Appending objects created using filehash package
...already in the database.
The only way I know now to append to an object, basically requires rewriting
the entire object.
Sample code: =================================================
# Setting up the database
library(filehash)
A <- data.frame(a=c("abcde", "fghij", "klmno"), stringsAsFactors=FALSE)
dumpDF( A, dbName="myTestDB")
envTest <- db2env(db="myTestDB")
ls(envTest)
with(envTest, a)
# Appending to object a, but basically rewriting it...
envTest$a <- c(envTest$a, "HELLO", "GOODBYE")
with(envTest, a)
If anyon...
