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

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 Model Builder is mainly used for fisheries assessment in North

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

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.

We announce the availability of three related software libraries: C2R, ADMB2R, and For2R (together, X2R). Each contains output routines to simplify transfer of complicated data structures from models written in a compiled language to R. The user's data can be written as a structured ASCII file which, when read by R (note 1) with a single dget() function call, will become an R data object

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

I am trying to great a new column of effort data from an existing vector of gears used. It is a simple code where effort[Gear==300]=(DIST_TOW*7412) effort[Gear==301]=(DIST_TOW*7412) The code appears to work for some of the data but fails for others and inserts a NA value I also get this warning message Warning message: number of items to replace is not a multiple of replacement length Can

I have re-labeled tick marks on the x axis. The problem is that by using axes=FALSE, the axes disappears and when they are called back using axis(side=1)..etc. the axis on sides 1 and 2 do not meet at the bottom left corner of the graph. I would also like to have the 3rd and 4th axes in there as well, all meeting in their respective corners. par(mfrow=c(1,2)) gut<-c("Full",
