Hello,
I need plot map using ggplot()
I use such code:
library("ggplot2")
library(cshapes)
cshp.data <- cshp()
map <- cshp.data[cshp.data$COWCODE==369,]
map_mp<- list(
geom_polygon(aes(long, lat, group = group), data = map, fill = "grey70",
colour = "grey60", inherit.aes = FAL
Hi:
As Duncan noted, your approach is at best inefficient. Consider the
following example:
# Generate some fake data:
x <- data.frame(x = rpois(10, 5), y = rnorm(10))
# Generate a list where each component is a row of x
l <- split(x, rownames(x))
# verify it's a list
l
# class of each list compo

I have a list of vectors of length 2, each representing a point in 2-space,
and each of which I wish to plot on the current plot.
In a loop, I assign the x and y coordinates of the current element of the
list to variables 'x' and 'y' respectively, then make a call to plot as
follows:
