Hi everyone, I am using the MCmcmc function of the MethComp package and receive the following error:
Error: 'coda.samples' is not an exported object from 'namespace:coda' I emailed the package author last week but haven't had a reply. I have installed JAGS 3.4.0 as required by MethComp. I am using R 3.1.2 and the MethComp currently on CRAN (1.22.1). I am not a regular R user so haven't had any luck making sense of the error, though there are references to namespace in the package check results here: http://cran.itam.mx/web/checks/check_results_bxc_at_steno.dk.html#MethComp. Not sure if that's relevant. Any suggestions would be appreciated. Apologies if I haven't provided any required information. The following shows my code and error (code taken from the package author's text 'Comparing Clinical Measurement Methods', Bendix Carstensen, section 7.5.3) : >library(MethComp) >data(ox) >ox<- Meth(ox) >m3<- MCmcmc(ox, IxR=TRUE, n.iter=50000) Comparison of 2 methods, using 354 measurements on 61 items, with up to 3 replicate measurements, (replicate values are in the set: 1 2 3 ) ( 2 * 61 * 3 = 366 ): No. items with measurements on each method: #Replicates Method 1 2 3 #Items #Obs: 354 Values: min med max CO 1 4 56 61 177 22.2 78.6 93.5 pulse 1 4 56 61 177 24.0 75.0 94.0 Simulation run of a model with - method by item and item by replicate interaction: - using 4 chains run for 50000 iterations (of which 25000 are burn-in), - monitoring every 25 values of the chain: - giving a posterior sample of 4000 observations.
