Julia,
my preferred way of plotting spatial data
is to use spatial classes as provided by package(sp).
library(sp)
library(maps)
pts <- data.frame(lng = seq(10,15,1),
lat = seq(45,50,1),
date = seq(2000,2005,1))
# coerce to class SpatialPointsDataFrame
coordinates(pts) <- ~lng+lat
# attribute date is stored in slot data
slot(pts, "data") # equivalent to p...@data
map(xlim = c(8,17), ylim = c(43,52))
points(df)
text(df, labels = d...@data$date)
Cheers,
Rolond
Hello!
I have a dataset with the date and positions - Lat and Long columns
How do I make a scatter plot?
Do I have to cbind the Lat and Long columns?
Any suggestions will be much appreciated!
Thank you
Julia
