I created a world map using the code below. Right now, it shows the countries that have data. I want to be able to see zoomed out version of the world map in plot view. Insight on this issue will be appreciated. Thank you in advance.
library(tmap)
tmap_mode("plot")
v7<-tm_shape(Omap)+
tm_polygons("X", palette= "Reds",title="Country",
colorNA="white",
showNA=FALSE,
border.alpha = 0)+
tm_shape(worldmap2) +
tm_borders(col = "grey",lwd = 0.5)+
tm_layout(bg.color = "white")+
tm_layout(frame = TRUE,outer.margins=c(.05,0,.05,0), inner.margins=c(0,0,.02,0), asp=0,
legend.outside=FALSE,
legend.position=c("right","bottom"),
"Number", title.position = c('right','top'))+
tm_legend(show=TRUE)+
tm_view(set.view = c(lon = 0, lat = 0, zoom = 0))
# legend.stack = "horizontal")
v7
