str(species.factor)
Factor w/ 81 levels "Acer_platanoides_Bl",..: 12 12 55 55 76 76 52 52
67 67 ...
str(minmax)
int [1:162] 6163779 7262127 6163779 7422941 6163779 6644861 6163779
6644861 6163779 7262127 ...
That is, my factor is the species listed two times each
Acer_platanoides_Bl Acer_platanoides_Bl Sorbus_aucuparia_Bl
Sorbus_aucuparia_Bl..... more species
and minmax lists min_sp1 max_sp1 min_sp2 min_sp2......
Here an image of my plot (with more elements included, but you can see
the black squares in the centers of each box...)
This is not a black square, it is line which indicates median, which is to
be expected in a boxplot. If you really want to remove it use
medlty=0
in your plot call as indicated in bxp help page.

I have a factor which is species and the variables are a few sites
where this
species live.
When I plot:
plot(species.factor, minlatitudemaxlatitude)
the plot produced is automatically a boxplot which shows the range of
the
species (which is what I want).
This fact (a boxplot from the "plot" function) suggests that the
objects you are plot()-ting are of some class for which there is a
specific plot method. What do these commands return:
str(species.factor)
str(minlatitudemaxlatitude) # ?
However, in the thin box which is produced by each species, there is
a small
black square in "center position" of the box. Is it possible to
remove this.
Have tried to include bxp(par(medpch=NA)) without success.
Thanks!
