Make a list of argsets from every combination of values

expand_list() returns one named list for each combination of the values of its arguments. It works like tidyr::expand_grid(), but it returns a list of lists, which Plan$add_argset_from_list() and Plan$add_analysis_from_list() take.

Usage

expand_list(...)

Arguments

...

Named vectors or lists. Each holds the values of one argument.

Value

A list of named lists, one for each combination. The first argument varies slowest.

Examples

argsets <- plnr::expand_list(location = c("oslo", "bergen"), age = c("0-14", "15+"))
str(argsets)
#> List of 4
#>  $ :List of 2
#>   ..$ location: chr "oslo"
#>   ..$ age     : chr "0-14"
#>  $ :List of 2
#>   ..$ location: chr "oslo"
#>   ..$ age     : chr "15+"
#>  $ :List of 2
#>   ..$ location: chr "bergen"
#>   ..$ age     : chr "0-14"
#>  $ :List of 2
#>   ..$ location: chr "bergen"
#>   ..$ age     : chr "15+"
