blighty: British Isles Coastlines

Description

Function for drawing the coastlines of the British Isles

Usage

blighty(place="set.British.Isles", set=TRUE, grid=FALSE, xlimits, ylimits, xpadding=0, ypadding=0, parcol, parbor, parwdh, sarcol, sarbor, sarwdh, parang, parden, sarang, sarden, tlncol, tlnwdh, grdcol, grdwdh)

Arguments

place

map set - a list of objects to plot - see notes - default - "set.British.Isles"

set

set to FALSE if place is not a standard set of objects - default - TRUE

grid

TRUE or FALSE - places a grid in OS km over the map - default - FALSE

xlimits

vector of limits in OS km in which to draw the map

ylimits

vector of limits in OS km in which to draw the map

xpadding

kms to leave to either side between the edges and map in the x direction - default = 0

ypadding

kms to leave to either side between the edges and map in the y direction - default = 0

parcol

primary area colour - "transparent" for no shading - default - par("bg")

parbor

primary area colour - "transparent" for invisible - default - par("fg")

parwdh

primary area border width - default 1

sarcol

secondary area colour - "transparent" for no shading - default - par("bg")

sarbor

secondary area colour - "transparent" for invisible - default - par("fg")

sarwdh

secondary area border width - default 1

parang

angle of hatching lines for primary areas - default NULL - parden must be set to positive if hatching is to appear - look at polygon for further information

parden

density of hatching lines for primary areas in lines per inch - default - NULL - parden must be set to positive if hatching is to appear - look at polygon for further information

sarang

angle of hatching lines for secondary areas - default NULL - parden must be set to positive if hatching is to appear - look at polygon for further information

sarden

density of hatching lines for secondary areas in lines per inch - default - NULL - parden must be set to positive if hatching is to appear - look at polygon for further information

tlncol

colour of lines for non-area objects - default - par{"fg"}

tlnwdh

width of lines for non-area objects - default = 1

grdcol

colour of grid lines - default - par{"fg"}

grdwdh

width of grid lines - default = 1

Value

blighty.mapinfo in the global environment to give information for north.pointer and map.scale

blighty()		# British Isles coastline
blighty(grid=TRUE)	# British Isles coastline with grid
points(399,91)		# add in Poole OS coords last digit is 1km

blighty(place="set.Scotland")	# Scotland and the Western Isles

text(327, 655, "Edinburgh")

blighty(place="set.Wales")	# Wales and Anglesey

blighty(place="set.Ireland")	# Ireland

blighty(place="set.England", xlimits=c(400,600), ylimits=c(50, 200))
box()			# south of England and the Isle of Wight
			# and the Thames Estuary


blighty(place="set.British.Isles")	# do a plot then add the capital cities
x <- c(532, 327, 317, 118, 157)		# make up two vectors of points
y <- c(181, 672, 175, 385, 529)		# for capital cities

names <- c("London", "Edinburgh", "Cardiff", "Dublin", "Belfast") # vector of names
 
points(x,y, col="red")	# add in the points in red
 
text(x + 20, y, labels=names, adj=0)
			# add some labels displaced by 20km to the right

set.mine <- set.British.Isles$Object[c(1,2,3,87,88)]
blighty(place="set.mine", set=FALSE)
			# specify a custom set of objects here it can
			# be all the coastlines for the main British Isles
			# note how you have to specify the new set in quotes
			# and specify set=FALSE - all else should be as normal

blighty(parcol="gray")	# use a basic shading

blighty("set.Scotland", parcol="blue", parbor="red", sarcol="red", tlncol="green", tlnwdh=3)
			# looks hideous but demonstates some of the shading
			# functions
