R-experts, I have a bunch of files (by date) that I can read into dataframes as below. df$today: identifier rtgmdy rtgmdy_dt rtgmdy_watch rtgmdy_nowatch rtgmdy_watch_dt rtgsp rtgsp_dt 310000031 Aa3 20050701 Aa3 NA AA- 20050510 310000086 B1 20070920 B1 NA B+ 20070828 310000106 Baa2 20040326 Baa2 NA BBB 20051003 310000170 Baa3 20070601 Baa3 NA BBB+ 20051024 310000225 Ba2 20070601 Ba2 NA

Hi all: I have a directory of files as in -------------> bunchafiles <- list.files(path="/data/2.3/2006", pattern="returns", full.names=T,recursive=T) .... Each file is a bunch of returns for a particular date (unique). There are like 252 files or so. With a custom function myread (below), I define a vector ----- res <-

Hi, I am doing the following: 1. I have a list of files.. Files1=list.files("some directory",pattern="some pattern") 2. I define a list as res=vector("list", length(files1)) 3. I read all the files into this list: res=lapply(files1, read.csv) I now want to rowbind all the items in the list into one big mass (all files have same number of columns). I tried

I have a dataframe as follows: Date time value 20110620 11:18:00 7 20110620 11:39:00 9 20110621 11:41:00 8 20110621 11:40:00 6 20110622 14:05:00 8 20110622 14:06:00 6 For every date, I want to extract the row that has the greatest time. Therefore, ending up like: 20110620 11:39:00 9 20110621 11:41:00 8 20110622 14:07:00 6 I am using for loops (for every date, find largest time value) to do

http://stackoverflow.com/questions/9535653/file-rename-on-ext3-appears-to-break-posix-spec I posted the above to stackoverflow - I am running a test does repeated file renames to a target file in one thread, and repeatedly reads that target file in another thread. This works fine except when there is a hard-link to the file being renamed to the target file. In this case the reading thread hits

Hi, I saw some ref to R on HDF site and found some e-mails regarding them on Feb. Has there ben any developement on either of these software (HDF or netCDF)?

Hi, First time on this list. Here it goes I am trying to find Loess. I could not find it on the windows version. Is there one in either Unix version of R or some C program somewhere? I tried one from http://netlib.bell-labs.com/netlib/a/, but I cannot get it to compile due to problem with missing lib (I think): cc -o gas.x gas.o loessc.o loess.o predict.o misc.o loessf.o -llinpack -lcor -lm

I have just installed openssh on my Sun Cobalt Qube, running Linux. The shell interpreter for the rc script forces /sbin/sh. This is defined in opensshd.init.in. This shell does not exist on this implementation of Linux. I have written about this in (much more) detail at http://blogs.sun.com/roller/page/DaveLevy/20060104. NB This would seem to me to be a common problem but I havn't found

Hi, Is there any docs on R.dll? Or is it "use the source Luke" time? (The NT 0.63.1) Can anyone give me pointers on where to look? I am trying to wrap it under a GUI. The bdr release has examples, but it seems to be limited in scope. Has anyone compiled R under VC++. I see that the older version has been compiled under VC++ at some point. Is this best place to start to see how to

Hi, Is there any possible way to connect to VB, VC++, Delphi, Python, etc... to R? I am trying to put some nice GUI using something like VB and use R as a back end for computations. I search through the FAQ and help archive, but could not find any. I am willing to look at any tools on Sun/Solaris environment as well (Like C or Python or Perl). If anyone can share some examples, pls let me

I apologise for not knowing the answer to this, especially as I saw it was discussed on the mailing lists but can't find the original article (even searching the archives). Our support teams would like a single smb.conf that can be used as a default world-wide. (allowing for a minimal modification of the "workgroup=" field) This means that you're stuck for what to put in your

Hello: I modified benchmark used in http://www.informatik.uni-frankfurt.de/~stst/benchspl.txt now the attached code will work with R, except for last test for some reason (Sorry ran out of time to play with this). Immediate problem is that R does not show fraction of seconds. So, that kinda makes comparison some what hard. I also looked at memory and CPU usage on NT console. R seems to go
