Hi there, any explanation for this? > intToUtf8(66) Error in intToUtf8(66) : argument 'x' must be an integer vector > intToUtf8(c(66,55)) Error in intToUtf8(c(66, 55)) : argument 'x' must be an integer vector > intToUtf8(c(66,55),multiple=TRUE) Error in intToUtf8(c(66, 55)) : argument 'x' must be an integer vector...

...to come to a stop using SUSE + WINE. Is it possible to run that lot on top of valgrind? Of course, it will probably take all day ... If not, I have a clue which might help. The problem seems to lie in the "sub" routine. In the original report I used -- cut here -- gctorture() u <- intToUtf8(c(rep(1e3,1e2),32,c(rep(1e3,1e2)))) v <- rep(u,1e2) v <- sub(" ","",v) v %in% "" -- cut here -- I've tried reducing this a bit more. Replacing intToUtf8 with a direct assignment writing out the string with Unicode escapes seems to make no difference. The %...

Dear Professor Ripley, a. I apologise for not including the file. I sent the E-Mail to=20 R-bugs at r-project.org with an attachment, but the attachment evidently got=20 lost. However the text of the file is as follows: --- CUT HERE ---- gctorture() characters <- intToUtf8(200:300) indices <- rep(sequence(5),10) substrings <- substring(characters,indices,indices + 5) factor(substrings) --- CUT HERE --- b. There is no Unicode file involved, the Unicode comes from the=20 "intToUtf8" function. c. The operating system is Windows XP Professional (2002), S...

Dear R-helpers, I want to append a Ctrl-M character to a string and then save it to a text file. mystring<-"This is a test." # How do I add a Ctrl-M to it in the end ?? cat(mystring,file="testfile") Many thanks, Ashim [[alternative HTML version deleted]]

As per `?intToUtf8`, and in the comments to `valid_utf8`[1], R intends to prevent illegal UTF-8 such as UTF-8 encoded UTF-16 surrogate pairs.? `R_nchar`, invoked via `base::nchar`, explicitly validates UTF-8 strings[2], but allows the surrogate: ??? > Encoding('\ud800') ??? [1] "UTF-8" ??? >...

Hi all, I have a csv file containing words with *UNPRINTABLE ASCII* characters (described in the following table). Are there any viable method in eliminating these characters? I realise that *EXTENDED ASCII* characters (i.e , ¡, ¢, £, ¤ etc) can be removed or replaced via *"gsub"* or *"gregexpr"* functions. But am not certain with the *UNPRINTABLE ASCII* characters. Your

Hi all, In Spanish vowels with accent like ?, ?, ... doesn't affect to the alphabetical order of vector of strings. I mean, a or ? don't matter for establishing the alphabetical order.
