Dear, I am using R I'm trying to identify and remove columns and rows in a data frame that are has elements equals. For example in dataframe below. The columns 1, 2,3,4,5 ,6 and 10 (file1) has elements equal then should be removed. How can I ask R to remove those columns with same elements in new dataframe (file2) to result a matrix as follows: file1 1 0 2 2 1 1 5 1 1 1 1 0

Hi, How do I rename the column labels in the table? For Instance, if I have a table like this, and I want to have the column labels changed from "A1 A2 A3 A4 A5" to "Mike Kate Michelle Paul Young" A1 A2 A3 A4 A5 1 33 44 55 66 77 2 3 4 5 6 7 7 8 9 and my text file location is: ""/Users/MAC/Desktop/data.txt" When I type in

hi, Dear R users - I wonder is there a written R function to convert a number to a text, say convert 1 to "one" , 100 to "one hundred". I know in xls. has such a function BAHTTEXT, does anybody know is there a similar function in R ? Thanks. Lin --------------------------------- [[alternative HTML version deleted]]

I apologize for how basic a question this is. I am a Stata user who has begun using R, and the syntax differences still trip me up. The most basic questions, involving as they do general terms, can be the hardest to find solutions for through search. Assume for the moment that I have a dataset that contains seven variables: Pollution, Temp, Industry, Population, Wind, Rain and Wet.days. (This

Hi, I'm trying to do some basic social network analysis with igraph in R, but I'm new to R and haven't been able to find documentation on a couple basic things: I want to run igraph's community detection algorithms on a couple thousand small graphs but don't know how to automate igraph looking at multiple graphs described in a single csv file. My data look like something in

I have installed the kate editor on Centos 6.7 but it seems to be a very old version, 3.3.4, installed as part of kdesdk. On Centos 7 I can simply run 'yum install kate' but, alas, not on Centos 6. What is the recommended way of updating kate on Centos 6? Thank you.

About the media type, my understanding was that text was for actual text, not binary that could be decoded into text. If you think another would be more appropriate, please tell which. If it would be text/x-kate, I'd see

I'm trying to create files that contain a video stream, one or more audio streams, subtitles, and DVD-like chapter information. ATM, I use ogm containers that can handle all this. But although ogm is supported e.g. by xine (including chapters), it seems to be an unofficial hack. Is that correct? I'd like to move to ogg containers, since ogm doesn't support theora videos. My final

Dear R-users, I've recently switched to Ubuntu and I've decided to use Kate to edit my R code. I really like how Kate allows one to simply pipe their code to the terminal. However, I would find it even better if I could actually get the Kate console to display error messages (or any console outputs in fact) in red and my input in a different color. The instance of xterm that Ubuntu

hi, is there a way to make r open the help file in a separate window? i'm quite new to linux(kubuntu) and used to work with r under windows... thanks, katharina

Hello list, We have recently introduced the codecs (optional) parameter on the Ogg media types for easier identification of encapsulated codecs in conditions were it's not feasable to examine the streams directly. I received a comment from the IESG that we should have some sort of list to describe how Ogg mapping strings translate to codec parameter strings, so I went ahead and compiled a

Dear UseRs!, Everything about UseR! 2010 was terrific! I really mean "everything" - the tutorials, invited talks, kaleidoscope sessions, focus sessions, breakfast, snacks, lunch, conference dinner, shuttle services, and the participants. The organization was fabulous. NIST were gracious hosts, and provided top notch facilities. The rousing speech by Antonio Possolo, who is the chief

Hi, this patch adds: - kate support (what else) - this bumps the Javascript API to 1.1 - a few build fixes (note that the adding of -L/usr/X11/lib -lX11 looks suspect to me, that shouldn't be needed, so you may want to leave it out if you think so as well - it's odd as X11 using programs do configure fine on that box) - bad pointer dereference fix (mouse callback) - avoid the input

Hi, I've got a csv format of file. There are seven columns of variables all together, and I've used the diff() function to take the differences between the variables in one column. Now I want to add the differences as the 8th column variable to the csv file. Is there any way that I can do this? Thanks in advance. Carol Gao [[alternative HTML version deleted]]

I'm looking for a plugin for Kate (or any other good text editor for linux) (KDE 3.x) which will highlight the R syntax. The link on www.r-project.org is dead! Any ideas?? Thanks Lars

Hello-- There must be a better way to do this. I have a class method in my model that finds averages and does a few calculations using find_by_sql. The problem I¹m encountering is that all computed columns from MySQL come back as type string. E.g., def self.find_averages(domain_id) if @@domain_average return @@domain_average else @@domain_average =
