Dear Martin, Does the work on nchar mean that bugs #16090 and #16091 will be resolved [1,2]?

Remember that nchar() returns by default the number of *bytes* and not the number of characters. I've recently spotted many cases in which nchar() has been used with substr() which works in characters; this can lead to incorrect results. (This seems the commonest use of nchar() in packages.) There were two reasons why nchar() was left defaulting to bytes when we allowed MBCSs in R:

Dear all I'm a bit surprised by the results output from nzchar(). The help page says: "nzchar is a fast way to find out if elements of a character vector are *non-empty strings*." (my emphasis. However, if you do > x <- c(letters, NA, '') > nzchar(x) [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE [13] TRUE TRUE TRUE TRUE TRUE TRUE

Full_Name: Nick Efthymiou Version: R1.5.0 and above OS: Red Hat Linux Submission from: (NULL) (162.93.14.73) With the introduction of the functions rowSums(), colSums(), rowMeans() and colMeans() in R1.5.0, function "SEXP do_colsum(SEXP call, SEXP op, SEXP args, SEXP rho)" was added to perform the fast summations. We have an excellent opportunity to improve the accuracy by

The deparse options used by default by 'deparse' and 'dput' are c("keepNA", "keepInteger", "niceNames", "showAttributes") but Defn.h still has #define DEFAULTDEPARSE 1089 /* KEEPINTEGER | KEEPNA | NICE_NAMES, used for calls */ i.e., with the SHOWATTRIBUTES bit turned off. Is that on purpose? Note that this leads to weird

What other packages do you have loaded? Perhaps a BioConductor one that loads S4Vectors that announces upon load: Creating a generic function for 'nchar' from package 'base' in package 'S4Vectors' Maybe a red herring... ~Malcolm > -----Original Message----- > From: R-devel [mailto:r-devel-bounces at r-project.org] On Behalf Of Duncan > Murdoch > Sent:

Hi, Is nchar function knowingly slow in R? I'm doing some string formatting that requires multiple call to nchar, and nchar seems to be very slow. Experiment 1, pass nchar inside sprintf, and it takes 0.7 seconds > system.time(for (i in 1:10000) + str = sprintf('0005%020d', nchar(op)) + )[3] [1] 0.7 Experiment 2, get the length of op separately using nchar, and then pass

In R 2.9.1 Windows: > nchar(factor(paste('sdf',1:10))) [1] 1 1 1 1 1 1 1 1 2 1 so it appears that nchar is counting the number of characters in the numeric representation, just like: > nchar(as.numeric(factor(paste('sdf',1:10)))) [1] 1 1 1 1 1 1 1 1 2 1 but ?nchar says explicitly: x: character vector, or a vector to be coerced to a character vector.

Dear list, If I include the zero-width non-breaking space (\ufeff) in a string, nchar seems to compute the wrong number of columns used by 'cat'. > x <- "f\ufeffoo" > x [1] "f?oo" > nchar(x,type="width") [1] 2 I would expect "3" here. Going through the documentation of 'Encoding' and 'encodeString', I don't think

In trying to change the driver used by Sweave on the command line using R CMD Sweave --driver=foo I consistently get the "directory 'foo' does not exist' error. (For any value of 'foo', even the default 'RweaveLatex'.) Looking up the source code for function .Sweave that is called by 'R CMD Sweave', I notice that the argument 'driver', if

Hi all, I have a puzzling problem related to nchar. In R 3.2.1, the internal nchar gained an extra argument (see https://stat.ethz.ch/pipermail/r-announce/2015/000586.html) I've been testing code using the package copula, and at home I'm still running R 3.2.0 (I know, I know...). When trying the following code, I got an error: > library(copula) > fgmCopula(0.8) Error in
