iteratelist function

Create an iteration list from a R object

In some case it is useful to iterate over a named list or vector

iteratelist will create a new unnamed list with name value members: each item will be a list where 'name' is the corresponding name and 'value' is the original value in list x.

iteratelist(x, name = "name", value = "value")

Arguments

• x: list or other object that will be coerced to list
• name: character name for resulting name member.
• value: character name for resulting value member.

Returns

unnamed list with name value lists

Examples

# create an iteration list from a named vector
x <- c(a=1, b=2)
iteratelist(x)

# iterate over the members of a list
x <- list(name="John", age="30", gender="male")
iteratelist(x, name="variable") 

# iterate over an unnamed vector
values <- c(1,2,3,4)

template <- 
'{{#values}}
* Value: {{.}}
{{/values}}'

whisker.render(template)

#or 

values <- iteratelist(values, value="count")

template <- 
'{{#values}}
* Value: {{count}}
{{/values}}'

whisker.render(template)
