Generally you'd use file() to open the file, then use readLines(), say inside a while() loop to read one `chunk' at a time. However, your example looks a bit strange. The possibility of empty line makes it a bit more complicated, by that last couple of lines seems to suggest that you could have a line of data follow by another line of data without variable label. If that's true, I

ComRades, How do you put a superscript on a scalable delimiter? I want to put 'b' as the power of the expression in the following plot: t <- 1:25 K <- 0.2 y <- ((1-exp(-K*t))/(1-exp(-K*t)*exp(K)))^3 plot(t,y,"l",main="K=0.2, b=3") text(15,5,expression(bgroup("(",frac(1-e^-Kt,1-e^-Kt*e^K),")"))) Plotmath examples in demo(plotmath) do not

ComRades, On a recent Windows XP system that I have to use at work, I installed Tinn-R 2.3.4.4 and R 2.10.1 When I mark-select a piece of code, say summary(x) written in Tinn-R and send it to the RGui using the send button, the RGui console instead of showing me my piece of code, it shows something like source(.trPaths[5], echo=FALSE, max.deparse.length=150) The code is executed fine but if

Dear all, I need to re-define some mathematical operators (+, *, /, etc) for an S4 class based on array. All references I have found (S Programming, Green Book) show how to define S3 methods for this (like in page 89 of S Programming for "-.polynomial"). What is the preferred S4 way for doing this? I hope I haven't missed some obvious piece of documentation. Many thanks, Iago

Hello, In my Debian 3.0 systems, packages are installed in two different places, namely /usr/lib/R/library and /usr/local/lib/R/site-library, depending on whether they come from debian packages or CRAN ones. Help pages for my own packages, installed in the second location, cannot find help pages from, for example, the base package via \link{}. I also tried specifying the package with

Hi everybody, I am working with gams and I have found some questions when plotting gams models. I am using mgcv, and my model looks something like this: model<- gam(x ~ s(lat,long)) I can plot the output of the model using plot(model) or plot.gam(model) and I get a surface plot. That is ok, but what I want to do now is to extract the data used to perform the surface plot. Like that I

Hello, I am about to move all of my modelling work into R, and I have been investigating the present state of MCMC and Bayesian methods in R. Following a thread on the mailing list in 2000, I have looked at mcmcpack and Hydra. Three years down the line, is there anything new in this area? I have used both MCSim and WinBUGS in the past. The first one seems promising, but is too focused towards

*Hello all ** I am a newbie to R plotting maps. I am trying to plot over a world map a layer of Biogeochemical provinces (BGCP) by A.R. Longhurst. Each ocean region unfortunately are quite irregular in shape (not perfect squares). In GIS this layer of ocean provinces would be a layer of polygons, which I am assuming it cannot be plotted with R. I was wondering If anybody has encounter this

Hi, I'm trying to get a package to pass through "R CMD check --as-cran" and have run into a problem that gives me no idea where to look to fix it.

Hello, I want to compute a correlation test but I do not want to use the degrees of freedom that are calculated by default but I want to set a particular number of degrees of freedom. I looked in the manual, different other functions but I did not found how to do it Thanks in advance for your answers Yours Florence Dufour PhD Student AZTI Tecnalia - Spain

You could calculate the confidence interval of the correlation at your desired df: http://davidmlane.com/hyperstat/B8544.html The below code takes as arguments the observed correlation, N, and alpha, calculates the confidence interval and checks whether this includes 0. cor.test2=function(r,n,a=.05){ phi=function(x){ log((1+x)/(1-x))/2 } inv.phi=function(x){

Hi, A lowess method is defined in our package for one of our S4 classes. To explicitely define the generic this is being used if (!isGeneric("lowess")) setGeneric("lowess", useAsDefault = lowess) This works fine for many other methods inherited from various R packages. In this case a warning is issued in R CMD check: * checking R code for possible problems ... NOTE
