similar to: filehash - multiple indices via '[' not allowed when using RDS format

Hello, I'm using filehash on the windows XP and it has been working fine with the newest R version 2.6.2. However, on the windows vista, when I ran the same code, I got the following error: > dbCreate("simdb") #create simdb database [1] TRUE > db<-dbInit("simdb") #initiate an object of database Error in sprintf(gettext(fmt, domain = domain), ...) : object

Trying to install package 'filehash' I get the following error on FreeBSD 9.0-CURRENT (amd64) with R version 2.11.0 (2010-01-15 r50990): ----------------------------------- R CMD INSTALL filehash_2.0-1.tar.gz * installing to library '/usr/local/lib/R/library' * installing *source* package 'filehash' ... ** libs gcc -std=gnu99 -I/usr/local/lib/R/include

Hi (Roger), I saw the announcement of filehash v2.0 and the sentence "This development has lead to better file locking for concurrent access and faster reading and writing of data in general" caught my attention. What kind of file locking do you refer to here? I am looking for a mechanism that can be used to lock files for reading and/or writing, and I'd love to have a cross

I have just uploaded to CRAN version 2.0 of the 'filehash' package. This version contains a major rewriting of many of the internals (much rewritten in C) for the DB1 format, which is the default. This development has lead to better file locking for concurrent access and faster reading and writing of data in general. In addition to rewriting the internals, I have added two modules for a

Hi all, I am trying to use the filehash library to analyze a 5M by 20 matrix with both double and string data types. After consulting a few tutorials online, it seems as though one needs to first read the data into R; then create an R object; and then assign that object a location in my computer via filehash. It seems like the benefit of this is minimizing memory allocation when running

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"): > dumpDF(read.csv("cc084.csv", header=T), dbName="db01") Erreur : impossible d'allouer un vecteur de taille 15.6 Mo (French) Error:

Hi, I am working with a very large dataset, and am using the 'filehash' package to manage such a large file. While I have no problem accessing objects that I load into a database, I was hoping there is a better way to append to objects already in the database. The only way I know now to append to an object, basically requires rewriting the entire object. Sample code:

Dear R-list I'm on my way to start a new project on a rather big panel, consisting of approximately 8 million observations in 30 waves of data and about 15 variables. I have a similar data set that is approximately 7 gigabytes in size. Until now I have done my data management in SAS, and Stata, mostly identifying spells, counting events in intervals, and a like, but I would like to

Dear R helpers: I am a newbie to R and have a question related to cleaning large data frames in R. So far, I have been using SAS for data cleaning because my data sets are relatively large (handling multiple files, each could be as large as 5-10 G). I am not a fan of SAS at all and am eager to move data cleaning tasks into R completely. Seems to me, there are 3 options. Using SQL, ff or

Dear R'ers, I have trouble installing tikzDevice in Ubuntu.  When I use install.packages("tikzDevice"), it gives error message: ERROR: dependency ‘filehash’ is not available for package ‘tikzDevice’ * removing ‘/usr/local/lib/R/site-library/tikzDevice’ Then I tried filehash installation, I get the message: "package ‘filehash’ is not available (for R version 2.13.1)"

Hi, I am trying to build a binary of Rquantlib package 0.3.5 under Window 7 64bits. I am using mingw gcc version 4.5.1 (tdm64-1) which is a experimental version of 64 bits ming gcc. (http://tdm-gcc.tdragon.net/). I have successfully compiled boost 1.45 and Quantlib 1.0.1 with this gcc. And then when I tried to compile Rquantlib 0.3.5, it reports some error. The first error is like below.

Hello, I have just installed v 2.6.2 on a new computer running Windows XP and tried to perform 'update packages' via the menu option on the R console.

Has anyone tried to (recently) install asterisk in a location not relative to /, as a non-root user? Ie editting the PREFIX directive in Makefile. Why? Several quite obvious reasons: a). Allows an asterisk user to be created, and operators to log into the box as asterisk user, without having root access. b). Much easier backups, because everything is beneath the same directory structure. c).

Hi all, several packages print messages during loading. How do I avoid to see them when the packages are in the defaultPackages? Here is an example. With this in ~/.Rprofile ,----[ ~/.Rprofile ] | old <- getOption("defaultPackages") | options(defaultPackages = c(old, "filehash")) | rm(old) `---- I get as last line when starting R: ,---- | filehash: Simple key-value

Dear List, I would like to ask about package RGtk2 with which I have a problem. I will very much appreciate if somebody could tell me what I need to do. I need to install a package scdMicro and it depends on gWidgetsRGtk2. I am working on MAC, version 10.5.8. When I try to load gWidgetsRGtk2 (or RGtk2), it asks me: "Instal GTK+?" I installed Gtk+ from CRAN, and added a path: export

Dear Experienced R Practitioners, I have 4GB .txt data called "dataset.txt" and have attempted to use *ff, bigmemory, filehash and sqldf *packages to import it, but have had no success. The readLines output of this data is: readLines("dataset.txt",n=20) [1] " "
