.Random.seed(0) is not a valid Normal type
Dear R-Developers and -Community, after compiling and installing R 1.2.2., I started 'demo(graphics)' for a test, and got: 'Error in rnorm(0): .Random.seed(0) is not a Normal type' Obviously .Random.seed was not initialized appropriately. Following the the documentation for '.Random.seed' [see below 'Examples'], this can be fixed rm(.Random.seed);

stochastic growth rate (package biopop)
Dear all, I am running matrix population models using package "popbio". In a deterministic model {i.e., transition matrix is defined as A <- matrix(c(0.70, 0.70,0.35,0.50), nrow=2,byrow=TRUE}, population growth rate can be estimated from the dominant eigenvalue {command "eigen.analysis"}. However, I cannot figure out the way to compute the asymptotic stochastic population

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,

unable to install package ff
Hi all, I've had one of my most miserable R weeks in memory. I'm trying to deal with huge datasets (>1GB each) but am running up against those pesky memory limits. The libraries filehash and g.data are not very suitable for what I need. I haven't gotten into the sql thing yet. Most recently I've been trying to install the new package ff (not yet on the CRAN repository). I

Stick on installation: winecfg not found
Hi, I followed the installation instruction step by step with the wine 1.3.13 package. I stick at point 3.1 user guide: using winecfg.

There is a directory winecfg under wine-1.3.13/programs/ but no executable files. The wine package is installed under

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

After Update to 4.2, Samba is unusuable as member server / No user and goup resolution
Hello everybody, I've bin running Samba as a AD member server for ages (Debian stable). After the last update to 4.2, I just can't get it to work. Symptoms: unable to map AD user / groups. After two days of successlessly fiddling (and moving all data to another server with still Samba 3.6, which I will definitely NOT update at the moment), I decided to purge my Installation and start

stepfuns: R^2 -> R
Does anyone have any suggestions on perspective plotting of piecewise constant functions? Ideally, I would like something like plot.stepfun for functions that are piecewise constant on polygons. Even pointers to non-R strategies would be welcome at this stage. url: www.econ.uiuc.edu Roger Koenker Dept. of Economics UCL, email rkoenker at uiuc.edu Department of Economics Drayton House, vox:

Extending a data frame
Dear all, all data I am talking about can be found at <http://www.metaanalyse.de/tmp/test.dat>. The R-code is located at <http://www.metaanalyse.de/tmp/test.R> I'd like to plot the frequencies for status against year. Typing table(tmp$year) it can be simple seen that some years are missing, e.g. 1975-1978, 1981 etc. Using xyplot to display the data I do not like the fact

help on barplot
Hello, I am trying to compare two histograms using barplot. the idea is to plot the histograms as pairs of columns side by side for each x value. I was able to do it using barplot before but I can't remember now for the life of me now how I did it in the past: > d [,1] [,2] -37.5 0.0000000000 2.789396e-05 -32.5 0.0001394700 5.578801e-05 -27.5 0.0019804742

Hello. I'm writting a glx device and I've some performance problem with the eventloop registration system. The device is not refresh when there's no X event. That's problematic for animation and "smoothness" of display. Should I use threads or fork the R process to get and independant way to refresh my device ? Or do you know another way to refresh it ?

Installing rgl in R2.0.1
I'm running R2.0.1 under Solaris 2.9 on a SunBlade 100. When I installed it, I set things up to use the Sun compilers cc, CC, f95 with the options recommended in the installation and administration guide. Until today, no worries. With all this discussion about R GUIs I thought I'd give R Commander a go. The web page said to install a bunch of packages first, so I did >

How to do a trig regression
Hello All, I cant seem to do a trig regression in R. The equation is as follows : y = a+b*(sin((2*pi*x/360) - c))^2 a, b, c are coefs that I want. y, x are input vectors. The equation I put into R: lm(y ~ sin(2*pi*x/360)^2) This equation is missing the c and I dont get the right answer. Also, I dont know how to plot the lm over the x values instead of the indices. Any help is sincerely
