Dear R-help, In my Master thesis I measured 10 variables from 18 lakes. These measurements were taken 4 times a year in 3 depths, so I have 12 samples from each lake. I know that 12 samples can not be treated as replications, since they don't correspond to the same environmental characteristics an

Re: [R] Saving objects inside a list

Hello, (and a happy new year for you too!) Apparently the problem is happening only within my RKWard sessions: > B = 1000 > oblist = as.list(.GlobalEnv) > str(oblist) List of 1 $ B:function (value) > oblist$B function (value) { if (!missing(value)) { assign(k, value, envir = .rk.watch

Re: [R] how to keep keep matching column in output of merge

Hi Nevil, We really need an example here of what you're doing, since merge() does keep the id column by default. > x <- data.frame(id = c("a", "b", "c", "d"), x=c(1,2,3,4)) > y <- data.frame(id = c("b", "a", "d", "c"), y=c(101, 102, 103, 104)) > merge(x, y) id x y 1 a 1 102 2 b 2 101 3 c

Re: [R] lasso/lars error

I'm having the same error too, but it's very rare though... (especially when using datasets with many variables, say 25). A somewhat odd, but seemingly effective, way to solve this, is by writing try(lars(x,y),silent = T). The try-command in this shape will not generate an error on the console and

Re: [R] lattice: par.settings with standard.theme() + additional arguments?

Dear David, this I already tried. But as you can see, the plot itself *is* colored. However, I want to have color = FALSE, so, unfortunately, this approach does not work... Cheers, Marius On 2011-01-04, at 14:32 , David Winsemius wrote: > > On Jan 4, 2011, at 5:57 AM, Marius Hofert wrote:

Re: [R] how to subset unique factor combinations from a data frame.

Hi: Did you try something like summdf <- as.data.frame(with(df, table(Commodity, Attribute, Unit))) ? The rows of the table should represent the unique combinations of the three variables Here's a simple toy example to illustrate: > x <- sample(LETTERS[1:6], 1000, replace = TRUE) > xx <- sa

Re: [R] ARIMA simulation including a constant

That output is not from arima(), which is the function paired with arima.sim(). Nor is it from arima0(), so I don't believe it is 'ouptut from R' (perhaps from a contributed package you have not mentioned?). With arima(), the intercept is 'm' in the notation on the help page and not 'a' in y
