[R] biglm error:

[Kumar Manglam Thakur]

Trying to implement a simple regression using biglm package for quite some time. But is feeling frustrated with errors. Please suggest any way around for this error.
> formula1 <- IsBadBuy ~ RefId
> for (i in chunk(car, by=1000))
+ {
+ if (i[1]==1)
+ {
+ message("first chunk is: ", i[[1]],":",i[[2]])
+ biglmfit <- bigglm(formula1 , data = car[i,,drop=FALSE])
+ }
+ else
+ {
+ message("next chunk is: ", i[[1]],":",i[[2]])
+ biglmfit <- update(biglmfit, car[i,,drop=FALSE])
+ }
+ }
first chunk is: 1:1000
Error in coef.bigqr(object$qr) :
NA/NaN/Inf in foreign function call (arg 5)
In addition: Warning message:
In Ops.factor(y, mu) : - not meaningful for factors

bigQR$rbar, bigQR$thetab, bigQR$tol, beta = numeric(p), nreq = as.integer(nvar),
ier = integer(1), DUP = FALSE)
10: coef.bigqr(object$qr)

7: coef(iwlm)
