What's not working? Trying to "dodge" point ranges

[adam.l...@pnc.com]

Hi group,

Two things are happening when I run this. First, the dodging doesn't seem to occur. The points and point ranges overlap, although the legend indicates the grouping. Secondly, for some reason, it's not recognizing "ymax." Any ideas? Thanks.

pd.range<-structure(list(rr = c(1L, 2L, 3L, 4L, 5L, 6L, 7L, 8L, 9L, 10L,
11L, 12L, 13L, 1L, 2L, 3L, 4L, 5L, 6L, 7L, 8L, 9L, 10L, 11L,
12L, 13L), exp = c(1e-07, 1e-06, 1e-05, 1e-04, 4e-04, 9e-04,

Points and lines are treated as one-dimensional, i.e., they don't have
a width. So you need to set a width in the position_dodge() call, like
this:

ggplot(pd.range,aes(as.factor(rr),exp))+
geom_pointrange(aes(colour=as.factor(rho),ymin=min,ymax=max),
position=position_dodge(width=0.5))

Best,
Ista

For some reason the ymax warning is actually coming from geom_point...

ggplot(data=pd.range)+ 

#geom_point(aes(x= as.factor(rr),y= exp, colour=as.factor(rho)),position="dodge")+ 

geom_pointrange(aes(x=as.factor(rr), y=exp, colour=as.factor(rho), ymin=min, ymax=max), position=position_dodge(width=0.5))

#GET PLOT, NO WARNING

ggplot(data=pd.range)+ 

geom_point(aes(x= as.factor(rr),y= exp, colour=as.factor(rho)),position="dodge") #+ 

#geom_pointrange(aes(x=as.factor(rr), y=exp, colour=as.factor(rho), ymin=min, ymax=max), position=position_dodge(width=0.5))

#GET PLOT, WARNING

ymax not defined: adjusting position using y instead

ggplot(data=pd.range)+ 

geom_point(aes(x= as.factor(rr),y= exp, colour=as.factor(rho)),position="dodge")+ 

geom_pointrange(aes(x=as.factor(rr), y=exp, colour=as.factor(rho), ymin=min, ymax=max), position=position_dodge(width=0.5))
