Hi, since bigglm doesn't have update, I was wondering how to achieve
something like (similar to the example in ff package manual using biglm):

 first <- TRUE
 ffrowapply ({
  if (first) {
   first <- FALSE
   fit <- bigglm(eqn, as.data.frame(bigdata[i1:i2,,drop=FALSE]), chunksize =
10000, family = binomial())
  } else {
   fit <- update(fit, as.data.frame(bigdata[i1:i2,,drop=FALSE]), chunksize =
10000, family = binomial())
  }
 }, X=bigdata, VERBOSE = TRUE, BATCHSIZE = nmax)

Many thanks.
