...lt;- sum(!obs & model) s1/(s1 + s2 + s3) } modeldepths <- lapply(modeldepths, function(x) f2(observeddepth, x)) modeldepthnew <- modeldepth[modeldepth > 0.7] # Here the objective is to pick the 31 of the 54 files (31 of the 54 elements have an f2 greater than 0.7) with their complete 272x976 cells because that information will then be used in the next step. The next step will be to perform a Bayesian inference where the modeldepthnew represents the prior likelihood. Are there any suggestions on a specific R package to use in the Bayesian inference steps? Thank-you. Irucka Embry...
