R help - Sep 2015 - Error Message when using VarSelection in YaiImpute package with the randomForest

Dear All,

when using the following code

x <- iris[,1:2]  # Sepal.Length Sepal.Width
y <- iris[,3:4]  # Petal.Length Petal.Width
vsel <-
varSelection(x=x,y=y,nboot=5,yaiMethod="randomForest",useParallel=FALSE)


I get the following error code

Error in yai(x = xa, y = y, method = yaiMethod, bootstrap = bootstrap,  :
  object 'xcvRefs' not found


If anybody could tell me what I am doing wrong.

Cheers
Andrew

       useParallel = FALSE)


Any help/guidance would be greatly appreciated.

Kind regards
