What are the possibilities of file manipulation in RoR? How do you create a .html or .rhtml file with ruby to be placed in the public folder, with custom content? Btw, where is RoR root? Is that ''public''? -- Posted via http://www.ruby-forum.com/.

Is there a cheat-sheet anywhere that describes how to do SQL-like manipulations on a data frame? My knowledge of R is rather limited. But from my experience it seems as though one can think of data frames as being similar to tables in a database: there are rows, columns, and values. Also, one can perform similar manipulations on a data frame as one can on a table. For example:

...of one caller but without manipulating the audio that comes from another caller. I have read about something called JACK but i don't know if i can use it for this (or how to use it). I am playing with audiohooks now, but I don't think I can change only my voice - whole audio in a call gets manipulated.

Hi,all I only got the time data such as: tms<-c("19:30:23","18:39:10".....) I want to manipulate this time series data. For example, plus one second(or minute) or minus one second This data only has the time(h:m:s), without the date.

Can someone tell me how to do this...Given the following line: exten => *97,3,VoicemailMain(${CALLERIDNUM}@default) Is it possible to add some logic to manipulate the CALLERIDNUM to send back 801 even if the extension is 601 and 901 even if the extension is 701?

Hello, I am stuck with the following problem. Consider the vector: vec <- c(2,4,6,9,10) I now want to use R to manipulate the vector as follows: [1] 2, 4, 2, 6, 2, 9, 2, 10 In words, the first element of the vector should be placed in front of each following number. Which R commands do I need to achieve that? Cheers -- View this message in context:

Is R an appropriate tool for data manipulation and data reshaping and data organizing? I think so but someone who recently joined our group thinks not. The new recruit believes that python or another language is a far better tool for developing data manipulation scripts that can be then used by several members of our research group. Her assessment is that R is useful only when it comes to data

Dear all, I want to manipulate a character string such as ex<-"cbind(data$response1,data$response2)" in R in two ways: 1) extracting the "response1" portion of ex 2) replacing "$" with "." I am wondering that is it possible efficiently doing these in R? Best Ozgur -- View this message in context:

Hi, I haven''t done any associations before, so please forgive my incorrect use of terminology... If I set up a has_many :through association, can I manipulate the associated instances directly (like an Array), or do I need to manipulate the join model? For example, suppose I have two classes and the associated join model: class foo has_many :foo_bars has_many :bars, :through

We have a Redhat 7.2 server running(we think) samba 2.2. We updated 3 Win2K machines from SP2 to SP3 and now we have some problems. While they all can browse, read and write to samba shared directories, they cannot manipulate any open files in them. We do have one other Win2K machine that works with no problems but I cannot find any differences in its setup and the other three. I checked the

Hi Adam, I hope this is what you wanted: dat1<- read.csv("example.csv",sep="\t",stringsAsFactors=FALSE) ?str(dat1) #'data.frame':??? 102 obs. of? 5 variables: # $ species? : chr? "B. barbastrellus" "E. nilssonii" "H. savii" "M. alcathoe" ... # $ period?? : chr? "dusk" "dusk" "dusk"

I have uploaded the property data from Lee County Property Appraiser into R, but my problem is that I am unable manipulate and use many of the columns because they are classified as factors. I think this is because the values represent selling prices and therefore have $ in front of them. I tried using as.integer but this funtion converts the values into a totaly useless form. Is there a way to

Hi, there, I have a simple data manipulation question for you. Thank you for your help!

Is there a way a function ('parent', say) can manipulate the ... argument, and then pass the manipulated value into another function ('child', say) that it calls? What I'm trying to do is to use some plotting defaults within 'parent' that are not part of parent's argument list, but to let the use over-ride these defaults if they choose. A sketch is below. parent <- functi...

Dear All >From my previous posts , I learned from you to make use of 'sort' , 'grep' , and 'grep -v' to manipulate text files . At now, I have generated a large text file from my autoexpect script. To be more specific, I need to find how many distinct records are there in say column#1? How can I filter out the distinct records with number of occurances less than a

Dear Everyone, I try to automatically manipulate the data of a variable (class = factor) like x 220 220a 221 221b B221 Into two variables (class = numeric) like x y 220 0 220 1 221 0 221 1 221 1 y has to carry the information about the class (number or string) of the former x-Variable. I could do it by hand like x[x == "220a"] <- 220

This is concerning an Asterisk 1.4.18 server. We have approximately 70 DID numbers. Incoming calls are placed into the "incoming" context (by zapata.conf) and are routed based on the dialed number. I want to do some manipulation (CallerID name override) to all incoming calls before they are routed. I would prefer to avoid duplicating the necessary code in each DID extension stanza,

Dear all, I recently read the book " R data preperation and manipulation using sqldf package" by Djoni Darmawikarta However, I have a problem with manipulation of dates using this package, I do not get the expected results.
