Call.graphics error in ggplot

General
#1

Am working with a shapefile while doing my spatial data analysis when i try to use ggplot to plot the sapefile this is the error it throws

library(ggplot2)
lf<- fortify(ke_counties,region = "CONST_CODE")#Convert spatial data
head(lf)
p<- ggplot() +
  geom_polygon(data=lf,
               aes(x=long,y=lat,group=group,fill=order),#the order is the column in the data
               color="black",size=0.25) +
  coord_map()#this adds coordinates in the map
p
lf

The Error that coem up yet my data frame is okey

Error in .Call.graphics(C_palette2, .Call(C_palette2, NULL)) : 
  invalid graphics state

Do you have a MWE of the ke_counties object?

Also, FYI, the ggplot2 manual recommends:

Rather than using this function, I now recommend using the broom package, which implements a much wider range of methods. fortify may be deprecated in the future.

whats mwe cant figure that quite well

#4

The main challenge that am dealing with here its that this is spatial data

#5

can it convert polygon or a shapefile into a data frame coz thats what i want to achieve

#6

like which function allows us to convert a spatial polygon into a data frame in ggplot2

#7

An MWE is a minimal working example, so that we know how ke_counties looks like.

It is possible to plot spatial data, and there are different ways.
I usually use the sf package.
You can read in a shape file with x <- st_read("file.shp")
and plot the file with ggplot() + geom_sf(data=x)

As a side note, here we call an MWE a REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.

If you've never heard of a reprex before, you might want to start by reading this FAQ:
