Pretty silly but I can't figure out what I'm doing wrong here:
I have a data.frame
with 2 columns:
df = data.frame(x = rep(1, 20), y = runif(20, 10,20))
I then want to set x
and y
as spatial coordinates so I can plot df
in a bubble plot
. So I try:
coordinates(df) = c("x","y")
But then:
bubble(df)
gives this error:
Error in data.frame(x@data, x@coords) :
arguments imply differing number of rows: 0, 20
For bubble plot to be meaningful, you should probably create a SpatialPointsDataFrame
.
library(sp)
df <- data.frame(x = rep(1, 20), y = runif(20, 10,20))
data <- data.frame(variable = runif(20))
coordinates(df) <- ~ x + y
out <- SpatialPointsDataFrame(df, data)
bubble(out)
library(sp)
set.seed(1)
df = data.frame(x = rep(1, 20), y = runif(20, 10, 20), dummy = rep(0, 20))
coordinates(df) = c("x","y")
bubble(df)
