Hello.. I am currently working on running random forest to make predictions. For that I have a bunch of .dbf files from shapefiiles. Earlier I was running random forest on those dbf files individually but now I have >1,000 such files and procesisng one by one is not an option. I started by trying to read multiple dbf files as: >setwd (..) >a=list.files() > for (x in

Hi there, This is summary and patch for a bug in read.dbf, demonstrating in Message-Id: <20050818150446.697835cb.stanimura-ngs at umin.ac.jp>. After consulting Rjpwiki, a cyber-community of R user in Japan, the cause was found, and the patch of solution was proposed. Overflowing occurs when we use read.dbf for reading a dbf file having a field of longer signed integer. For example, $

Dear UseRs, I did not have any answer to my previous message ("Is there a way to define "manually" columns width when using write.dbf function from the library foreign ?"), so I tried to modify write.dbf function to do what I want. Here is my modified version : write.dbfMODIF <- function (dataframe, file, factor2char = TRUE, max_nchar = 254, width = d) {

Hi I know that it is very easy to import data from a dbf file to R, by saving the data as csv, for instance. However, I have several hundreds of files to do that. So, I thought of using RODBC to read the dbf files and save it as data.frame. However, I cannot even start (this is my first time using such package): > library(RODBC) > bdades <- odbcConnect("prova.DBF") Warning

Hello, I'm newbie in R and I have a problem exporting a table with many columns to a dbf file. I found an error when I open the result DBF file on other software and also importing it on R again. Here a example snippet of the problem (on a GNU/Linux OS): http://pastebin.com/0SMJqqwb Is it a bug? Thank you, Nacho V [[alternative HTML version deleted]]

I have a heavy DATA saved in dbf format. What I want is to bring that data to R with SQL statements. Like: I want columns 1, 4, 5 and only when column 4 > 30. Sorry asking it here instead of keep searching in manuals, but it seems that there are too many ways of doing it. So what's the appropriate package that I need to work it, considering also that im dealing with lots of gigas so the

Hello Arnaud, You posted this question a long long time ago, however I found your answer so I decided to post it anyway in case somebody else have the same problem as you and me. You were actually very close in finding your solution. The function DoWritedbf is an internal function from the foreign package. To access it outside of the package just do: foreign:::DoWritedbf so in your line:

Hi List, I wanted to provide the solution that proved to fix this problem. On this particular server I observed we had consumed all memory resources and were using a decent sized swap file.

Dear all, I am basically a GIS user and am new to R.

Hi - I need to export data to openoffice base, where one of the elements is a long character vector (>255 characters.) write.dbf exports it as varchar, truncating the data. Any idea how to do this? thanks, -eduardo

Hello. I am trying to acces to a software in a network, from a terminal. This terminal works on Windows, so I use Wine. I could execute the software, but some errors appear.

good morning This question is not a stats question per say but a data management and lattice plotting problem. I apologize now if I'm asking an inappropriate question to this gracious group.

Hi List, Second attempt to get this issue diagnosed and solved. Samba Version 3.0.28el4 CentOS 4.7 The behavior is as follows when accessing Fox Pro dbf files.

Hello all, I have a samba 2.2.1a server running as the PDC of my network on a Mandrake 8.0 system with a reiserFS partition.
