Q:

R project: maps package

I am new to R so this may be stupid to ask. I am using maps package to plot point in US map. However the map that appears after using:
 map("state", lwd=1, col="#cccccc")

is very small in size. How can I increase the size of the map. I went through the manual but nothing I found could solve my issue. 

A:

Try outputting the map to a file, for example:
png("example.png",width=60,height=60,units="in",res=75)
map("state", lwd=1, col="#cccccc")
graphics.off()

creates a 60"x60" map at 75 dpi. You can change the parameters of the function you use to output the graphic to specify the size and resolution.
