similar to: RW 0.64.2 substring() string truncation?

Full_Name: Naoki Takebayashi Version: 0.65.1 OS: Linux/Alpha Submission from: (NULL) (129.79.224.171) When I was reading a file with read.table("junk.data"), it seg-faulted. I found out that it seg-faulted when the last line of data file didn't have the newline char. For example, file like this: 23 3 31 2 24 1<EOF> Here is a fix. --- R-0.65.1/src/main/scan.c.orig

Hi, Note that one significant change to read.dcf() that happened since R 3.0.2 is the addition of support for arbitrary long lines (commit 63281), which never worked: dcf <- paste(c("aa: ", rep(letters, length.out=10000)), collapse="") writeLines(dcf, "test.dcf") nchar(read.dcf("test.dcf")) # aa # [1,] 8186 The culprit being line

I was hit by ugly crashes of R, when I tried to read big data sets ("volcano"). So I looked into the code and found the following in character.c (triggered by substr()): I assume that the helper function AllocBuffer() shall facilitate an economic memory management. But the use of realloc() in the else-branch does not conform to ANSI and may hit you with certain compilers. When called

In R's sprintf() if any of the arguments has length 0 the function aborts. E.g., > sprintf("%d", integer(0)) Error in sprintf("%d", integer(0)) : zero-length argument > sprintf(character(), integer(0)) Error in sprintf(character(), integer(0)) : 'fmt' is not a non-empty character vector This comes up in code like x[nchar(x)==0] <-

Hello together, i have a question for "substring". I know i can filter a number like this one: bill$No<-substring(bill$Customer,2,4) in this case i get the 2nd, 3rd and 4th number of my Customer ID. But how can i do this, if i want the 2nd, 3rd and 4th number of a column. Like this one. I have: Mercedes_02352 Audi_03555 and now i want to filter this data.frame to 235 355 can you

Hi all, I'm getting the following error from substring: > substr("<I>Jens Oehlschl\xe4gel-Akiyoshi", 1, 100) Error in substr("<I>Jens Oehlschl\xe4gel-Akiyoshi", 1, 100) : invalid multibyte string at '<e4>gel-A<6b>iyoshi' Is that normal / intended? I've tried setting the Encoding/locale to Latin-1/UTF-8 but that does not help. nchar

Dear R People: Here is a toy example: > x <- c("2E","5W","12H") > substr(x,2,2) [1] "E" "W" "2" > Sometimes x has 3 elements, sometimes 2. I want to extract the last element, and then extract the other 1 or 2 elements. How can I do this, please? TIA, Sincerely, Erin -- Erin Hodgess Associate Professor Department of

Hi, I have an Ubuntu 8.04 box running as Samba PDC (version 3.0.28a) with an LDAP backend, and I tried to migrate a share from a Win2003 server to the Samba box. However, running the "migrate shares" or the "migrate files" commands always results in errors: $ net rpc share MIGRATE SHARES data_share -S w2k3box -U <admin> --destination=localhost migrating:

Dear R People: I am trying to split a character vector into a set of individual letters: Ideal: x3 <- c("dog") "d" "o" "g" I tried the following: > strsplit(x3) Error in strsplit(x3) : argument "split" is missing, with no default > strsplit(x3,1) [[1]] [1] "dog" I know that this is incredibly simple, but what am I doing

Here's my translation of the Fibonacci example into OCaml: open Printf open Llvm let build_fib m = let fibf = define_function "fib" (function_type i32_type [| i32_type |]) m in let bb = builder_at_end (entry_block fibf) in let one = const_int i32_type 1 and two = const_int i32_type 2 in let argx = param fibf 0 in set_value_name "AnArg" argx; let

In what way is this a bug in R? It looks like a bug in the package, and as Defn.h is not part of R's API any packge using it is `at risk' (and cannot be installed in a binary-only installation, or even an installed version of R). In particular, Defn,.h depends on config.h, and it seems you installed a binary version of R and used separate sources. I would suggest building R from

How to substring the following vector (in data frame b) >b a 11 12 1234 1245 124567 126786 145769 such that: a1??? a2 1???? 1 1???? 2 12??? 23 12??? 34 124?? 567 126???787 145???769 ? I tried logical commands with substr() did not work out.

Thanks for the quick response Ivan. readLines with encoding='latin1' works for me (on Ubuntu). However I was more concerned with the inconsistency in results between substr and regexpr. I was expecting that if one of them errors because of an unknown encoding then the other should as well. Even better, if regexpr works, why shouldn't substr work as well? Incidentally the analogous

Hello, I would like to have a function that retrieve matching strings in the same way as with java.util.regex (java 1.4.2). Example: f('^.*(xx?)\\.([0-9]*)$','abcxx.785') => c('xx','785') First of all: Is it possible to achiev this with grep(... perl=TRUE,value=TRUE )? As I would call this function very often with large data, I'm reluctant to use Sjava

Dear list, Tadashi Kadowaki has developed a pdf device package that allows to add hyperlinks and popups to (currently) text, mtext and rect calls. The package passes R CMD check (minor warnings) and compiles on MacOS X and GNU/Linux, but we do not succeed in building the package for Windows. The current version of the package can be checked out as svn checkout

Here's an update: I checked the ChangeLog for R, and it seems like readDCF was changed in 3.0.2. I went on a whim and copied src/main/dcf.c from R 2.15.3 over to 3.2.2, and R compiled fine and install.packages now work for me. This is probably not ideal, but it at least makes R usable on AIX for me. Would definitely like to help figure out what's wrong with the new dcf.c on AIX.

Help pages for stop/warning reference the option "warning.length", e.g. from ?stop: Errors will be truncated to getOption("warning.length") characters, default > 1000. Essentially the same is in ?warning. Neither of these mention the hard-coded limits on the acceptable values of this option in options.c
