filehash - multiple indices via '[' not allowed when using RDS format
...r, recently I found filehash gives an error when I need to do
something like db[c("a", "b")] when the db is in RDS format. Does any one
know a way to get around that?
The code below reproduces the error
thanks
Jeff
filehashOption(defaultType = "DB1")
dbCreate("mydb3", type = "DB1")
db = dbInit("mydb3")
db$a = rnorm(100, 1)
db$b = rnorm(100, 1)
with(db, c(a = mean(a), b = mean(b)))
sapply(db[c("a", "b")], mean) # works.
filehashOption(defaultType = "RDS")
dbCreate("mydb4", type = "RDS"...
