How do I create a simple bar graph from this data where the first column is along the x-axis and the height of the bar should be proportional to the corresponding value in second column.

Till now, I have tried the following:

binData <- read.table("binFile")
costBars = ggplot(binData,aes(x=V1,y=V2))
finalPlot2 = costBars + geom_bar()
finalPlot2

However these commands generate the following error?

stat_bin: binwidth defaulted to range/30. Use 'binwidth = x' to adjust this.
Error in pmin(y, 0) : object 'y' not found

    What you need is stat="identity"

    For example, this line

    ggplot(data=binfile, aes(x=V1, y=V2)) + geom_bar(stat="identity")

    gives me this plot

    enter image description here

    Is that what you’re after?
