Running traceback() I get the following

> traceback()
10: yai(x = xa, y = y, method = yaiMethod, bootstrap = bootstrap,
        ...)
9: withCallingHandlers(expr, warning = function(w)

8: suppressWarnings(yai(x = xa, y = y, method = yaiMethod, bootstrap =
bootstrap,
       ...))
7: grmsd(one = suppressWarnings(yai(x = xa, y = y, method = yaiMethod,
       bootstrap = bootstrap, ...)), ancillaryData = y, wts = wts)

5: suppressWarnings(grmsd(one = suppressWarnings(yai(x = xa, y = y,

       wts = wts))
4: FUN(1:5[[1L]], ...)
3: myapply(1:max(1, nboot), function(i, xa, y, wts, yaiMethod, bootstrap,
       ...) suppressWarnings(grmsd(one = suppressWarnings(yai(x = xa,
       y = y, method = yaiMethod, bootstrap = bootstrap, ...)),
       ancillaryData = y, wts = wts)), xa, y, wts, yaiMethod, bootstrap,
       ...)
2: unlist(myapply(1:max(1, nboot), function(i, xa, y, wts, yaiMethod,
       bootstrap, ...) suppressWarnings(grmsd(one = suppressWarnings(yai(x
= xa,
       y = y, method = yaiMethod, bootstrap = bootstrap, ...)),
       ancillaryData = y, wts = wts)), xa, y, wts, yaiMethod, bootstrap,
       ...))
1: varSelection(x = x, y = y, nboot = 5, yaiMethod = "randomForest",
       useParallel = FALSE)


Any help/guidance would be greatly appreciated.

Kind regards
Andrew

Subject: Error Message when using VarSelection in YaiImpute package with
the randomForest
To: r-help at r-project.org


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
