Question

I am trying to generate the map of U.S. in which each state can have one of the following colors:

EScolors <- c(\"#7aad42\",\"#4a77bb\",\"#f7931e\",\"#d3dfbd\

Let ggplot2 do the hard work for you:

library(ggplot2)

read.table(text="State.Code   region St_Abbr Num_Estab  colors
1          1   alabama      AL     13123 #f7931e
3          4   arizona      AZ     18053 #f7931e
4          5   arkansas      AR      9154 #4a77bb
5          6   california      CA    143937 #787878
6          8   colorado      CO     21033 #d3dfbd
7          9   connecticut      CT     17176 #f7931e", 
           stringsAsFactors=FALSE, header=TRUE, comment.char="") -> df

usa_map <- map_data("state")

gg <- ggplot()
gg <- gg + geom_map(data=usa_map, map=usa_map,
                    aes(long, lat, map_id=region),
                    color="#2b2b2b", size=0.15, fill=NA)
gg <- gg + geom_map(data=df, map=usa_map,
                    aes(fill=colors, map_id=region),
                    color="#2b2b2b", size=0.15)
gg <- gg + scale_color_identity()
gg <- gg + coord_map("polyconic")
gg <- gg + ggthemes::theme_map()
gg
