Beside barchart with ggplot2

The basic chart functionality in R makes it relatively simple to produce a bar chart with data columns side-by-side, using the beside flag. For instance, this code:

test1 <- c(2,4)
test2 <- c(4,5)
data <- data.frame(test1, test2)
barplot(
    as.matrix(data), 
    cex.lab = 1.5, 
    cex.main = 1.4, 
    beside=TRUE
    )

Produces this chart:

I would like to produce a similar chart with ggplot2, but the geom_bar function does not have a beside flag. Can a similar bar chart be produced with ggplot2?

Try this:

library(reshape2)
data$ID <- as.factor(1:nrow(data))
ggplot(melt(data, id='ID'), aes(variable, value, fill=ID, group=ID)) + 
geom_bar(stat='identity', position='dodge')
