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 solut...

...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 locks in the number I get every time. My question is in order to run a true random sample, wouldn't I have to use the runif function? And then deliminate the sample to show the numbers that lie between 4 and 6? If that's the case, how do I do that? Davia S.

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...

...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...

...,",col.names=T,row.names=F) Here is the read statement: a_corr_data <- read.table("a_corr_data.txt",sep=",",col.names=T,row.names=F) Nothing happens in-between (these actions are just 10-30 secs apart). I tried to export/import without col.names, also tried different deliminators ("/t") but the same error pops up again and again. I am already quite unhappy with this. thanks, N. -- View this message in context: http://www.nabble.com/Unable-to-re-import-a-table-that-was-just-exported-to-a-file-tp23248010p23248010.html Sent from the R help mailing list archi...

I think my trouble may be how I am setting up my data frame.
