Subject: Problem to read file with filehash
Dear R users,
I try to use a very large file (~3 Gib) with the *filehash* package. The
length of the dataset is around 4,000,000 obs. I get this message from R
while trying to "load" the dataset (named "cc084.csv"):
I launched the following codes:
library(*filehash*)
dumpDF(read.csv("cc084.csv", header=T), dbName="db01")
mydb <- db2env("db01")
R replied:
> dumpDF(read.csv("cc084.csv", header=T), dbName="db01")
Erreur : impossible d'allouer un vecteur de taille 15.6 Mo (French)
Error: impossible to allow a vector of size 15.6 Meg (my English
translation)
There must be something I'm doing wrong... I would appreciate any help.
Thank you.
My R version is 2.8.1.
Rock
