I am currently running an R program on a computer with 16 Gb memory (Windows7, 64 bit). When I look at the task manager, I see that only 4 out of the 8 CPUs are being used. Is this due...

Dear all I have found out that the max in the summary of an integer vector is not always equal to the actual maximum of that vector. For example: > testrow <- c(1:131509) > summary(testrow) Min. 1st Qu. Median Mean...

Dear all, I am reading C++ code that is called in an R package. It is not clear to me what SET_STRING_ELT, getAttrib, etc exactly do. I understand that these are macros that have been declared in Rinternals...

Dear all I am trying to build a package, and get the error message: ""packaging into .tar.gz failed"". I have also installed the same package directly from a locally created zip file. In this case, the package is put...

Problem solved, thanks. I've used this instead: COSTaux_AVCAR <- ddply(CARaux,c("SC","YEAR"),.fun = function(xx){sum(xx[ ,costcarin])}) -----Original Message----- From: Jeff Newmiller [mailto:jdnewmil at dcn.davis.CA.us] Sent: donderdag 6 september 2012 14:56...

Dear all I get the following error message when I try to load one specific RData object in R: Error: ReadItem: unknown type 64, perhaps written by later version of R The error message is odd because (a) this RData...

Dear all I try to use Google Maps to calculate travel times per transit between an origin an destination. The guidelines for the search can be found at: https://developers.google.com/maps/documentation/directions/#TravelModes When I submit the...

Dear Bert In the example below, I use just one variable (apparently I mixed up the formatting in the original mail) : two_carmodel_data <- mlogit.data(sample, choice = "choice", shape = "long", alt.var = "cl_vint_com", chid.var = "gezinsid" ) formula...

Dear David Thank you for the suggestion. The following works fine: or_dest <- paste0("origin=",lat_or,",",long_or,"&destination=",lat_des,",",long_des) url_to_google <- paste( "http://maps.googleapis.com/maps/api/directions/json?",or_dest,"&sensor=false...

Dear all, I am trying to estimate a multinomial logit model with mlogit. The data I use for the estimation have the following format (in the full data set, there are many more explanatory variables, but I omit them here...

Dear all, I use R version 2.15.1 on x86_64-pc-linux-gnu (64-bit). I run a simulation where I have to call a series of R scripts in batch mode. When I run the following two...

Dear all, I am estimating a model with instrumental variables using ivreg() (from the "AER" library). When the regressors and the instruments are limited to continuous variables, things work fine. However, I have some regressors, such as "income", for which...

Dear all I use a 64 bit Windows7 system with 16 GB memory. I have run an R script in batch mode with the following command: R CMD BATCH masterassignment_2012_11_09.r --save The execution was terminated with...

Dear all I have written a function, "calibrateCES", in which a function is called, "BPGC", which was written in the enclosure of "calibrateCES". Until the most recent version of my program, "calibrateCES" always used "BPGC" as planned. Following a modification...

Dear all I have bumped into the dreaded 'segfault' error type when running some C++ code using .Call(). I have already undertaken several attempts to debug the C++ code with gdb(), but until now I have been unable to pinpoint...

Thanks for the clarification. The basic error on my side was that I had misunderstood the "digits" option in the summary, I had not understood that even integer numbers might end up being "rounded". Problem is solved now. -----Original Message...

Thanks for the quick response. Concerning your first point: the spaces in " Inno Setup 5" are not spaces between different directories, this was just the name of the directory as suggested during the installation procedure. Anyway, I have now added...
