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

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...

Problem converting zoo object (daily data) to a timeSeries object
...a zoo object with the intention of
converting it into a timeSeries.
My apologies if this is too basic a question, but I am new to R and have
been struggling with this problem.
The object in question contains daily adjusting closing price data.

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...
