Hello R Users, I am using R on Windows, I am ploting CO2 (350,380) variying with year(1993,2003) I want to over-plot rainfall (10,250) varying with year(1993,2003) on axis-4 axis-1=year(1993,2003), axis-2=CO2(350,380) axis-3=None axis-4=rainfall(10,250) Kindly help how to over-plot another variable on axis-4. Many thanks, Regards, Yogesh [[alternative HTML version deleted]]

Hello 'R' Users, I am very new on 'R', so excuse me if I ask something wrong. I have ASCII data and the colums of the data are looks like :- !------------------------- time,yr,mo,dy,hr,min,sec,lat,lon,ht,co2obs,sigma,co2model -- - -- !---------------------------- Each column has data value. Now I want to produce 2-d color maps, for example the plot should look like :- on

Dear R Users, I have a CO2 time series. I want to fit this series seasonal cycle and trend with fourth harmonic function, and then compute residuals. I am doing something like: file<-read.csv("co2data.csv") names(file) attach(file) fit<-lm(co2~1+time+I(time^2)+sin(2*pi*time)+cos(2*pi*time)+sin(4*pi*time)+cos(4*pi*time)+

Hi, I want 12 ticks at axis 1 and want to write Jan-Dec on each. something like: axis(1, at=1:12, labels=c('J','F','M','A','M','J','J','A','S','O','N','D')) I could omit default ticks but now how to control ticks. plot(file$time, file$ch4*1000, ylim=c(1500,1700), xaxt='n', xlab= NA,

Dear R Users, If we issue simple plot command in R we don't get legend of the plot automatically. For example, following lines plots two curves, but to write a legend of these two curves there is no simple command. I checked with ?legend but it seems bit complicated for me. Does anyone know how to get a legend in a simple way for following R plot. Thanks, Yogesh >plot (x,y,
