ggplot: dotplot with column index on y-axis and its value as dot size VS a second column value on x-axis

Question

I have a data table that looks like this

#       A1  A2  A3  B1  B2  B3
#   1:  1   1   3   1   5   5
#   2:  2   1   3   2   6   9
#   3:  3   2   1   3   8   11
#   4:  4   2   1   4   9   15

Now I would like to use ggplot to plot on the x-axis the values of column B1, B2 and B3, using the corresponding value in column A1, A2 and A3 for the dot size and get something like this dot plot (please note, in the picture the y axis is reversed, the lables should be 3>1, 2=2 and 1>3)

How can I do it?

Answer 1

Something like this:?

df=read.table(text="
       A1  A2  A3  B1  B2  B3
     1   1   3   1   5   5
     2   1   3   2   6   9
     3   2   1   3   8   11
     4   2   1   4   9   15",header=T)

ggplot(gather(df[,4:6]),aes(x=key,y=value)) + 
  geom_point(aes(size=gather(df[,1:3])$value)) + 
  theme_bw() + theme(panel.grid.major = element_blank(),
                     panel.grid.minor = element_blank())
