similar to: Importing CSV File Using rails

For some reason, I''ve posted this question to this forum 4 times now and it never appears in the daily consolidated email I get daily? I''ve written a routine allowing the client user to declare where their .csv import file resides and then send it to the server to import the many rows into an existing model table, and then throw it away.

I am writing a application where there is a lot of data in an old Filemaker program that I am going to need to do a 1 time import...1 main table and 2 related tables. I can get the data from Filemaker into a dbf or csv or Excel file without problem. Is anyone aware of a utility for postgresql or a rails plug-in that might make this easier? I am worried about Rails import since I can''t

I'm new to R. I have a mac (OS10.6). I have converted an Excel file to a csv to import into R. I have used many methods to import the file, most do not work, the best so far is: filename <- read.csv(/Users/Desktop/csvfile.csv", header=T, sep=","). I have also tried taking out the header and sep lines and it still imports fine. Regardless of what I do, it always brings in

Dear R experts, I am trying to import some data from some Excle files into R. My Excle file contains about 50 sheets. One solution I can think about is to convert my Excle file into csv file first and then load data into R using 'read.csv'. But it seems to me that 'read.csv' only supports reading one sheet (or 'one file') each time, so that seems I have to create 50 csv

Hello everybody out there using R, I'm using R for the analysis of biological data and write the results down using LaTeX, both on a notebook with linux installed. I've already tried two options for the import of my data: 1. Import from a SQLite database 2. Import from individual csv files edited with sed, awk and sort. Both methods actually work very well, since I don't need advanced

Hi guys, another question today: If I import an external csv-file with headers (with read.csv2), the blanks are interpreted as points. So "Test 1" becomes "Test.1". Is there a way to change this? Thanks, Thomas I'm using XP and R 2.6.1 [[alternative HTML version deleted]]

There is a recurring need for importing large csv files quickly. David Baird's dataload is a standalone program that will directly create .rda files from .csv (it also handles many other conversions). Unfortunately dataload is no longer publicly available because of some kind of relationship with Stat/Transfer. The idea is a good one, though. I wonder if anyone would volunteer to

Hello, I need some help getting started with data analysis. I’m having trouble getting R to read my data file.
