[R-sig-eco] R-sig-ecology (72-19): Plot question

[Michał Bogdziewicz]

Hi,

whether this is good or not good way to show ecological data I believe
you can create a plot like that using ggplot2 package. Here is the
link to some nice description with examples. Hope that will help:)

cheers,

>> Hi Luis,
>> whatever R code you will end up using, the example image you attached is a good example of how NOT to display ecological data. There is no ecological meaning for the lines connecting the dots (i.e, there is nothing halfway between an ant and a termite), as the x axis shows categorial classes and not a continous parameter such as time to consume prey or prey size etc...
