Thanks for taking a look.
As you can see from my (reduced) example below, I am drawing on counts
and then asking bin to aggregate.
My hunch is that ylab() somehow gets over-ridden in the collaboration
implicit in geom_histogram.
Accordingly, any comment that illuminates the actual mechanics invoked
by this (and how to examine them) would be much appareciated.
vals<-c(-2.601,-2.073,-1.341,-1.126,-1.022,-0.847,-0.839,-0.791,-0.790,-0.683,-0.572,-0.556,-0.538,-0.454,-0.394,-0.342,-0.313,-0.184,-
0.138,0.302,0.307
,0.364,0.796,0.830,0.992,1.029,1.305,1.334)
cnts<-c(186.8,541.0,221.5,191.2,545.6,317.9,375.6,335.5,154.4,199.1,305.1,302.4,179.2,164.8,155.0,281.4,158.6,560.3,208.6,164.1,157.2
,505.2,1282.9,181.6,273.0,315.3,166.9,222.8)
qdata<-as.data.frame(cbind(vals,cnts))
qplot(vals,weight=cnts,data=qdata,binwidth=.29,main="test")+ylab("NEW")

histogram
Hi Steven,
The basic example works:
qplot(rnorm(100)) + ylab("Bin Counts")
Please post a reproducible example that illustrates the problem you are having.
Best,
Ista
