ggplot2 graphs are empty

I have troubles trying to use ggplot2 package. All the graphs I got are empty:

ggplot(data=dataa,aes(x=Description, y=RPKM,fill=Condition))+ geom_bar(position="dodge",stat="identity")

File dataa is a piece of a bigger data frame like this:

Description    Tissue    Condition    RPKM
re                  brain       obese       3
re                  brain       Slim         34
re                  brain       Fit           35
re1                brain       Fit            23
re1                brain       obese       34
re1                brain       Slim         67

Do you have any idea what I'm doing wrong?

You are probably plotting to a null device. Try dev.new() to launch a new one. In alternative, if this code is inside a function, you will have to print it explicitly. For example: myplot<-ggplot(...) + geom_bar(); print(myplot).
