Hi all,
I am having trouble loading a ff object previously saved in a different
computer. I have both files .ffData and .RData, and the first of them is
13Mb large from which I know the data is therein. But when I try to ffload
it,
checkdir error: cannot create /home/_myUser_

see ?merge,
for your dataframes, the following should work:
merge(bat_activity, weather, by=c(date, time), all=T)

first problem: the "blank" space in first position in the first line. Try
removing it, so that the file looks like this:
"1","2","3","4"
"1",484,43,67,54

to see the limitations, but I hope it helps.
a foo example:
myArr <- ff(NA, dim=rep(904,3), filename="arr.ffd", vmode="double")
myMat <- matrix(1:904^2, ncol=904)
for ( i in 1:904 ) {
myArr[,,i] <- myMat
}
Thanks all,

Hi all,
I am trying to fill a 904x904x904 array, but at some point of the loop R

packages such as "bigmemory", but I need help to decide which is the best
way to store such an object. It would be perfect to store it in thi
