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.
