Hi, member-list i'm searching for packages or routines to analise fisheries acoustics data. Something make import data of scientific ecosound (EK500) of paralel port, filter signal, analyse pattern of pixel fish shoals... Is there someone work with this ? If no, why dont make colective effort to do this?? (package fish_acoustic). Thanks Marcelo

...,it's size is 500, is composed of x,y and z. The probability of x, y and z is respectively is 0.3, 0.5, 0.2. I wan to simulate a new same size population based ratio of x, y and z, how can I get and assess the number of x, y and z. ? luan Key Laboratory for Sustainable Utilization of Marine Fisheries Resources, Ministry of Agriculture ,Yellow Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, Qingdao 266071,China __________________________________________________ 佈伵伝仮伱佲伔佈G佊伿佅佷仯伃佒佇伖侜伒佢佉伝伨侙佄佫伬伂伝侙佊伿伡侢伾仹伻伵伋伂伌侒佊伿佅佷

Dear Alberto, There are fisheries people also in Europe using AD Model Builder (Denmark and England for instance), but you are probably right that it is more widespread in North America. There is also effort going on where people try to make assessment models written in ADMB callable from R. best regards, hans > think AD Mode...

I have a fisheries Ricker stock-recruitment non-linear model which I am trying to code up in R (after failing in MATLAB). There are two fixed parameters and a random environmental effect that is linked to a first order lagged correlation fixed parameter. Are there any examples of fitting this model I could follow?...

There has recently been some discussion on the list about AD Model builder and the suitability of R for constructing the types of models used in fisheries management. https://stat.ethz.ch/pipermail/r-help/2006-January/086841.html https://stat.ethz.ch/pipermail/r-help/2006-January/086858.html I think that many R users understimate the numerical challenges that some of the typical nonlinear statistical model used in different fields present....

Hi all and thanks in advance. I am regressing Time and Weight, and then predicting Weight at different Time. The format of the Time data is day/month/year. How can I get R to use time series data such as this? Keith -- M. Keith Cox, Ph.D. Alaska NOAA Fisheries, National Marine Fisheries Service Auke Bay Laboratories 17109 Pt. Lena Loop Rd.

For those working in fish stock assessment, we anticipate releasing soon a related group of R functions, FishGraph. The FishGraph functions create graphs useful in analysis of fisheries stock assessments whose output has been saved with X2R. We have been using FishGraph for several years and are now completing the documentation. This work has been tested and used by the authors.

Dear all, I am a new user of R. I would like to know how to get fund's returns in percentage (%). For example, I use: R <- ts(read.xls("FundData"), frequency = 12, start = c(1996, 1)) Whith this program, the returns are like 0.0152699. But, I would like to have 1.52%. Please advise me about the function. Thanks! Fabrice
