Hi, I have a problem while loading the "siar" program in R. When I am loading siar, system does not load convexhull. On the screen I have seen such writings. The following object(s) are masked from ‘package:spatstat’: convexhull How can I load the convexhull, how can I unmask from this package? I will be appreciated if you...

Hello, I recently bought a new Macbook Pro and installed R via a disk image from an older computer - it seems to work fine. I then installed the package "siar", tried to load it via the library command and received the following messages (note the "mvtnorm" package did not appear to load correctly): trying URL 'http://cran.stat.ucla.edu/bin/macosx/leopard/contrib/2.15/siar_4.1.3.tgz' Content type 'application/x-tar' length...

See http://r.789695.n4.nabble.com/Errors-in-SIAR-td4029804.html. In it I note that there are problems with the function from siar (not SIAR) you are using, but that this may not be "your" problem, that the...

I'm absolutely not brilliant with R yet and working with package SIAR. 1) SIAR reads the first column of a table.txt as "int" instead of "num". Who can help? 2) I therefore made tables with a data.frame() > that seems to work. But at the end of the loading proces of the SIARmodel, I get a warning screen with "Session Aborted". Everyth...

Hi, my name is Julio, I'm trying to run a script, specifically with the siar package on R (I have attached the script) but the program collapses on during the run. The error message says: *** caught segfault *** address 0xb31941cc, cause 'memory not mapped' Traceback: 1: .C("siarmcmcv4", as.integer(numdata), as.integer(numsources), as.integer(numiso)...

Hi there, I am trying to run an MCMC on stable isotope data from certain organisms to determine their dietary habits in the package SIAR. I have prepared my data according to Inger, R., Jackson, A., Parnell, A., Bearhop, S. : SIAR V4 (Stable Isotope Analysis in R) an Ecologist's Guide (also better known as 'SIAR for dummies'), which is as follows: - consumer data table (columns include code for species, d15N signature...

Hello, I am trying to run the demoscript for the package "siar". However, using the example script and example data supplied I cannot get 1) the model to run unless I specify iterations =500 and burnin = 500 and 2) if the model does work without crashing R then the function "siarhistograms" does not work . Can anyone point out where I am going...

Saludos: Hace unos días me encontré con un problema en la función readSIAR del paquete solaR; pensé en actualizar pero no lo hice en el momento. El caso es que acabo de actualizar el paquete solaR -y el resto de paquetes también- y veo que el error no se va. ------ Corte desde la consola -------- R version 2.15.1 (2012-06-22) -- "Roasted Marshmallows" Copyri...

...anyone's time, but have been working on this for a couple of days now, think it should have take a few hours! The Problem: Error in Summary.factor(c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 4L, : max not meaningful for factors I have tried to re-arrange and check formula. I am working in SIAR, and cannot get model1 to run because of the error code below. Is this because of the first column being names? How do I rename the columns and to what? Below is the code and data frames with some omissions of values. In the middle is the model I am trying to run, which returns with the error cod...
