I have been using Ruby on Rails for around 6 weeks now (so far I love it), but I''ve gotten to a point in the application where I need to allow the user to upload comma deliminated text files that will get loaded into one of the database tables. Before I get started doing this, I was wondering anyone knows of any examples or tutorials that deal with this. I''d rather do it the right way (if there is one) then try and reinvent the wheel with some hacked solution....

Hello, I have a problem that I am trying to solve and I am not sure how to do it in R. Suppose, that 16 numbers are choosen at random from 0 to 9, what's the probability that their average will be between 4 and 6. I typed the following code: set.seed(100) sample(0:9, 16, replace =TRUE) [1] 3 2 5 0 4 4 8 3 5 1 6 8 2 3 7 6 Is what I got, however I realize the set.seed function

Hi, I've completely forgotten how to do R, and it seems I can't even load simple files correctly. I have two tab deliminated text files (attached, these were test files of the larger data files I'm trying to work with) that I am trying to load into R so that I can merge them. They were originally excel files but I used "saved as" to reformat to text. I don't know if it's relevant, but I use a ma...

...ZjFfG1I@public.gmane.org and jane-+LBmYUDmh58@public.gmane.org get an email when a user registers, and jim-ZTdYKjDxrzcAvxtiuMwx3w@public.gmane.org gets an email when a user takes a test. Any advice? My initial approach would be to create a table called email_events: id key email_addresses (comma-deliminated list of addresses) And then, when a user registers, it looks up the ''User_Registration'' key in email_events and sends emails out to all the email addresses. I haven''t done much work with email handling in Rails, so I don''t know if there''s a better way...

Hi all, I am saving a program's output to a file to be read by another algorithm. But somehow such a simple operation (the reading) fails. I get: Error in read.table("a_corr_data.txt", sep = ",", col.names = T, row.names = F) : more columns than column names Here is the write statement:

...have copy numbers associated with each gene/sample and need these to be represented as the colour intensities on the heat map. There are multiple genes per sample with different copy numbers. I think my trouble may be how I am setting up my data frame. My data frame was created in excel as a tab deliminated text file: Gene Copy Number Sample ID A 1935 01 B 2057 01 C 2184 02 D 1498 03 E 2294 03 F 2485 03 G 1560 04 H 3759 04 I 2792 05 J 7081 05 K 1922 06 . . . . . . . . .
