Dear group, First I provide you with an example, I found in the newsgroup. Then I'd like to explain my problem to you by means of the output. enviro <- data.frame(Year = rep(2001:2002, each = 365), Day = rep(1:365, 2), Precip = pmax(0, rnorm(365 * 2)), Temp = 2 + 0.2 * rnorm(365 * 2)) xyplot(Precip + Temp ~ Day | Year,

Hi all, I have a question concerning xyplot. My data is a data.frame looking like that: In the first column I have numbers from 0 to 23 (hours of a day), the second column contains the name of a weekday (Day as factor) and the third column contains the number I am interested in. So as an example, the first five rows look like that: Hour Day Freq 1 0 Mo 23 2 1 Mo

Hello everyone, does somebody know how can I save an object list as a txt-file or as a csv-file? The problem is, that the elements of this list have different row length. So I cannot convert the list into a matrix or something else and then use "write-matrix" or so as usual. Thank you very much for your help. Regards, Antje [[alternative HTML version deleted]]
