If your data is in data.txt file you can do the following: x <- read.table(file="data.txt",header=TRUE) t<-ISOdatetime(x[,1],x[,2],x[,3],x[,4],x[,5],x[,6]) secs <- as.numeric(t)
So now secs represents your time in seconds and you can use any type of interpolation you wish to interpolate co2obs. --- Yogesh Tiwari <[EMAIL PROTECTED]> wrote: > Hello R Users, > > I am new to R and I have simple problem for R users. > > I have CO2 observations defined on time > axis(yr,mo,day,hr,min,sec).
