addpoints includes a set of points with a set size and symbol

Description

addpoints given a matrix or data.frame, which must contain fields names 'Lat' and 'Long', these value pairs will be added to the plot generated by plotaus

Usage

addpoints(
  indat,
  inpch = 20,
  incex = 0.2,
  incol = 2,
  intitle = "",
  jit = F,
  wobble = 1,
  refill = T,
  Long = "Long",
  Lat = "Lat",
  txtout = TRUE,
  namecatch = "catch_kg"
)

Arguments

indat	a matrix or data.frame containing, at least, columns with the names 'Long' nad 'Lat'.
inpch	default = 20, but can be changed to any valid symbol
incex	default 0.2, but can be a constant or variable
incol	default 2 (red) but can be any colour or rgb definition
intitle	main top center title, the same as in plotaus; this is mostly useful if the refill variable is set to TRUE
jit	default FALSE. If TRUE it will jitter the outcome by the 'wobble' valriable amount. However, for overlapping points it is often better to use an rgb colour with the last value set to a fraction e.g. incol=rgb(9)0,0,0,1/5)
wobble	the amount to jitter a point id jit = TRUE
refill	default TRUE, refill the land after plotting points.
Long	used to define the longitude field; defaults to 'Long'
Lat	used to define the Latitude field; default to 'Lat'
txtout	logical determines whether the number of points added and \ their range will be printed to the screen; defaults to TRUE
namecatch	is the name of the catch variable; defaults to 'catch_kg'

Value

adds the input points to a map; returns nothing.

Examples

dev.new(height=6.0,width=7.5,noRStudioGD = TRUE)
plotaus()
Long <- c(140,141,142,143)
Lat <- c(-41.1,-41.1,-41.1,-41.1)
indata <- cbind(Long,Lat)
addpoints(indata,incex=1.5)
