Dear R-users, I am a newbie to R so please excuse this naive question for which I couldn't seem to find online answers. I have this data frame containing a series of locations through time (x,y,z,t). I would like to compute the difference in x, y and z between t-1 and t. Sounds easy enough, but how on earth does one loop through vector elements and compute this difference? Thanks Thomas

Dear ALL, I fear my question has already been answered many times before, but I haven't fund that in archives... I am working on spatial datasets and, in most arrays I'm handling, there are two columns dedicated to (x,y)-coords. For different reasons - notably to draw image() plots, I need to have these two columns sorted in increasing order. But sort() and order() seem to apply to

I cannot operate lattice plots, notably those in package gstat, within for() loops. (I can neither read such graphics included in a .R (or .txt) file with the source() function). However same commands executed one by one don't fail. Could you please help me find a means to execute lattice plots inside a loop ?

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

Hi, I try to compile Dovecot with the *Ubuntu* patched sources but I got this error during the compilation: ./.libs/libsieve.a(script.o): In function `sieve_script_parse': /src/dovecot-1.0.rc17/dovecot-sieve/src/libsieve/script.c:140: undefined reference to `yylineno' ./.libs/libsieve.a(sieve.o): In function `sieveerror': /src/dovecot-1.0.rc17/dovecot-sieve/src/libsieve/sieve.y:568:

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,

Hello list, I am trying to avoid "Rifying" some of my SAS code to generate ROC plots, and the logistic.display() and lroc() functions in the epicalc package do what I want. However, I must generate my logistic model with bigglm because I have 1) limited hardware, 2) ~2.5 million rows, and 4 categorical and 2 continuous independent va...

Update taking into account the answer of Prof Ripley. ___________________________________________________ Below is a reproducing example that produces the crash. If I do exactly the same in R 3.1.2, it works perfectly. I have the lastest libcurl library (curl @7.40.0) installed So, perhaps indeed that the problem originates from RCurl, but the problem appears only in R 3.2. But before to

Hi all, I am planning to do clustering for my company's asterisk servers. I dont know much about it, just read some articles on the internet and learned how to use DUNDi and some basic information about clustering. What I need to know is: 1. can i register end user with multiple asterisk servers at a time? 2. If not, Can I re-route registeration requests to different servers using 1 asterisk

Hello eveybody, I am studying the vertical distribution of plankton and want to study its variations relatively to several factors (time of day, species, water column structure etc.). So my data is special in that, at each sampling site (each observation), I don't have *one* number, I have *several* numbers (abundance of organisms in each depth bin, I sample 5 depth bins) which
