I am trying to plot vertical bar plots over a map. I went through examples
online but somehow not being able to.
My data is currently in this format:
University| Count | Category | lat | long
Here is the code that I am trying execute:
##-------------------------------------------------------------------------
library(ggplot2)
library(ggmap)
library(ggsubplot)
df1 <- data.frame(
University = c(rep("University1", 4), rep("University2",
4),
rep("University3", 4),
rep("University4", 4)),
Count = sample(1:10, 16, replace = T),
Category = rep(c("A", "B", "C", "D")),
lat = c(rep(10.902469, 4), rep(17.921959, 4), rep(18.606910, 4),
rep(13.202366, 4)),
long = c(rep(76.90020, 4), rep(83.42510, 4), rep(73.87501, 4),
rep(77.62340, 4))
)
india <- get_map("India", zoom = 5)
p <- ggmap(india)
p + geom_subplot(data = df1, mapping=aes(x = long, y = lat, group University,
subplot= geom_bar(aes(x = Category, y = Count, color = Category, stat
"identity"))))
##-------------------------------------------------------------------------
When I run the above code, I get the following error:
Error in get(x, envir = this, inherits = inh)(this, ...) :
could not find function "%:::%"
Is this a bug? I am currently running R 3.0.1.
Thanks & Regards,
