[R] is it possible to combine multiple barplots?

[Titus von der Malsburg]

You can use barchart in package lattice.  Here's a rough sketch:

    library(lattice)

    dataA <- rep(1:4, c(3,2,2,4))
    dataB <- rep(1:4, c(5,4,3,2))

    da <- data.frame(table(dataA))
    db <- data.frame(table(dataB))

    da$cond <- "a"
    db$cond <- "b"

    colnames(da)[1] <- "data"
    colnames(db)[1] <- "data"

    d <- rbind(da, db)
    barchart(Freq~data|cond, d)
