[R] Simple spectral analysis

the periodogram (and the residuals from the reassembled data set...) Thanks and greetings, Georg The data set: air = read.csv(http://www.hydrology.uni-kiel.de/~schorsch/air_temp.csv;) airtemp = ts(T_air, start=c(1989,1), freq = 365) plot(airtemp) -- Georg Hoermann, Dep. of Hydrology, Ecology

in R compared to other packages 8-) Thanks a lot for the help. I will post the script when its ready (an introduction for our biology students to time series, just 8 hours) Georg -- Georg Hoermann, Dep. of Hydrology, Ecology, Kiel University, Germany +49/431/23761412, mo: +49/171/4995884, icq

[R] Strange Colnames

Hello world, I am trying to create a matrix of lagged time series with the following code fragment (I know that I can use acf-function...). I want to set the variable/column name to something like lag 1 etc. If I try to do it I get text like lagtest.lagtest.lagtest.lag 1 where does this come from?

Re: [R] Strange Colnames

the lag from the default value of 1 to -1, but I apparently missed something: do.call(cbind, lapply(lags, function(x) lag(x,-1), x = lagtest)) Error in FUN(X[[1]], ...) : unused argument(s) ( ...) where is the unused argument? Thanks, Georg -- Georg Hoermann, Dep. of Hydrology, Ecology, Kiel
