I did not follow your example, neither do I use the deSolve package; but
why not pass an environment as an argument?
## some iterative function that takes another fun as argument
outer <- function(fun, ...) {
for (i in 1:20)
fun(...)
}
## create an environment ...
info <- new.env()
info$tt <- 0
## ... and pass it as an argument
myfun <-function(e) {
e$tt <- e$tt + 1
cat("Iteration ", e$tt, "\n")
}
outer(myfun, info)
info$tt
Sounds like a good idea. Tried it. Got exactly the same phenomenon as
with my idea. The "tdone" variable stays equal to 0 and there is no
progress report (as desired) until time gets up to 0.1. Then tdone gets
re-set to the value of tt *every* call, so that tt - tdone is always
equal to 0 and there are no further progress reports.
I have attached a tar-ball and a zip archive both containing the
necessary code to demonstrate the forgoing. Unpack, source all the *.R
files and then source "demoScript" to see it happen before your very
eyes. :-)
