Hi all, I have imported a value 3:00 from Excel into R using read.csv. I want R to recognise it as 3:00am (time data). How do I do it?

Hi all, I have a dataset similar to the following Name Date Value A 1/01/2000 4 A 2/01/2000 4 A 3/01/2000 5 A 4/01/2000 4 A 5/01/2000 1 B 6/01/2000 2 B 7/01/2000 1 B 8/01/2000 1 I would like R to remove duplicates based on column 1 and 3 only. In addition, I would like R to remove duplicates based on the underlying and overlying row only. For example, for A, I would like to remove row 2 only

Hi all, I have a dataset which consists of 2 columns. I'd like to plot them on a x-y scatter plot and fit an exponential trendline. I'd like R to determine the equation for the trendline and display it on the graph. Since I am new to R (and statistics), any advice on how to achieve this will be greatly appreciated. Many thanks, Chris -- View this message in context:

Hi all, I have written a note near each of my graphs using mtext. mtext(text,side=1,line=4,cex=0.5,adj=0) Then I have exported the graphs as a PDF file. pdf(file=name,paper='a4',width=7.27,height=10.69) The mtext appears OK in R. But it looks like it is bolded in the PDF file. http://n4.nabble.com/file/n2016971/graph.png I am not sure if this is actually my monitor/computer's

Hi all, I have got 27 graphs to export (not a lot...I know!). How can I fit all of them into a single file like PNG without adjusting the size of the graphs? What's in my mind is like pasting graphs into Word, in which I can just scroll down to view the graphs. Thanks for your attention. Much appreciated. Chris -- View this message in context:

I''m working on an application that does extensive database searching. These searches can take a long time, so we have been working on moving the searches to a backgroundrb worker task so we can provide a sexy AJAX progress bar, and populate the search results as they are available. All of this seems to work fine until the size of the search results gets sufficiently large, when we start

We recently tried upgrading openssh from 2.5.2p2 to 2.9p1 and discovered that it no longer worked to feed the output from a remote command into a pipe, unless the output was short and the pipe was very fast at processing its input. Example 1: ssh remote_machine some_command | less (where "some_command" generates a lot of output) now fails after the first screenful, with a

Hi everyone, I have been searching for answers for the following questions but I don't have much success. The following questions may actually be quite simple. Any help would be greatly appreciated. (1) I have written a script which requires user input. I am using the readline() command.However, everytime when I run the script, R does not wait for the user input and proceed to the next line.

Dear all, I'm stuck with a problem using plyr to process a rather large junk of data. What I'm trying to do is applying a moving average to all the subparts of the dataframe (the example data can be found here https://dl.dropboxusercontent.com/u/2414056/testData.Rdata). require(plyr) load("testData.Rdata") applyfilter<-function(x){ return(filter(x,rep(1/5, times=5))) }

I have a data set like this in one .txt file (cols separated by !): APE!KKU!684! APE!VAL!! APE!UASU!! APE!PLA!1! APE!E!10! APE!TPVA!17122009! APE!STAP!1! GG!KK!KK! APE!KKU!684! APE!VAL!! APE!UASU!!

Hi all, I''m going over win32-file this weekend. I''m creating instance methods for setting (or unsetting) the various file attributes. So, you can do something like: f = File.open("foo.txt") f.archive = true f.hidden = true f.close This works for the basic attributes, but it requires extra work for others. Specifically, I am having trouble trying to set the

Hi, I am new to programming and R. I am reading the manual and R books by Dalgaard and Veranzo to help answer my questions but I am unable to figure out the following: I have a data file that contains 1080 data points. Here's a snippet of the file: [241] 0.3603704000 0.1640741000 0.2912963000 NA 0.0159259300 0.0474074100 I would like to break the file up into 30

Hi, I have 50 files whose names are XYZW01Genesis_ABC.mp3 XYZW02Genesis_ABC.mp3 ....... XYZW50Genesis_ABC.mp3 As you can tell, the only difference across the files are 01, 02, 03,....50. I would like to rename them to 01Gen01.mp3 01Gen02.mp3 ....... 01Gen50.mp3 If I store them in one folder and write an R code in that folder, how can it be done? Thanks, John [[alternative

I am trying to setup my Sun running samba 1.9.18p10 so that it can backup my dept's PCs. I can get it to work manually using the smbclient command with no problem. What I would like to do is have a script that is able to take a list of PCs, determine if a PC is online, backup that PC, then move on to the next one. If a PC is down, it can report an error to the admin to state that the

Hi Folks, I have been working to fix BackgrounDRb memory usage as such. Ruby1.8 GC isn''t fork friendly and it seems to use a lot of memory because when you fork, it sets a bit in all the objects in global scope which causes OS to all pages in child process. A classic solution is to use fork and exec, rather than just fork. Its working and pretty stable, but you loose ability to pass

Hi all, Thanks to Wayne and Park, I''ve got something like this now: static VALUE file_set_compressed(VALUE self, VALUE rbBool){ HANDLE h; BOOL rv; DWORD dwBytesReturned; int fn; USHORT inBuf = COMPRESSION_FORMAT_DEFAULT; if((rbBool != Qtrue) && (rbBool != Qfalse)){ rb_raise(rb_eTypeError,"Argument must be true or false"); }

Hi all, Any ideas for the question below? I know how to do this in theory - make the ''inherit'' flag true, and set the ''stdout'' and ''stderr'' startf_flags hash options to something in the startup_info hash, but I wasn''t sure how to do this in practice. It would be nice if the answer could be something like this: require

Hello all. I wish to read a large data set into R. My current issue is in getting the data so that R would be able to access it. Using read.table won't work since the data is over 1GB in size (and I am using windows XP), so my plan was to read the file chunk by chunk and each time move it into bigmemory (I'll play with that when the time will come, maybe ff is better ?!). I encountered
