[R] colored shading lines
Hi all, it there any possibility to draw colored shading lines of a polygon plot? E.g. plot(polygon_object,col=red,density=10,angle=45) produces only black shading lines within the polygon.

[R] sp: proj4string has no impact
Hi all, I'm faced with a problem applying the sp package: The projection argument in readShapePoly(Shapefile,proj4string=CRS class argument) e.g.: CRS(+proj=aea +lat_1=46 +lat_2=73 +lat_0=60 +lon_0=84 +x_0=0 +y_0=0 +ellps=clrk66 +units=m +no_defs) doesn't have any impact on the plotted object. I also tested the simple example: xy = cbind(x = 2 * runif(100) - 1, y = 2 * runif(100) - 1) plot(SpatialPoints(xy, proj4string = CRS(+proj=longlat)),xlim=c(-1,1),ylim=c(-1,1)) looks exactly like plot(SpatialPoints(xy, proj4string =CRS(+proj=stere +lon_0=98 +over)) or plot(SpatialPoints(xy)) without any projection. What I'm doing wrong? I use the latest versions of sp and rgdal.

[R] Temporal disaggregation using interpolation splines
Hi, this is a newbie question. Would it be able to convert e.g. annual time series of flow data (or an index series) into quarterly data using interpolation splines by means of an existing R-function? The problem is, that the average value of the computed quarterly values must be the annual value, i.e. the spline should cross the annual values (in a stairs-line plot) in the middle of every annual step.
