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]]

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

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>.

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

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

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.

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:
