While building/checking a package of mine that depends on glmnet, I got the following message: * checking whether the name space can be loaded with stated dependencies ...Warn ing: running command ''"C:/Users/nisabbe/Documents/R/R-2.13.1/bin/i386/Rterm.exe" R_DEFAULT_PACKAGES=NULL --vanilla --slave -f C:\Users\nisabbe\AppData\Local\Tem p\RtmpZpjj07\Rin121ae93''

Dear all, I've recently had some issues getting my package to successfully "check". This was on R-Forge, so it's not obvious for me to provide SessionInfo or the likes (if necessary, Stefan can chime in?). After some research (mainly by Stefan Theussler, driving force behind R-Forge), this turned out to be the root cause: On R-Forge, the version of R installed was the

Hello list. This is from an R session (admittedly, I''m still using R 2.11.1): > print function (x, ...) UseMethod("print") <environment: namespace:base> > showMethods("print") Function "print": <not a generic function> Don''t the two results contradict each other? Or do I have a terrible misunderstanding of what

Hello list. Another 'puzzle' for which I don't have a clean solution. Say I have a multidimensional object, e.g.: Mm<-matrix(1:6, nrow=2, dimnames=list(c("a","b"), c("g","h","i"))) And on the other hand I have a list Ind<-list("b","g") This holds, for each dimension, an indexer for that dimension. Now I would

Hello list. For some reason, the makers of glmnet do not accept a dataframe as input. They expect the input to be a matrix, where the dummies are already precoded. Now I have created a sample dataset with . 11 factor columns with two levels . 4 factor columns with three levels . 135 continuous columns (from a standard normal) . 100 observations (rows) Say this dataframe is in dfrPredictors. What

Dear list, I''ve had this a few times now, and wonder if this is possible: I''m using a package, often for plotting something, but I want to tune the way the plotting goes, in a way that was not foreseen by the maker of the package. Now, most of the time, these kinds of R functions (say pkg::plot.something) call into other R functions (say pkg::plot.something.internal), and

This problem is likely to be specific to Windows, and particularly Win7. After a successful build of a package (R CMD build addendum), I immediately run an R CMD check for the same package. Not always, but _very_ often, I get the following error: C:\Users\nisabbe\Documents\@Doctoraat\R>R CMD check addendum Loading required package: tcltk Loading Tcl/Tk interface ... done Loading

Hi All. I often find myself in this situation: . Based on some vector (or list) of values, I need to calculate a few new values for each of them, where some of the new values are numbers, but some are more of descriptive nature (so: character strings) . So I use e.g. sapply, passing a custom function that returns a list with all the calculated values . The result of

Hi R people. I ran into this problem: I created a plot with errbars, like this: > errbar(x=c(1,2,3,4), y=c(2,1,3,3), yminus=c(1.5,0.5,2.5,2.5), yplus=c(2.5,1.5,3.5,3.5)) Next, I wanted to accentuate some x value with an abline, like this: > abline(v=2) In one of my R sessions (which admittedly I have had open for quite a while now), the abline draws outside of the plotting region

Hello all. I'm developing a package for R holding a Gibbs sampler, which tends to have better performance when written in C than in R. During each iteration in the Gibbs sampler, I need the inverse of a symmetric matrix. For this, I wish to use lapack, as is concisely suggested in "Writing R extensions", since this will have better performance than I could ever write myself. After

Hi All,  I have been trying to use glmnet package to do LASSO linear regression. my x data is a matrix n_row by n_col and y is a vector of size n_row corresponding to the vector data. The number of n_col is much more larger than the number of n_row. I do the following: fits = glmnet(x, y, family="multinomial")I have been following this

Hi Everybody! I must start with a declaration that I am a sparse user of R. I am creating a credit scorecard using a dataset which has a variable depicting actual credit history (good/bad) and 41 other variables of yes/no type. The procedure I am asked to follow is to use a penalized logistic procedure for variable selection. I have located the package "glmnet" which gives the complete

Hello list. I feel like an idiot. There exists a method called expand.grid which, from the documentation, appears to do just what I want, but then it doesn''t, and I can''t get it to behave. Given a dataframe dfr<-data.frame(c1=c("a", "b", NA, "a", "a"), c2=c("d", NA, "d", "e", "e"),

Hi, I am trying to do logistic regression for data of 104 patients, which have one outcome (yes or no) and 15 variables (9 categorical factors [yes or no] and 6 continuous variables). Number of yes outcome is 25. Twenty-five events and 15 variables mean events per variable is much less than 10. Therefore, I tried to analyze the data with penalized regression method. I would like please some of the

Hi all. I'll start by introducing the origin of the problem, although it appears to me that it goes beyond my specific setting. I'm currently working on a method for finding the 'lowest named function call' on the call stack. I am aware that the name of a function is not uniquely defined, but for most reasonable cases, the intended name can be easily induced. You can see some of

Hi all. I am currently attempting to build a list of sparse matrixes. That I have already achieved, by > vmat <- list() > for (i in 1:n) { > vmat <- c(vmat, sparseMatrix(i,j,x=data) > } How I am trying to select those elements from the list where the column e.g. 999 is not null. I can do this for one of the sparse matrices with > which(vmat[[1]][,999] != 0) which

Folks, I have a 'matching' matrix between variables A, X, L, O: > a <- structure(c(1, 0.41, 0.58, 0.75, 0.41, 1, 0.6, 0.86, 0.58, 0.6, 1, 0.83, 0.75, 0.86, 0.83, 1), .Dim = c(4L, 4L), .Dimnames = list( c("A", "X", "L", "O"), c("A", "X", "L", "O"))) > a A X L O A 1.00 0.41

Hi there, Could someone help me with the following programming problem..? I have written a function that works for my intended purpose, but it is quite closely tied to a particular dataframe and the names of the variables in this dataframe. However, I'd like to use the same function for different dataframes and variables. My problem is that I'm not quite sure how to tell my function in

How can achieve this in R using seq, or rep function c(-1,0,1,0,-1,0,1,0,-1,0) The range value is between-1 and 1, and I want it such that there could be n number of points between -1 and 1 Anyone? Please help Thanks Rusty [[alternative HTML version deleted]]

Hi R helpers, I am trying to use the if statement to generate a truncated random variable as follows: if (y[i]==0) { v[i] ~ rnorm(1,0,1) | (-inf ,0) } if (y[i]==1) { v[i] ~ rnorm(1,0,1) | (0, inf) } I guess I cannot use " | ( , ) " to restrict the range of a variable in R. Could you let me know how to write the code correctly in R? Many thanks for your help. Maomao [[alternative
