similar to: Newbie guidance: Dates and grouping

Dear colleagues, I have extracted the dates of several news stories from a newspaper data base to chart coverage trends of an issue over time. They are in a data frame that looks just like one generated by the reproducible code below. I can already generate a histogram of the dates with various intervals (months, quarters, weeks years) using hist.Date. However, there are two other

Hello: I have done this before but cannot figure out how to do it again. I would like to graph campaign evolution of news stories on certain topics. The campaign time period is as follows: campaign<-seq.Date(from=as.Date('2011-09-06'), to=as.Date('2011-10-5'), by=1) I have a table of newspaper story frequencies containing a certain word that can be turned into a data.frame

The "merge" command is creating duplicate column names in a dataframe that is the result of the merge. The following is the 'merge' command: x <- merge(invType , allocSlots , by.x = 'index' , by.y = 'indx' , all.x = TRUE ) The 'invType' dataframe was the result of a previous merge and has the following column names that are

Hello: I have a series of newspaper articles from a Canadian newspaper database (Canadian Newsstand) that look just like below. I've read through this vignette (http://cran.r-project.org/web/packages/tm/vignettes/extensions.pdf) about creating a custom reader to extract meta-data, but I can't understand how to apply this in the context of a text document, rather than in the tabular format

Hi, I have a question about: /sbin/installkernel I believe this line: LINK_PATH=/boot and usage of this variable... is a bug. What do others say? Using this script, as-is, I would need to chroot to make it work properly for a alternative INSTALL_PATH, right? who the heck is tyson? why did he re-write this? # # /sbin/installkernel - written by tyson at rwii.com # Cheers, AZ

I am having difficult getting the hosts allow/deny to work with IP ranges or netmasks. Ideally I would prefer to use the IP/Netmask method, e.g. 111.22.33.0/255.255.255.0, because we have a flat ATM network with multiple class C's (netmask is really 255.255.252.0). This, however, doesn't work!! I can't do 111.22.33. either... I can't even do specific IP's, e.g. 111.22.33.44

I have a multi-homed server with interfaces into two VLANs (one Unix and one NT). I need for all Samba traffic to go through the NT VLAN interface (which is not the primary, of course). Under 2.0.5a I was able to do this with the "Interfaces" option by specifying the NT interace first (I did not do the "Bind Interface Only"). However, 2.0.6 seems to ignore this setting which

I''ve got a database with several tables. I''d like to create scaffolding for separate CRUD interfaces for several of these tables. I''m hoping that the scaffold generator can create the CRUD code for all these tables in ONE controller, but I don''t know how to tell it to do that, if it can. Can anyone verify if this is possible? Thanks, David -- Posted via

I have installed rsync on my Windows and Linux PCs. I would like to use it to copy a folder from Windows to Linux on a regular basis as part of my backup regime. It works but always prompts me for a password. Is there any way to make Windows pass authentication automatically so that I can batch this process?

Hi all. Usually for in-house use and SSL I would just generate a self-signed certificate because most clients either ignore it or only ask the first time the account is configured. In terms of offering the service to our customers is there any value of getting someone like thawte or instantssl to sign a certificate for imaps/pop3s/smtp? Also, is there a configuration directive for dovecot

Dear colleagues, I have a series of newspaper articles in a text file, downloaded from a text file. They look as follows: Document 1 of 100 \n \n \n Newspaper Name \n \n Day Date I have a series of grep scripts that can extract the date and convert it to a date object, but I can't figure out how to grep the newspaper name. There is no field ID attached to those lines. The best I can come

Preface: I''m trying to find my way through the "Build Your Own Ruby on Rails Web Application" book. I''m completely new to programming and am having a hard time figuring out the differences between rails 2.0.2 and what''s in the book so please forgive me if this is a stupid question. I''m confused because I finally thought I''d figured out the

I went through a tutorial at http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html?page=1 to get started with RoR. I really like the idea of the scaffold construct, but I can''t seem to get it to work the way it was described in the tutorial. I''ve got a mysql database that is properly configured, and a table called ''quotes'' with a column called

Hi, We have dedicated puppet master boxes, which basically only run a mongrel/puppetmasterd (6 instances), an apache proxy for mongrel and puppetd. Recently puppetmasterds seemed to have leaked almost all of the RAM, and the thrashing made the box painfully slow. We restarted the puppetmasterd processes, and started collecting some statistics. Attached is a graph of memory usage on one of the

Hi there! I experienced an issue with routing. Basically, I''m trying to follow step-by-step the Rails'' official guides process for what concerns the nested routing. So, I have Newspapers that has_many :ads , and :ads belongs to :newspaper . What I did was simply trying to obtain an URL like this: http://localhost/newspapers/1/ads/1 but when I set routes.rb in this way:
