siarplotdata() for one group #6

Closed VirginiaMorera closed 1 year ago

VirginiaMorera commented 9 years ago

Version: 4.2 I detected a possible bug in siarplotdata() for the single group version. Aparently takes the column of the grouping variable as the first isotope so siarplotdata(modeldemo, iso=c(1,2) produces bugexample1 In my example N is the 1rst isotope, and siar is plotting it as the second, and "Code" as the first. As a consequence, the second isotope, C, gets plotted as the third like in siarplotdata(modeldemo, iso=c(2,3) bugexample2 The sources are correctly plotted, and the axis values seem to correspond the the actual isotopic values of the sources, the problem is only in representing the consumers.

This is also an issue with only two isotopes, but it disappears in the multigroup version.

great example illustrating. i will take a look when i get a chance, but its going to be April at the earliest I'm afraid.

Haven't had time to try it yet but this is probably fixed in version 4.2.2 as it fixes some bug regarding data from a single group of consumers?

AndrewLJackson commented 9 years ago

it might not be. i will try take a look tomorrow. Is this happening with the demo files too? https://github.com/AndrewLJackson/SIAR-examples-and-queries/tree/master/siar-mixing-models

AndrewLJackson commented 9 years ago

this works for me in the demo_script.r file using the geese1.txt consumer file in place of geese2.txt. Can you check it works for you and i will close this issue. thanks.

Can't remember now how I fixed, or if I did. But in any case, SIAR has stopped being maintained since there is another package with the same functionality but better, updated modelling techniques, plotting functions and so on. Check out https://github.com/andrewcparnell/simmr for more info, code and vignettes.

Have you solved the problem of the bug in one group? I have the same problem when i used stable isotope mixing model in R.
