Dear All, I assume this is an R-devel issue, apologies if I missed something obvious. I have a dataframe where the row names are country codes, based on ISO 3166, something like this: ------------ "v1" "v2" "UK" 1 2 "NA" 2 3 ------------ It happens that "NA" is the country code for "Namibia", and that creates problems on

Dear r-devel, I am trying to automatically check if two successive versions of a package have the same results (i.e. code not broken), by parsing the example sections for each function against a previously tested version. While trying to replicate the code from example(), I am facing an error related with te "index.search" function (line 7 in the example() code). This is the code I am

Dear R devel, Apologies for these (most probably trivial) questions, doing my first attempt to call C from R (and actually learning C in the process). I need to pass a matrix to C, and after reading R-exts.pdf (many times), I was unable to find how to handle matrices at C-level... except for, what probably is the answer, that matrices are in fact vectors with dimensions. This is a sample code I

Dear R-devel, I am now at a debugging phase, and would like to inspect the (individual) values in an arbitrary R vector. It should be simple, but after hours of reading I am simply unable to find the right information. A possible C code is: ????????????????? # include <R.h> # include <Rinternals.h> # include <R_ext/Rdynload.h> SEXP foo(SEXP x) // where x is a vector passed by

Hi again, I was contemplating the solution using base 3: set.seed(3) mat2 <- matrix(sample(0:2, 15, replace=T), 5, 3) Extracting the line numbers is simple: bases <- c(3, 3, 3)^(2:0) # or just 3^(2:0) colSums(apply(mat2, 1, function(x) x*bases)) + 1 [1] 7 23 25 8 1 The problem is sometimes the columns have different number of levels, as in: mat1 <- expand.grid(0:2, 0:2,

Dear all, I'd like to produce a simple pie chart for a customer (I know it's bad but they insist), and I have some difficulties setting the initial angle. For example: pie(c(60, 40), init.angle=14) and pie(c(80, 20), init.angle=338) both present the slices in the same direction, where: pie(c(60, 40)) pie(c(80, 20)) present the slices in different directions. I read everything I

Dear devels, I need to create a (short) vector in C, which contains potentially very large numbers, exponentially to the powers of 2. This is my test example: lgth = 35; int power[lgth]; power[lgth - 1] = 1; for (j = 1; j < lgth; j++) { power[lgth - j - 1] = 2*power[lgth - j]; } Everything works ok until it reaches the limit of 2^32: power: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024,

Dear list, On a follow up from my previous email, I am now trying to allocate vectors of length larger than 32-bit in C. >From the R internals documentation, I read that: "The sxpinfo header is defined as a 32-bit C structure..." and "A SEXPREC is a C structure containing the 32-bit header..." The question is: does the INTSXP allow vectors larger than 32-bit? A test

Dear all, This is probably a stupid question for which I have a solution, which unfortunately is not as straighforward as I'd like. I wonder if there's a simple way to apply a weighting variable for the cases of a dataframe (well I'm sure there is, I just cannot find it). My toy example: > my.data <- data.frame(var1=c("c", "e", "a",

Dear R-list, Could anybody tell me where to find information about changing the measurement unit from inch to centimeters? I read the help from X11, I read R-intro and I did some searhing in the R archives, but I couldn't find the answer. For example, I would like to produce a plot of a certain width and height: X11(width=10, height=5) and I would like these to be centimeters, rather

Dear all, There is something I'm missing in order to understand the following behavior: > aa <- c("test", "name") > ifelse(any(nchar(aa) < 3), aa[-which(nchar(aa) < 3)], aa) [1] "test" > any(nchar(aa) < 3) [1] FALSE Shouldn't the ifelse function return the whole aa vector? Using if and else separately, I get the correct result... >

Dear all, Some very wise data entry person gave me about an hour of a headache, trying to find out why a 2000x500 dataframe won't be read into R. After much trial and error, I pinpointed the problem to an accidentally inserted double quote into a string variable (some comments from an open question). This can be replicated by: aa <- data.frame(id=1:2, var1=c("some \"

Dear all, I am trying to import a SAS file into R (in fact I only need the value labels from the formats file), using Hmisc package, but I get this error: my.sas <- sas.get("/home/adi/3", "fis1_sgg") sh: sas: not found Error in sas.get("/home/adi/3", "fis1_sgg") : SAS job failed with status 32512 I read some past discussions and I get the impression

Dear list, This should be a simple one, I just cannot see it. I need to generate a sequence of the form: 4 5 6 13 14 15 22 23 24 That is: starting with 4, make a 3 numbers sequence, jump 6, then another 3 and so on. I can create a whole vector with: myvec <- rep(rep(c(F, T, F), rep(3, 3)), 3) Then see which are TRUE: which(myvec) [1] 4 5 6 13 14 15 22 23 24 I'd like to avoid

Dear All, QCA package version 1.0-4 has been released today, the sources are now visible on CRAN and the binaries for Windows and MacOS should appear in a couple of more days. We highly recommend upgrading to this version. Apart from a number of small bug fixes, the most notable reason to upgrade is a dramatic increase in speed, due to the compilation of some computationally intensive parts of

Dear R-devel, I am trying to do something similar to dynamic length lists in R, but at C level. In R, that would be rather trivial: - determine the length of the list - create the list object - store the values for each component - access value components by using "[[" At C level, for a single component where I need to store a vector of length 5, I do: int *p_result; SEXP my_list =

Hi, A new version of the QCA package (0.6-0) was submitted to CRAN. This is a major improvement, now working with multi-valued data (previous versions accepted binary data only). The "classical" function qmcc() still accepts only binary data, but the enhanced function eqmcc() is now ready for mvQCA. The QCA package performs the Quine-McCluskey algorithm for Qualitative Comparative

Dear All, I have just uploaded a new version of the QCA (Qualitative Comparative Analysis) on CRAN, and it will be propagated in a couple of days. This is version 1.0-0 ("Easter edition") of the package, straight from the previous version 0.6-5, and it represent a major re-write of the package in order to accomodate fuzzy-sets. I am pleased to welcome Alrik Thiem as a co-author of this
