for example the number of patients in y axe and the cluster in x axe. In this case I want two bars with values 2 and 1 respectively. Thank you

In base R:

patients = data.frame(PID = c(123, 234, 2345), Cluster = c(1,1,2))
pat.table = with(patients, table(Cluster))
barplot(pat.table)

Using ggplot2

require(ggplot2)
ggplot(patients, aes(x = factor(Cluster))) + geom_bar() + scale_x_discrete("Cluster")
