similar to: computing differences between consecutive vector elements

Dear R-users, When I call Rterm from cygwin, I have no options but typing the exact syntax the first time. If I happen to hit the "delete" key (backspace), R dies when I press enter saying : Error: ... (error concerning the function on the last line of text) Execution halted Perhaps some of you have experienced this and found work arounds? One has to be pretty good to type without

well, sure diff() does it thanks alot Thomas > -----Message d'origine----- > De: Liaw, Andy [mailto:andy_liaw at merck.com] > Date: mardi 27 juillet 2004 16:50 > ??: 'Dewez Thomas'; 'r-help at stat.math.ethz.ch' > Objet: RE: [R] computing differences between consecutive > vectorelements > > > Not exactly sure what you want, but seems like you can

Dear R-users, I've spent most of the day reading R documentation at length but couldn't find something perhaps obvious. I have a dataset made of 3 morphometric variables for a series of watershed [log(slope); log(drainage_area); distance_to_outlet] My aim is to predict the value of log(slope) for pairs of [drainage_area; distance_to_outlet] (sounds like a plain linear model fitting,

Hi all, I haven't been able to find how to assess a variable who's name is constructed with paste. The problem is following: In a data frame, there are 12 columns whose title vary only by a digit, all other part being equal. I would like to compute a operation on a subset these variables and parse them in turn. the data frame "basin.param" contains columns called ratio1,

Dear R-users, I am puzzled by for loops and am kind of ashamed to ask because it is so simple. There must be something I am missing in the way they are executed. Basically, I would like to iterate a given number of time and generate a bunch of stats (that's what loops are designed for, right?). Before doing this I simply want to test simple procedure and see if they work (ie got the syntax

Dear R-users, There are tons of methods out there for fitting independant variables to a dependent variable. All stats books tell you about the assumptions behind OLS (ordinary least squares) and warn against abusive use of the method (which many of us do disregard by lack of a better knowledge). Most introductory text books stop there and don't tell you what the next best option might be. I

Hi all, Thank you for your very useful product but I have a memory problem. I want use you product to migrate 4TB of data (in 150?millions files) When rsync make the list of files it full my RAM and after my SWAP and my server crash. I have 4GB of RAM and 4GB of SWAP Do you know what can I do?? Can I have an option to use an index on disk or something like this?? Thanks in advance

Hi, I could try latest 7zip (4.57) on a triple boot machine (Debian SID i386, x86_64 and native Windows XP SP2), and found something surprising in the results : amd64 at 2400MHz linux32 -> 1814 linux64 -> 1946 win32 -> 2004 So performance is much better in Linux 64 bit than in 32 bit, while both are slower than native windows system. Is it normal, I mean does anyone else obtain

Hi, I currently manage an environment where my Unix and Windows usernames are defined, but different. So, I must use a username map. But I have several Samba servers (one for each NFS package) and I must maintain all these username map files. As we want everybody to map the same way on every Samba servers in a NIS domain, we added the 'Windows user' information to the NIS

Dear R users, I am sorry to ask you such a pathetic newbie question, but how does one append data at the end of a data frame? I am working with GRASS/R library, but the question is about R. I have a data.frame containing the following variables basinID, distoutlet, drainage_area, slope These variables are stored for all pixels of Grass Raster objects. For each drainage basin (basinID), I'd

Currently, LogLevel must be set to VERBOSE to see the fingerprint of an accepted key, and the default LogLevel is INFO. Since this is useful security information, I would like to propose that the 'Accepted publickey' message be modified to include the fingerprint of the accepted key. Is this a reasonable solution? Here is an example log snippet with LogLevel VERBOSE: Oct 1 15:23:24

Hi, I have a issue with OpenSSH 3.7.1p2 and crontab (solaris 8). The crontab will not execute correctly the commands if I edit it by using OpenSSH. client (Solaris 8 / Openssh 3.7.1p2) ---> server (Solaris 8 / Openssh 3.7.1p2). Next, I edit the crontab with "vi" using a console session and I save it without doing modification. The crontab works perfectly now ! ? I have

Hi all, I just joigned this list, so I'm sorry if this problem has already been reported. I'm running Dovecot 2.0.13 on many servers, one for POP/IMAP access, others for LDA, others for authentification only, etc. All servers are accessing a shared file system, based on MooseFS (www.moosefs.org). The FS is mounted using FUSE. All my Dovecot servers have this configuration :

For TTS (text to speech) which TTS engine will be better to use ? I have tested Flite , cepstral (i have not buyed lisence for it trial only) but still thinking may be i have a good option ? -- Best Regards

Hello, I have fit a simple spline model to the following data. Data x y 0 1.298 2 0.605 3 0.507 4 0.399 5 0.281 6 0.203 7 0.150 8 0.101 Model Sp.1=lm(y~bs(x,df=4)) Now I wish to inverse predict the x for y=.75, say. Optimize works fine for a polynomial but I can figure out how to get the spline model into the function argument. Can anyone help me out. Thanks!! Jeff Jeff Morris Sanofi
