Dear all, this looks pretty much a standard problem, but I couldn't find a satisfying and understandable solution. (A) Given a data frame (or matrix), e.g. x <- data.frame(A=c(1, 2, 2), B=c(4, 5, 5)) and a row of this data frame, e.g. r <- c(2, 5) I need to find one row index i (or all such indices) such that r is at the i-th row in x, that is, the

...kages, so could someone please give me a hint whether there exists a package for fitting exponential curves (of the type t --> \sum_i a_i \exp( - b_i t)) on a noisy signal? In fact monoexponential decay + polynomial growth is what I'd like to try. Thanks in advance, Mirko. -- Dr. M.

Hi there, as part of a 2 x 2 contingency table analysis I would like to estimate conditional probabilities (success rates) in a Bernoulli experiment. In particular I want to test a null hypothesis p <= p0 versus the alternative hypothesis p > p0. As far as I understand the subject, there are UMPU tests for these types of hypotheses. Now I know about R's "binom.test" but the

Any ideas? Thanks, Mirko. -- Dr. M.

Hi folks, I tried to retain the Weibull distribution using the `nls' function and proceeding along the lines of the example provided in the `SSweibull' help (at least I thought so): t <- (1:200)/100 v <- pweibull(t, shape=3, scale=1) df <- data.frame(Time=t, Value=v) Asym <- 1.0; Drop <- 1.0; lrc <- 0; pwr <- 1 df.estimate <- nls(Value ~ SSweibull(Time,

Hi Nidhi, > ... On the other hand, I also found that JRI.jar is missing from > both of these (piodev...) installations. ... this is resolved now in the /mnt/tools/r installation. Background: When compiling R, one needs to provide an option "--enable-R-shlib" in order that R is capable of dynamically linking libraries. Now the desired JRI package (Java calls into R) is part of
