Try the following code which I modified from January at how do I map (on a geographical map) data in R just given the US Zipcodes:
pdf("myzipcodes.pdf")
library(maps)
map(database="usa")# national boundaries
library(zipcode)
data("zipcode")
myzips <- c("22313","83701","32301")
selected <- zipcode[ zipcode$zip %in% myzips, ]
points( selected$longitude, selected$latitude, pch= 19, cex= 2 )
text( selected$longitude, selected$latitude, selected$zip, pos=3, cex= 2 )
dev.off()
You provided two phony zip codes so I added a couple real ones.
In RStudio you can also export a plot as a PDF file using the ‘export’ menu.
