Removing lower whisker in boxplot to see the effects of the high values

David: 
I set this up and it still seems to plot the same:

maumnf_plot<-boxplot(log_loads~ind,data=nfmaum, horizontal=TRUE, notch=T, outline=FALSE, whisker=0, main="Maumee River Near Future Climate Scenarios", ylab="Log Load",xlab="Climate Scenarios")
maumnf_plot$stats[-1,] (to remove the lower whiskers)
bxp(maumnf_plot)

this does not remove the whiskers....is there something I am missing in bxp?

I said to replace the whisker value with the hinge value:

maumnf_plot<-boxplot(log_loads~ind,data=nfmaum )
# only need the data to get the stats

maumnf_plot$stats[1,] <- maumnf_plot$stats[2,]
# Replaced whisker row with hinge row
# The graphics arguments to bxp need to be in the second call. 
# They won't be carried over from the sats

bxp(maumnf_plot, , horizontal=TRUE, notch=T, outline=FALSE, whisker=0, main="Maumee River Near Future Climate Scenarios", ylab="Log Load",xlab="Climate Scenarios")

Good Afternoon-
I was wanting to alter the boxplot to remove the lower whisker, both the
whisker line and staple just on the lower end. Is there a way to do this?
As my code is currently:
boxplot(log_loads~ind,data=nfmaum, horizontal=TRUE, notch=T, outline=FALSE,
whisker=0, main="Maumee River Near Future Climate Scenarios", ylab="Log
Load",xlab="Climate Scenarios")

If you altered the value in what is passed from `boxplot.stats` to `bxp` so the lower whisker value was the same as the lower hinge value The lower whisker would merge into the hinge. `boxplot` returns those stats-values invisibly, so you just assign to an object name, make your changes and pass back to bxp.

I just want to better see the medians and high end tail.
