Similar to Bill, I also have an inelegant, but workable, solution, which is

to brute force the ignore times by templating them in R.

For example, you can use a simple glue template to churn out ignore

statements. For simplicity this could then be then just copied into control

streams.

library(whisker)

all_times <- c(0, 1, 2, 4, 6, 8, 10, 12, 14, 16, 20, 24)keep_times <-

c(0, 1, 2, 4, 6, 24)drop_times <- all_times[!(all_times %in%

keep_times)]glue::glue(

"IGNORE=(TIME.EQN.{time})", time = drop_times

)#> IGNORE=(TIME.EQN.8)#> IGNORE=(TIME.EQN.10)#>

IGNORE=(TIME.EQN.12)#> IGNORE=(TIME.EQN.14)#> IGNORE=(TIME.EQN.16)#>

IGNORE=(TIME.EQN.20)

# make multiple time scenarios and generate the ignores for all of

them in one goscenarios = list(

c(0, 1, 2, 4, 6, 24),

c(0, 2, 4, 8, 24))

lapply(scenarios, function(.s) {

all_times <- c(0, 1, 2, 4, 6, 8, 10, 12, 14, 16, 20, 24)

keep_times <- .s

drop_times <- all_times[!(all_times %in% keep_times)]

glue::glue(

"IGNORE=(TIME.EQN.{time})", time = drop_times

)})#> [[1]]#> IGNORE=(TIME.EQN.8)#> IGNORE=(TIME.EQN.10)#>

IGNORE=(TIME.EQN.12)#> IGNORE=(TIME.EQN.14)#> IGNORE=(TIME.EQN.16)#>

IGNORE=(TIME.EQN.20)#> #> [[2]]#> IGNORE=(TIME.EQN.1)#>

IGNORE=(TIME.EQN.6)#> IGNORE=(TIME.EQN.10)#> IGNORE=(TIME.EQN.12)#>

IGNORE=(TIME.EQN.14)#> IGNORE=(TIME.EQN.16)#> IGNORE=(TIME.EQN.20)

If you want something more automated and powerful, at the expense of more R

code, you can use the whisker library to actually use full templates. I've

done some bayesian prior sensitivity analysis generating 1000's of control

streams to great success that way. If this is of interest, speak up and I

can provide a more complete example.

Cheers,
