Help on multi-line plot
Hello R-Users I am struggling with this line plot, it might be simple but I am missing something here. First of all I want to make multiple line plots across seasons (DJF,MAM,JJA,SON) for 12 variables (here, called nodes) and fill them with the node. So that season=x-axis, node=line col and freq=y-axis. My plot currently links all DJFs, MAMs, JJAs and SONs, however I will like them to be linked across seasons, so that for node 1, I should have a line plot of DJF, MAM,JJA...

Re: [S] scalability
...We know there are overheads in making functions generic, especially BR> S4-generic, but then there are benefits too. I am not sure designers who BR> add features take enough account of the costs. Using R 1.8.1 (precompiled) on SuSe Linux with a Xeon 2.4GHz and 1G of memory: set.seed(2) jja <- array(rnorm(3000*300*3), c(3000, 300, 3)) gc() system.time(jjsa <- apply(jja, 1:2, sum)) # takes 30 seconds sumS3 <- function(x, ...)

Subsetting a zooreg object using window / subset
...data for the 4 years aa<-zooreg(1:1825,start=as.Date("1997-01-01")) My aim is to subset the data according to seasons (Southern Hemisphere) for continuous years: December - January - February (DJF-Summer: 1997-2001), March - April - May (MAM-Autumn: 1997-2001), June - July - August (JJA-Winter: 1997-2001), September - October - November (SON-Spring: 1997-2001) thereby analysing the seasons data only for all years. The example below is only for DJF but I would like to replicate the analysis for each season. My solution so far uses subset to select the monthly data for each year an...

plot filled.contour over continent map
...undaries (e.g. for Europe) What i do is: map('worldHires',xlim=c(-10,40),ylim=c(35,70),boundary = TRUE,border=0.1) map.axes() filled.contour(mslp, zlim=c(1000,1020),color.palette = colorRampPalette(c("blue", "white", "red")),main="Avegared MLSP (hPa) ERA40 JJA [1996-2002]", xlab="Longitude",ylab="Latitude") in which the mslp file is a netcdf file, with mean sea level pressure for a range of lat/lon values. If I run the above-mentioned, I just get the map of Europe, without the contourplot. When commenting the "map" st...
