Hi, I have been brought back to the "R-Side" from MatLab. I have used R in graduate econometrics but only for statistics and regression (linear and nonlinear). But now I need to run general nonlinear optimization. I know about the add-in quadprog but my problem is not QP. My problem is a general nonlinear (obj funct) with linear constraints.I know about the "ms" and

r-help, Is there a package available for R which allows you to export data directly to .xls, much like exportData(foo,"foo.xls","EXCEL") in S-PLUS ? If not, is anyone working on this, or thinking about working on this? I apologise in advance if this question has already been answered. Many thanks, Matthew

Hi, I have recently started using R again (switched from MatLab) and have a question regarding programming. How can I set up a file that will run several lines of R code? For example, in Fortran and DOS this used to be done via a batch file, and in MatLab I would write the code and save it in a script file, e.g., Test.m. An example of what I am trying to do is the following:

Hi, Quick question on reading data. I am running simulations but want to allow the user the option to define the number of simulations. How can I have R read-in user data entered from the keyboard? Is there a difference for reading in numeric and character data? For example, I am trying to write the following in R: Enter Number of Iterations? <<<the user then enters a number say Y

Hi, I have a couple of quick questions regarding R. 1) I have a ".First" function that automatically loads the quadprog package into the workspace. The .First function resides in R and is only saved if I save the workspace. The exact function is as follows: .First<-function() { library(quadprog) } Is there any way that this function can be saved outside of R? That is, is there

I had an open session working in R and I regularly save the image with save.image(). However, after a period of inactivity of a few days. I quit the session. Now, when I try to restart R and load the same image I get the following result: > load("y:/grm/sdata/.rdata1") Error in load("y:/grm/sdata/.rdata1") : an xdr real data read error occured Can someone explain the cause

Hi, I have the following code from Splus that I'd like to migrate to R. So far, the only problem is the arima.filt function. This function allows me to filter an existing time-series through a previously estimated arima model, and obtain the residuals for further use. Here's the Splus code: # x is the estimation time series, new.infl is a timeseries that contains new information # a.mle

...above=below+1 v = d$y[below] * (q-d$x[below])/(d$x[above]-d$x[below]) + d$y[above] * (d$x[above]-q)/(d$x[above]-d$x[below]) if(k==1) V = matrix(v,1,1) else V = diag(v) w_CQR = Binv %*% v; w_CQR = w_CQR / sum(w_CQR) #----- Use the estimated optimal weights to actually estimate beta (with EQR and CQR) and evaluate how well it does print(paste(m, distr, k)); readline() ################ THE NEXT LINE CRASHES AT RANDOM: fit_cqr=try( rq.fit.hogg2(x=cbind(X),y=y,taus=tau,weights=c(w_CQR)) ) } # for(k in 1:K) } # for(distr in distributions) } # for(m in 1:M) [[alternative HTML ver...
