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) :

In addition: Warning message:
