How to load precomputed data

[vasishth]

Can I do this in a markup file? I.e., I store the precomputed Stan analysis results in the data directory (it takes a long time to compute).

if (file.exists("../../data/KB07_stan.Rda")) {
load("../../data/kb07_stan.rda")
} else {

run stan model:

kb07model <- stan("KB07model.stan",
data = dat,
chains = 0)

I wouldn't use explicit paths like that. There is an R function to access the directory in which a package is installed but I have forgotten its name and can't seem to find it. I know it is Pkg.dir() in Julia but that doesn't help here.

The function I was thinking of is system.file() with the optional package= argument.
