I'm using R 2.11.1 on Win XP (32-bit) with 3 GB of RAM. My data has (only) 16.0 MB. I want to create a VCorpus object using the Corpus function in the tm package but I'm running into Memory allocation issues: "Error: cannot allocate vector of size 372 Kb". My data is stored in a csv file which I've imported with "read.csv" and then used the following to create

Dear users, I'm working on binary classification problem using Support Vector Machines (SVM). My objective is to train a series of SVM models on a grid of hyperparameters and then select those that maximize the AUC based on an independent validation sample. My attempted code is shown below. It runs well on "small" data sets but when I use it on a slightly larger sample (e.g., my

Dear List, I'm trying to create a formula method, allowing for a "special" character in the formula (i.e., similar to for example the gam package with the character "s" in y ~ s(x)). I've checked and it seems this is done through attr(,"specials"). However, the section of code below (as an example extracted from the gam package) gives me an error as shown at

Hi, All I have a data frame as follows: > attach(mf) > names(mf) [1] "centre" "complex" "appl" "pool" "month" "alloc_gb" I want to summarize this as follows: agg<-summarize(alloc_gb,by=llist(centre,complex,appl,month),FUN=sum, na.rm=TRUE) That seems to run fine but there something odd about the output. The

Hi, All I have a data frame like this. > names(x) [1] "month" "alloc_gb" One of the columns contains the dates I want to use: > data.class(x$month) [1] "yearmon" I would like to make a time series object out of this. However the ts function seems to require me to spell out the starting date. Is there a way to tell ts to use the date column I already

Hi, All I have a data frame as follows: > data.class(tapes) [1] "data.frame" > names(tapes) [1] "date" "loc" "class" "drp" "data" "scratch" "reclaim" "total" Date is a date; loc, class and drp are factors; the rest are numerics. I want to generate separate plots by date for the

Is there an easy way to compile a packages's fortran so that it has the information for ddd or gdb to follow the lines of the code? I seem to remember seeing something about this, but I cannot find it in Writing R Extensions. (I see about Valgrind, debugging a segfault, and some other tricks, but what I really want is to follow the fortran logic.) Thanks for any pointers, Paul

I am trying to extend an S3 method to work with an S4 object as well as the S3 objects it works with, but UseMethod does not seem to recognize the S4 class and dispatches to the default method. Is this to be expected or should I be looking for an error in my code? If it is not an error in my code, is there an easy way to do this, or do I have to convert the generic to S4 and then make those

In one package (pk1) I define some S3 generics and methods. In pk2 I extend the methods to some S4 objects following the description in ?Methods, with setMethod() and setGeneric() either explicit or implicit (tried both). I export the S3 generic and methods from pk1 NAMESPACE and the S4 from pk2. This works, except when I try to use a function defined in pk1, Within the function the S4 method

I am experimenting with putting vignettes in a vignettes/ directory as suggested in the new R release news. If I understand correctly, it is now suggested that the vignette source (.Stex in my case) should be in the vignettes/ directory and the pdf should be put in the inst/doc/ directory, for the case when it is not being built by R CMD build. I am getting an error (R-2.14.0): (cd inst/doc ;

Is it possible in R to call a fortran routine that sets variables in a common block and expect the values to persist when a call is made from R to a second routine that uses the common block? If not (as I suspect), is it possible to use a common block in a group of routines that are used together, for as long the routines do not return to R? Paul

I am trying to understand the missing vs default value for an argument to an S4 method. (I'm not sure if this is a bug or my confusion.) In S3 I can specify a default value for an argument and then both check if the argument was missing in the call, and use it because it takes on the default value. I do not seem to be able to do that in S4 as shown by this simplified example:
