Hi all, I was wondering whether it is possible to use the lapply() function to alter the value of the input, something in the spirit of : a1<-runif(100) a2<-function(i){ a1[i]<-a1[i-1]*a1[i];a1[i] } a3<-lapply(2:100,a2) Something akin to a for() loop, but using the lapply() infrastructure. I haven't been able to get rapply() to do this. The reason is that the "real"

Dear List, I'd like to call pyhton function from within R. I tried installing the latest version of RSPython: wget http://www.omegahat.org/RSPython/RSPython_0.7-1.tar.gz R CMD INSTALL --clean RSPython_0.7-1.tar.gz I get a compile error (posted below). Did anyone else run against this ? Is there a solution ? checking for python... /usr/bin/python Python version 2.6 Using threads checking

Hi all, I have this problem with lattice that xyplot() won't draw some of my axis labels if the type (i.e. the relation argument) of scales is set as free. For example, in the plot below, I would want it to also show: 1. the labels E1,...E6 below the 10th panel (i.e. 3rd row, 2 col)....just as it is now done below the 12th panel.... 2. as well as the labels (2,4,6,8) on the top of panels 1

Hi list, in the Rglpk_solve_LP function (::Rglpk), on line 26, the function calls a function as.glp_bounds() that i cannot access. i'm trying to alter the Rglpk_solve_LP function to add a line to retrieve column/row dual values. everytime i change the slightest line of code inside Rglpk_solve_LP() [to even add a print] i get a ': could not find function "as.glp_bounds"'

I am trying to get documentation about the random number generator used in "sample". The help for sample does not mention it. Can anyone point me in the right direction. Thanks [[alternative HTML version deleted]]

Hi there, I am trying to write a c++ shared library for R. I need a function which has the same functionality as sample() in R, i.e., does permutation, sample with/without replacement. Does R have internal sample routine so that I can call it directly? I did not find it in R.h, Rinternal.h. Thanks

FWIW, I suspect this is related to the function R_unif_index that was introduced in src/main/RNG.c around revision 72356, or the way this function is used in do_sample in src/main/random.c. 20.9.18 08:19, Wolfgang Huber scripsit: > Besides wording of the documentation re truncating vs rounding, there is > something peculiar going on with the fractional part of n: > > >

Hello, I am trying to get the power function to report the sample size rather than the power. My goal is to input a variety of values for theta and then for the power function to report the corresponding sample sizes. I haven't had much luck trying to create my own function, something along the lines of: f <- function (x) {

Hi I am using repeated meaturement data for my project and I want to use quantile regression with multilevel or panel data in "R." I dont find the basic version of software in R, so I have difficulty in using it. I would also appreciate if anyone more proficient in R could help me how to run this. best wishes  M.A-Vakili Department of Biostatistics Faculty of Medicine Shiraz/Iran

A colleague sent me the following: If you specify probabilities in the 'sample' function and forget to type 'prob=...', then you get nonsense. E.g. sample(1:10,1,c(0,0,0,0,1,0,0,0,0,0)) does not filter '5', while sample(1:10,1,prob=c(0,0,0,0,1,0,0,0,0,0)) does it correctly. I wish this would return an error because the

Dear R-users, I am trying to understand how the 'segmented'-package works to determine breakpoints and slopes of regression lines in broken-line regression models. However, I am not able to repeat the example on the "plant"-dataset, which was reported in the accompanying paper of the package. (V.M.R Muggeo, "Segmented: an R package to fit regression models with

Dear All, I've got a weird problem with my asterisk box which has fxo interfaces (TDM400). Well, the problem is that the interface answers the call, but no caller id is being received. Also, sometimes this error happens: fsk_serie made mylen < 0 Any idea what is going on? Thanks, Kaveh __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has

Hello all, I have 3 time series (tt) that I've fitted segmented regression models to, with 3 breakpoints that are common to all, using code below (requires segmented package). However I wish to specifiy a zero coefficient, a priori, for the last segment of the KW series (green) only. Is this possible to do with segmented? If not, could someone point in a direction? The final goal is to

Dear R-users I am trying to "vectorize" a function so that it can handle two vectors of inputs. I want the function to use phi (a function), k[1] and t[1] for the first price, and so on for the second, third and fourth price. I tried to do the mapply, but I dont know how to specify to R what input I want to be vectors (k and t)(see in the bottom what I tried). I have read the help file,

Hello, I call a function via .Call passing to it a raw vector(D) and an integer(I) The vector is a series K1,KData1, V1,VData1, K2, KData2, ... where the integer K1 is the length of Data1 and similarly for Ki (wrt Datai)(similarly for V*) There 2*I such pairs( (Ki,KDatai), (Vi,VDatai)) The numbers Ki(and Vi) are written in network order. I am returning a list of I elements each element a

Hi, After seeing in "pbx/ael/ael-test/ael-test5/extensions.ael" some interesting use case of RealTime to store extension data (forwardto, dnd, ...) i started to play with it. To my surprise the two applications RealTime() / RealtimeUpdate() have been deprecated in favor of the REALTIME() function. While it's not a big deal for the write part since it's only a matter a shifting

Good day, The use of "rounding" also doesn't make sense. If The number is halfway between two integers, it is rounded to the nearest even integer. > round(2.5) [1] 2 -------------------------------------- Dario Strbenac University of Sydney Camperdown NSW 2050 Australia
