Consider this script (with h5 installed):
$ cat test.R
library(h5)
name <- tempfile()
f <- h5file(name)
file.remove(name)
$ Rscript test.R
Error in initialize(value, ...) :
cannot use object of class "character" in new(): class "H5File" does not
extend that class
Calls: h5file -> new -> initia

Thanks for the details. I’m new to R, and I’m not blaming anything here,
just that I’m still not clear what good it makes to keep this inconsistency
between R and Rscript. To me (and probably to many others from Perl/Python
etc.), this is shockingly weird. I can live with that, and I also want to

After a deep dig into the source code, I think I found something worth

The R script I run daily for hours looks like this:
while (!finish) {
Sys.sleep(0.1)
time = as.integer(format(Sys.time(), "%H%M")) # always crash here
if (new.data.timestamp() <= time)
next
# ... do some jobs for about 2 minutes ...
gc()
}
Basically it waits for new da
ormation/updates. If this ends up being a bug in R, please report
