similar to: filehash does not install on FreeBSD

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 have been using filehash for a while. It has performed very well. However, 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 =

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

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

Hi Phil: That's EXACTLY what it is. Thanks so much. It's nice to know that the R Gods don't hate me. I hope it's okay that I'm going to cc r-help in case this thread comes up in the future and also so that other people who might want to help know that it's solved. Thanks again.

I usually just run my R programs at the R command prompt but for my latest one I want to save any output that gets written to the screen so I am trying to use R CMD BATCH and send the output to an output file. I realize I could use sink at the prompt but I'd rather try to do it this way because I know that I used to do this in S+. So, I wrote a simple one line program called test.R which

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)"

I've run into a problem with lazy loading on a Linux system when trying to install the Matrix package (version 0.995-16) which didn't happen with version 0.995-2. The problem is not with a x86_64 system: it's a 32 bit machine, the exact description I don't have right now (R-2.3.1). The message looks like this: Error in match.call(fmatch, fcall) : unused argument(s) (x ...) In
