Error in eval(expr, envir, enclos) in getMarket from package betfair

Question

I'm having some problems with the getMarket function from package betfair. Here's the gist of it:

g <- function(x){
    getMarket(x)
}
g(110501389)

This throws:

Error in eval(expr, envir, enclos) : object 'x' not found

g is in the global environment, and getMarket is from namespace:betfair.

I've never had this problem with other packages (e.g., mlogit). Any ideas?

traceback() gives:

10: eval(expr, envir, enclos)
9: eval(parameters[[j]])
8: FUN(1:2[[1L]], ...)
7: lapply(1:length(parameters), function(j) { ...
6: paste(lapply(1:length(parameters), function(j) { ...
5: .list2xml(parameters, allowNull)
4: paste(body, .list2xml(parameters, allowNull), sep = "")
3: .bfapi(match.call(), service = service)
2: getMarket(y) at .active-rstudio-document#2
1: g(110501389)

Answer 1

It is a bug in betfair::getMarket() in the first line: .bfapi(match.call(), service = service)

match.call() when called from g() gives: getMarket(marketId = x) But x is not defined in getMarket().

To illustrate this, try this wrapper:

 h <- function(marketId){
   getMarket(marketId)
 }
 h(110501389)
