plotting bar graphs in R using ggplot2

I have a data frame called toplot_noind as shown below. > toplot_noind Chang.1 Chang.2 Chang.3 Chang.4 Chang.5 Chang.6 Chang.7 Chang.8 18 150.3 84.61 31.45 11.08 -0.19 -57.83 -88.63 -98.39 I would want to use this data frame to plot a bar graph using ggplot2. I do not need the column names: Chang.1, Chang.2, etc., in the graph. I want these 8 values 150.3, 84.61, ..., -98.39 to appear on the y-axi
