In R, a barplot is computed using the barplot() function.
Here is the most basic example you can do. The input data is a data frame with 2 columns. value is used for bar height, name is used as category label.

# create dummy data
data <- data.frame(
name=letters[1:5],
value=sample(seq(4,15),5)
)
# The most basic barplot you can do:
barplot(height=data$value, names=data$name)
