writing polygons/segments to shapefiles (.shp) or other ArCGIS compatible file
I am not sure a previous e-mail reached the list (no mail aknowledgement from R-boundle etc.). The question was how to write polygon
or segment coordinates into a shapefile set or any other ArcGIS supported format. The library shapefiles seems to do something but
the documentation is a bit beyond of my mind.... and I cannot get the meaning of the functions write**** and its application to the
case

FW: Drawing maps of UK
Hi Guys
Thanks for this! As I am a beginner, I bet I'm running into some really
basic problems. Using the example from the Map2poly function in
maptools:
try <- read.shape("euadmll.shp")
mappolys <- Map2poly(try)
# this produces 14 warnings() of the type:
# 1: level 2 circularity at 62 in: .mtlbuild(.mtafters(r1), rD) # etc #
14: From next release, default hole handling

Greetings:
I would like to kindly ask for a little help. The rough code is:

quote="\"", dec=".",na.strings = "NA"))
nc=read.shape("astae.shp", dbf.data=TRUE, verbose=TRUE)

dot density maps
Dear All,
In the moment i'm using the map and maptools package to read shapefiles
and display the maps.
I'm looking for the possibility to draw points (randomly positioned or
positioned according to a grid) into the polygons instead of filling the
polygons with colors.
For example:
a map (shapefile) with 10 countries, 15 points in the polygon of country
A, 20 points in the

Re: using shapefile as owin
My sincerest apologies, as this is a very elementary problem, but I have
searched through archives and FAQs and on the web, and I am at the end of my
own resources.
I need to do analysis of a spatial point process occuring with four
counties, using spatstat. I've had no trouble importing the shapefiles, but
I can't seem to figure out what I need to do in order to use the boundary as

sum of variables in function
Dear R users,
Probably, this is quite a simpe question, but I do not find the proper way
to obtain want I need. To explain the problem, I constructed a simple
example.
Suppose I have the following function:
try1<-function(x){
y<-x[1:2]
z<-x[3:4]
y[1]*(z[1]+z[2])+y[2]*(z[1]+z[2])
}
This function will be part of a for loop. This is what I like to obtain for
every k:

Splitting vector into individual elements
Is there a means to split a vector into its individual
elements without going the brute-force route for arguments
to a predefined function call?
offred.rgb <- c(1, 0, 0) * 0.60;
## Brute force style
offred.col <- rgb(offred.rgb[1],
offred.rgb[2],
offred.rgb[3],
names = "offred")

grep help needed
Hi,
In another thread ("PBSmapping and shapefiles") I asked for an easy
way to read "shapefiles" and transform them in data that PBSmapping
could use. One person is exploring some ways of doing this, but it is
possible I'll have to do this "manually".
With package "maptools" I am able to extract the information I need
from a shapefile but it is

Dirty Rotten Hack. (reversing tickmarks on axes?)
I feel dirty.
I have some graphs I'm building to communicate chargeback rates and service
usage for our backup system here at the University of Florida. These come
down to daily data points on a graph of number-of-bytes transferred and
stored.
Since we chargeback on the same basis (price per MB this, price per KB that)
the same chart with a different scale can be used to communicate bytes

from long/lat to UTM
Hi:
Is there any function in R which can convert the
long/lat to UTM(Universal Transverse Mercator)?
There are quite a few converters on Internet.
However, the interface is designed as input->output
which I can not convert lots of locations at the same
time.
Another question is whether there is a function in R
which can tell the time zone from the location's
lat/long?
Thank you!

map2poly - map lat/long cannot be unconstrained?
Using the maptools function "map2poly" I have created a map/polylist object
- a map of the Great Lakes. My goal is to passively plot additional data on
this map. Unfortunately I am not able to change (distort) the relative scale
of the axes for the map, and so the sample points do not line up correctly
on the map.
In the code below, notice that I have set the same axis ranges on each

Dear all,
We are doing some research about the time series analysis of NDVI, and
we found the NDVITS package which is a very great tool.
Unfortunately when we run it, after TimeSeriesAnalysis it asks to enter
