matrix creation
Hello, I am trying to create multiple matrices (to run a PVA) but can't import all of them from a .csv without the numbers treated as labels and not factors. I can enter the matrix slowly: Site05_96 <- matrix(c(0.07,0,0.03,0.00,NA,0.00, 0.09,0.166666667,0.31,0.42,NA,0.00, 0.00,0,0.00,0.00,NA,0.00, 0.00,0,0.00,0.00,NA,0.00,

popbio and stochastic lambda calculation
Hello R users, I am trying to calculate the stochastic lambda for a published matrix population model using the popbio package. Unfortunately, I have been unable to match the published results. Can anyone tell me whether this is due to slightly different methods being used, or have I gone wrong somewhere in my code? Could the answer be as simple as comparing deterministic lambdas to

Elasticity in Leslie Matrix
Dear R-users, I would like to calculate elasticities and sensitivities of each parameters involved in the following transition matrix: A <- matrix(c( sigma*s0*f1, sigma*s0*f2, s, v ), nrow=2, byrow=TRUE,dimnames=list(stage,stage)) The command "eigen.analysis" avaliable in package "popbio" provides sensibility matrix and elasticity matrix

contour algorithm
First time user, so sorry if I don't understand protocol.. Anyway, I have created a data frame consisting of pearson's R values at various x and y coordinates and then plotted this using filled.contour. My data is similar to fMRI data except that it is a surface map reconstructed from histological sections. I like the results but would like to know how contours were detected. Google search

Re: Need help on how to list functions from a loaded package...
To All How does one get a list of functions from a loaded package so that one can then get the appropriate help for each of the functions. Currently my method is based on a lot of trial-and-error. Here's an example of what I mean... >From this forum I learn that an interesting package called "multtest" exists on Bioconductor. I then use R Console's "Packages" --

eigenvalues of matrices of partial derivatives with ryacas

I have the following equations in ryacas notation: > library(Ryacas) > FIh <- Expr("betah*Sh*Iv") > FIv <- Expr("betav*Sv*Ih") > VIh <- Expr("(muh + gamma)*Ih") > VIv <- Expr("muv*Iv") I

faster GLS code
Dear helpers, I wrote a code which estimates a multi-equation model with generalized least squares (GLS). I can use GLS because I know the covariance matrix of the residuals a priori. However, it is a bit slow and I wonder if anybody would be able to point out a way to make it faster (it is part of a bigger code and needs to run several times). Any suggestion would be greatly appreciated. Carlo

Popbio - can't find or load
Hello, I'm in need of running a PVA and want to load {popbio}. However, I can't find it. I can't see where or how to load it. I have added repositories and changed the CRAN mirror site. I see {polynom} and {popgen} but no {popbio} between. What am I doing wrong? Thanks, Michelle [[alternative HTML version deleted]]

Find last row (observation) for each combination of variables
Let's say I have a data.frame like A B C TS other columns 1 1 1 12345 1 1 1 56789 1 2 1 23456 1 2 2 23457 2 4 7 23458 2 4 7 34567 2 4 7 45678 and I want the last row for each unique combination of A/B/C, where by "last" I mean greatest TS. A B C TS other columns 1 1 1 56789 1 2 1 23456 1 2 2 23457 2 4 7 45678 I did this simply in SAS: proc sort data=DF; by A B C descending TS

using popbio, reduce number of digits in image2 plot
Hello All. I am using the image2 plot function in the popbio package to create 6 elasticity analyses. I am trying to reduce the number of significant digits that displays -- from 3 digits to 2. I tried rounding my original matrices, but one is comprised primarily of zeros, and the cut / breaks options returns an error message. (see code and error message below) Here are the elasticity values

How to create a legend that automatically reads the values from two vectors?
Hi all!!! How can I create a legend to my plot that automatically reads the values from two vectors? betav<-c(0.78,0.94,0.88,0.41,0.59,4.68) etav<-c(235.6,59.5,31.2,8.7,3.2,1174) I want my legend to show 6 lines beta(in greeks)=0.78,eta(in greeks)=235.6 beta(in greeks)=0.94,eta(in greeks)=6.59 .... beta(in greeks)=4.68,eta(in greeks)=1174 I know how to do it "by hand" but I have

Modify the plot from countCDFxt
Hello, I am running the plot from countCDFxt (popbio). I would like to report the y-axis as a percent instead of the log scale (e^01...). I can add an axis with axis(2, 0:1, line =2) but I'm having trouble understanding how to assign the tic marks (with 'at ='). I'd like to tell it to make tics with the percent value (or decimal if that's my only option) at the equivalent of
