Examples

## Plotting Vietnam in Southeast Asia:
#library(sp)  # "plot"
#library(gadmSEA)  # "vietnam"
#library(dplyr)  # "mutate" function and the " %>% " pipe operator
### defining colors:
#rgb2 <- function(...) rgb(..., max = 255)
#blue   <- rgb2(200, 237, 255)
#grey   <- rgb2(225, 225, 225)
#yellow <- rgb2(253, 252, 235)
### the map:
#plot(vietnam, xlab = "longitude (decimal degree)", border = NA,
 #             ylab = "latitude (decimal degree)", bg = blue)
#mcutils::datasets("gadmSEA") %>%
 # as.data.frame(stringsAsFactors = FALSE) %>%
 # setNames("country") %>%
 # mutate(col = ifelse(country == "vietnam", yellow, grey)) %$%
 # invisible(purrr::map2(country, col, ~ plot(get(.x), col = .y, add = TRUE)))
 # axis(1); axis(2); box(bty = "o")

## Plotting some countries in southeast Asia:
#library(sp)  # for "plot"
#library(gadmSEA) # for the countries
#library(magrittr) # for " %$% " and " %>% "

#rgb2 <- function(...) rgb(..., max = 255)
#blue   <- rgb2(200, 237, 255)
#grey   <- rgb2(225, 225, 225)
#yellow <- rgb2(253, 252, 235)

### the map:
#plot(vietnam, xlab = "longitude (decimal degree)", border = NA,
#               ylab = "latitude (decimal degree)", bg = blue,
#              xlim = c(68, 146), ylim = c(-11, 54))
