Changing radius in ggmap

[hditt33]

Hi! I am using your package in combination with ggmap and I really like it. I only have a problem that when I adjust the radius the pies disappear completely. Is the radius change not compatible with ggmap somehow? If so, is there another way to change the size of the pies?

Best, Hannes

any reproducible example?

Thank you for the quick reply!

Here is an example:

library(ggplot2) library(ggmap) library(scatterpie)

data=data.frame(lat=c(52,52,51.5),long=c(4.1,5.5,6),radius=c(5,10,13),A=c(0.2,0.2,0.2),B=c(0.8,0.8,0.8))

map=get_map(location=c(3,50,7,54),source="google")

ggmap(map)+geom_scatterpie(data=data,aes(x=long,y=lat),cols=c("A","B")) # without radius

ggmap(map)+geom_scatterpie(data=data,aes(x=long,y=lat,r=radius),cols=c("A","B")) # with radius

the value is just too large, try:

ggmap(map)+geom_scatterpie(data=data,aes(x=long,y=lat,r=radius/100),cols=c("A","B"))

Great! Thank you very much!
