Dear R users, I need to to the the following. Let a= 1 2 3 4 5 6 and b= -1 -2 -3 be (2x3) matrices. -4 -5 -6 I need to combine the two matrices into a new (2x6) matrix like this: ab = ( 1 -1 2 -2 3 -3 ) 4 -4 5 -5 6 -6 How can this be done in R? ----------------------------------------------------------------- ?????? ???

Hello! After I type "upsmon", in syslog the following message appears: Aug 16 14:11:09 marto upsmon[7731]: Master privileges unavailable on UPS [Inform@localhost] Aug 16 14:11:09 marto upsmon[7731]: Reason: Access denied Can you tell me where my error is, my configuration files are: ups.conf: [Inform] driver = powercom port = /dev/ttyS0 desc = "inform guard" linevoltage = 220

Dear R users, I have a lot of experience with traditional R graphics, but I decided to turn to trellis as it was recommended for spatial graphs by the sp package. In traditional R graphics I always first set the size of the device region absolute units (e.g. mm) and then I firmly fix the inner margins with mai and the outer margins with oma also in absolute units. What is left from the device

Hello! I need to perform weighted multidimensional scaling analysis(WMDS). I did rsitesearch, googled, but I could find no info on how to perform WMDS using R. In several places they say it is possible with the ALSCAL algorithm, but I could not find the relevant function to carry it out. ----------------------------------------------------------------- ???????? ?? ??????? ?? ??? ???????????!

Dear R users, I need perform structural analysis on a no intercept VAR model. Unfortunately the functions irf.VAR and dfev that come with the MSBVAR package only work with objects output by the reduced.form.var function, which seems to only evaluate VAR models with intercept. Is there a way to suppress the estimation of intercept term in reduced.form.var? Do I need to modify the code, and if I

Dear forum, I need to create biplot graphic. I took a look at the code of the biplot.default function from the stats package and I found that the arrows for the variables are multiplied by a coefficient of 0.8 before plotting: ... if (var.axes) arrows(0, 0, y[, 1L] * 0.8, y[, 2L] * 0.8, col = col[2L], length = arrow.len) ... I have no idea why this is done. Could somebody

Dear nut users, I am running nut-2.6.0 on Slackware-Linux-13.37.0 with kernel 2.6.37.6. I am trying to get the software work for a repotec UPS with model name: RPT-1003AU. The UPS communicates with the computer via USB. I know that the model is not officially supported but I want to try out whether it will work with some of the repotec drivers. Here is the result with the genericups upstype=13

Dear R users, I am using the vars package to calculate the impulse response functions and the forecast error variance decomposition of a VAR model. Unfortunately I do not know whether these functions assume unit or one standard deviation shocks. I tried to look into the code of these functions, but in vain: neither irf, nor vars::irf, nor vars:::irf output the code of the functions. Does someone

Dear R users, I need a produce a plot with a single panel and a few lines on it. Each line represents a different data set. The line types must be "h", i.e. ?histogram? like (or ?high-density?) vertical lines. The problem is that the vertical lines comprising a plot line of type="h" are drawn from the y=0 line to the (x, y) locations. What I need is vertical lines drawn from

Dear R users, I need to plot to perpendicular straight lines. However, although I set the coefficients so that the lines are perpendicular, they do not look to be so in the plot. Here is a minimal working example: plot(x=c(-1, 1), y=c(-1, 1)); abline(a=0, b=1/sqrt(2)); abline(a=0, b=-1/sqrt(2)) Please tell me if the same problem is valid by you. I am running R-2.10.1 on Linux. Is there a way

Dear R users, I am running R-2.15.1 in Linux Slackware64-14.0. Here is my minimal working example: testfun <- function (x) { a <- 0; sapply(X="a", FUN=get, envir=sys.frame(which=x)); } Inside R, that is R called from within a Linux terminal, the following code works: testfun(x=5) print(testfun(x=6)) But within rkward the above code fails and the following works: testfun(x=1)

Hello! I am running R-2.3.1-i386-1 on Slackware Linux 10.2. I am a former matlab user, moving to R. In matlab, via the cftool, I performed nonlinear curve fitting using the method "nonlinear least squares" with the "Trust-Region" algorithm and not using robust fitting. Is it possible to perform the same analysis in R? I read quite a lot of R documentation, but I could not

Hello! I am new to R. I could not find a function analogous to matlab's function buffer, which is used in signal processing. Is there such a function in R? What I need to do is as follows. If I apply the function to the vector c(1:5) for example with a window length 3 and overlapping 2, I need to get a matrix like this: 1 2 3 2 3 4 3 4 5 In matlab this is achieved with the function buffer. Is

Hello! I do not understand what is meant by: "aic" and "bic" follow a top-down strategy based on the Akaike's and Schwarz's information criteria in the datails to the ADF.test function. What does a "top-down strategy" mean? Probably the respective criterion is minimized and the mode vector contains the lag orders at which the criterion attains it

Hello! I am applying the ADF.test function from package uroot to a time series of data. When I apply the full test, incorporating drift and trend terms, the regressor estimate of the drift term is not significantly different from zero. So I apply the test to a model without drift term, with deterministic trend only. But then I always get the following error:
