Hello, I have problems running the R.matlab package. I work with R 2.3.1, under windows (using the Rgui). It seems that, even after loading the package, the "simple" functions such as writeMat() or readMat() are not recognized. For example, the following script leads to an error: > install.packages("R.matlab") --- Please select a CRAN mirror for use in this session ---

Dear list, I'm trying to understand the graphical parameters by a systematic exploration of the par() function (if you are interested by the result it's here http://pbil.univ-lyon1.fr/R/fichestd/tdr75.pdf, the comments are all in french but it's pure R code under Sweave). I have a problem with par(tmag) illustrated by the following code:

I wanna display some data which there are subsets of a dataframe called "don" but there are errors like this > L=as.numeric(levels(factor(don$Id_Cara))) > for(i in L){ + donC(i)=subset(don, Id_Cara == i, select = c( Id_TrT1, Id_Geno, Id_Rep, Val_O)) + donC(i) + } Erreur dans donC(i) = subset(don, Id_Cara == i, select = c(Id_TrT1, Id_Geno, : impossible de trouver la

Hi everybody, I want to use macro in my R code. But defmacro was not in my libraries. So I installed it : > install.packages("gtools") Installing package(s) into ?C:/Program Files/R/R-2.13.2/library?

Hi all, Running simulations, I'm generating market response to 2 factors X&Y.. There is no closed form for the market response.. The results are store in a matrix Z(X <- seq(.02,.98,.02), Y <- seq(.01,.19,.01)).. For optmization purpose I need to approximate the values for any factor X in 0,02-0,98 and Y in 0,01-0,19 How can I do it ? For one factor : Xn-1 < x <= Xn

I get the following error trying to connect to a MySQL database: > library(RMySQL) Loading required package: DBI > drv<-dbDriver("MySQL") > con<-dbConnect(drv, user="hothand", password=xxx, host="localhost", dbname="hh03"); Error in mysqlNewConnection(drv, ...) : RS-DBI driver: (could not connect hothand at localhost on dbname

Hi all I've a continuous variable and I want to test (graphically, plotting observed and theoretical distr, qqplot) whether it follows some formal distribution. (some thing close to Ricci document : Fitting distributions with R, Feb05). The distribution I want to fit is a truncated Gamma at 1 (the minimal value is 1), P(x)=Pgamma(rate,x)/(1-Pgamma(rate,x<1)) NB : changing the variable

Dear r-helpers, I can't get lsa to run because: > library(lsa) Loading required package: Rstem Error in library(pkg, character.only = TRUE, logical = TRUE, lib.loc = lib.loc) : 'Rstem' is not a valid package -- installed < 2.0.0?

Is it possible for S4 to (continue) dispatch to a class created during dispatching? The code below doesn't work; is this not possible or have I ommitted something? Concept was to create a SEXP with R_AllocatePtr, give it a class attribute, and continue dispatch. Example code below omits multiple parameters that can be different types. Essentially, any parameter would be converted to an

R-helpers, Is there an easy way to call an external (C) program using .C or .Call without including the code in a package. I know how to do it using system(), but that doesn't seem to be a permanent or portable solution. Initially I tried: .Call('filepath.to.c.function', arg1) and got this error: Error in .Call("filepath.to.c.function", "arg1", :

Hi, I am trying to use boot() to refit an ordinal logit (polr in MASS) model. (A very basic bootstrap which samples from the data frame without replacement and updates the model.) I need to extract two statistics per run (the coefficients and zeta) and I tried concatenating them into a single vector after fitting, but I get the following error: Error in "[<-"(*tmp*, r, ,

Hi all, I'm trying to estimate a nested model (purchase decision, cloglog formula, & quantity bought given a purchase, truncated Poisson). Some of the parameters are mixed (6) and 4 are fixed for all the respondent. The simulated ML (500 simulations) method forwards highly correlated estimates. After some research, Hybrid Monte Carlo seems to be a good alternative to estimate the model. I

hi everybody, I noticed the following: in one of my scripts 'layout' is used to generate a (approx. square) grid of variable dimensions (depending on no. of input files). if the no. of subplots (grid cells) becomes moderately large (say > 9) I use a construct like ###layout grid computation and set up occurs here### ... opar <- par(no.readonly = T);

I have a number simple R functions written for the biologists I work with. These functions will evolve, and the documentation will get steadily better. I hope to put them in a package on a local webserver, along with lots of help files, so that the users can easily update their installation. The functions are pure R, with no compiled code, but alias, I cannot figure out how to build this

I have been running R CMD check for the first time on of our own packages, which otherwise builds, installs and runs just fine. The package depends on package akima and suggests package multtest; suggesting multtest is indicated because a) it loads a lot of other Bioconductor packages, very slowly, and b) it is only needed for one specific subroutine, which executes require(multtest)

Hi, I'm trying to add points to 2 plots on the fly using par(mfg=vector) so switch between them. However, the appropriate scales aren't switched when changing from one plot to another, e.g. par(mfcol=c(2,1)) plot(1,1, col="blue") # blue plot plot(1.2,1.2, col="red") # red plot points(1.1,1.1) # appears to bottom left of red point par(mfg=c(1,1)) #
