Dear All, Help is needed! I have a matrix with frequencies of fish larvae per length class (var. sl) and age-group (var. median.no) obtained with >k<-table(cut(sl,(5:22)),median.no) >k[2:5,1:5] #to ilustrate k 4 5 6 7 (6,7] 3 1 0 0 (7,8] 3 0 1 0 (8,9] 3 4 3 5 (9,10] 3 15 7 13 from this matrix I would like to obtain the mean age per length class i.e.

Dear All, I'me having (much) trouble understanding why it happened and answering a referee's comment to part of a submitted manuscript. I've tried to google for help but... I'm really confident that although this is a R-Help list someone can help me! I used R to do an ANCOVA w/ RNA/DNA as the dep var, sl as the indep var and gut (a factor w/ levels: prey and empty) as the

Dear All, I'm a Marine Biologist using R (in a most informal and applied way) for a couple of years. Actually, I've been using R to analyse the results supporting my thesis. I would like to put together (in the same file) the data (.txt files) and the scripts files (.R files) for each chapter. How can I do this? Thanks in advance, Eduardo Esteves [[alternative HTML version deleted]]

Dear All, I'd like to fit a "kind" of logistic model to small data-set using nonlinear least-squares regression. A transcript of R-script are reproduced below. Estimated B and T (the model's coeff, herein B=-8,50 and T=5,46) seem appropriate (at least visually) but are quite diff from those obtained w/ SPSS (Levenberg-Marquardt): B=-19,56 and T=2,37. Am I doing something wrong in

Dear All, I'm trying to calculate the following: g.rate<-(SL-int)/NO where SL and NO are individual length and counts for the same subject, and the int value is a day-specific value i.e. for each DAY=88, 101..., 172 I'd like to use a different values of int=9.32, 8.43, ..., 9.81. All variables are compiled in a larger data.frame of the form: CODE SL NO DAY (...) 123 12.5 14

Dear All, I'm having trouble tweaking a forest plot made using the R meta-analysis package metafor. I did the analysis based upon the correlation coeff from studies and plotted the corresponding forest plot easily > q2<-rma(yi,vi,mods=cbind(grupo),data=qim) > q2 > forest (q2,transf=transf.ztor,digits=3, ... ,alim=c(0,1),refline=.5) > text(-1.55,42,"Esp?cie

Is there anyone insterested in taking an online course which covers "Ruby on Rails" (introductory level)? Thanks thuycis -- Posted via http://www.ruby-forum.com/.

*Thanks* all those who took the time to help me (even if the "question" was not related to - the use of - R). Now I think I can soundly make my point w/ the referee (can I use your replies? If so I intend to properly cite its use?!?). Regards, Eduardo Esteves ps - Sorry for not explaining the "biological details" of my posting: RNA/DNA is the ratio of RNA content to

Hi, I'm mainly insterested on the x86 JIT compiler. /lib/Target/X86/README.txt talks about 'Jello', the JIT compiler, which should be on /tools/jello. I think that changed to /tools/lli and now comprises a bytecode interpreter as well. Is that right? -- Oscar

I'm trying to plot a ibm stock time series. I made the download of that series, ibm <- get.hist.quote(instrument = "ibm", start = "2003-01-01",quote=c("CL")) And ibm is a serie wiht this characteristic: Start = 37623 End = 37960 Frequency = 1 When I try to plot it, ts.plot(ibm) In the graphic the axe time is represented by 37623 ... 37960, How can I put

Hello- This goes for all those insterested in contributing with the effort to have better Debian documentation, and are willing to submit material to the Science section of the DURG, in order to divulge R to a wider public. Please write directly to the author of the Science: Andreas Franzen <anfra at debian.org> Regards, Henry L.

Hi all, I'm using the quantreg package to run some regressions. I'm trying to save the output as latex tables using the helpful "latex" command, which works fine. However, I've been unable to modify its behavior in some ways I'm insterested in. For instance, I'd like a table in which I had the asterisks corresponding to the significance levels of each variable, but I

Hello, I have a matrix with values, with columns c1..cn. I need the values to be normalized between 0 and 1 by column. Therefor, the 0 should correspond to the minimum value in the column c1 and 1 should correspond to the maximum value in the column c1. The remaining columns should be organized in the same way. Does a function in R exists for this purpose? Thanks, Rui [[alternative HTML

I am trying to create a classification tree using either tree or rpart functions but when it comes to plotting the results the formatting I get is different than what I see in all the tutorials (like http://www.youtube.com/watch?v=9XNhqO1bu0A or http://www.youtube.com/watch?v=m3mLNpeke0I&feature=related or http://www.statmethods.net/advstats/cart.html "tree for kyphosis").

Dear All, I'm confortable with xyplot(...) and panel.lmline(...) statements (at least I thought I did :). I've used the following code to plot the decline in log-abundance of fish larvae (no.larvae) with age (age.cls, 4 to 27 days-old) for specific dates of sampling (day, 9 dates). I further plotted data with different colors and regression lines for ages 5-14 d and 17-23 d in a 7-by-1
