[R] gl1ce warning message?

I am trying to write a function to do Lasso regression on my data:

  for (i in 1:k){
    temp.lasso<-gl1ce(as.formula(paste("y ~ ",paste(colnames(data)[-1],collapse='+'))),

    data=data.frame(data),family=binomial(),bound=i/k)     gcvs[k]<-gcv(temp.lasso)[2]

as I execute my function with some data, I get these messages: Warning messages:
1: `x' and `y' have different environments; x's is used in: merge.formula(formula,

But as I execute commands within this simple function line by line, no warnings are produced. I suspect the data argument should be treated specially but don't know how to. Can anybody give me a solution or hint? Thanks a lot,
