Dear all,
I need to insert an small icon in each bar of a barplot, in a specific
location (depending on bar's value).
For example: the first bar has X value of 5. I need to insert an icon at X
value 3. The second bar has X value of 8. I need to insert an icon at value
7.
I have both vectors with values for the bars and values where I should
include the icon.
Hi Igor,
You can probably display your "icons" with the rasterImage function in
the base graphics package. In order to position the images, you will
need the return value from barplot:
barpos<-barplot(...)
giving you the x positions, and your "values where I should include the
icon" for the y positions. You will have to specify the position of the
images in "bottom left/top right" coordinates, so this will depend upon
the size of the image.
