Hello everybody!


I am writing to consult you a problem that I have to run the SIAR
model, previously
I had Windows 7 operating system and the model ran without any problems, but
recently changed my computer and it’s operating system is Windows 8, now I have
run the model using my original files that previously ran without problem
but whenever the Rstudio sends me this error message:

> setwd("D:/R/vaquita_2")

> sources <- read.table("sourcesdemo.txt",header=TRUE)

> consumers <- read.table("geese1demo.txt",header=TRUE)

> corrections <- read.table("correctionsdemo_RC.txt",header=TRUE)

> concs <- 0 # use this line if you dont want to run with concentration
dependence

> model1 <- siarmcmcdirichletv4(consumers, sources, corrections, concs)

Error in siarmcmcdirichletv4(consumers, sources, corrections, concs) :

  (list) object cannot be coerced to type 'double'

I have installed the R program twice, but I can’t run the model as before,

I really appreciate all the help you can give me on this problem



Best regards!!



Mónica
