getAttrb - Solved
Hi,
I changed
INTEGER(getAttrib(shape,mkChar("nParts")))[0]
to
INTEGER(getAttrib(shape,mkString("nParts")))[0]
and now it works fine.

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

PBSmapping and shapefiles
Hi,
Is there a way, preferably with R, to read shapefiles and transform
them in a format that I could then use with package PBSmapping?
I have been able to read such files into R with maptools' read.shape
and plot it with plot.Map, but I'd like to bring the data to
PBSmapping and plot from there. I also looked at the package
shapefile, but it does not seem to do what I want

map issues
...s of some help. So after reading the help on this i tried to convert the Map object to an sp object. But I keep failing.

How to mask or escape "=" in Windows command prompt?
I have defined a function with several arguments and have it stored in the
.RData file.
The 'function head' is defined as follows
EstimALIConc
<-function(sdname,SZ,W,farea,watri,biomodel,start.part=1,nparts=20,method=c("optim","DEoptim"))
{
[ blah-blah-blah ]
(function body doesn't matter)
}
Then I call Rscript:
e:> rscript --restore -e
"EstimALIConc('17-aug',27.8,5,1,watri,biomodel,1,100,method='DEoptim');warnings();"

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

How to signal the end of the table?
I am using a "for" loop to read a table row by row and I have to specify how
many records are there in the table. I need to read row by row because the
table is huge and the memory not large enough for the whole table.:
number.of.records=100
fp=file("abc.csv","r")
pos=seek(fp, rw="read")
for (i in 1:number.of.record){
current.row=scan(file=fp,
