similar to: print.raw - but convert ASCII?

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

Hello r-devel, The attached Code page 437-encoded file contains 245 characters (including the final newline), but readLines only reads 242 of them: > test_text <- readLines(file('437__characters.txt', encoding='437')) Warning message: In readLines(file("437__characters.txt", : incomplete final line found on '437__characters.txt' > test_text [1]

Hello! I am producing a set of images and I would like them to be sorted by names I give. I was able to produce my names and add integer to them. That is easy. But my problem lies in sort of file from this process: figure_10.png figure_11.png figure_12.png ... figure_1.png figure_20.png ... So I would like to convert integers to something like 01 if upper limit for this conert is 10 or 001

We''re starting to grow our ZFS environment and really need to start standardizing our monitoring procedures. OS tools are great for spot troubleshooting and sar can be used for some trending, but we''d really like to tie this into an SNMP based system that can generate graphs for us (via RRD or other). Whether or not we do this via our standard enterprise monitoring tool or

Dear R-Users, I need a very fast and reliable database solution so I try to serialize a data.frame (to binary data) and to store this data to an SQLite database. This is what I tried to do: library(RSQLite) con <- dbDriver("SQLite") db <- dbConnect(con, "test") dbSendQuery(db, 'CREATE TABLE frames("simID" INT, "data" BLOB)') data.bin <-

I'm running Dovecot as proxy in front of some IMAP/POP3 Dovecot & Courier-IMAP servers and in the last couple of days I've been seeing a lot of imap-login crashes (signal 11) on both 2.2.18 and 2.2.25, all SSL related. The following backtraces are taken running 2.2.25, built from source on a test system similar to the live proxy servers. OS: CentOS 6.8 64bit Packages:

Hi, right now we have (on R v2.7.0 patched (2008-04-23 r45466)) that: > rawToChar(raw(0)) [1] "" > rawToChar(raw(0), multiple=TRUE) character(0) Is this intended or should both return character(0)? Personally, I would prefer that an empty input vector returns an empty output vector. Same should then apply to charToRaw(), but right now we get: > x <- character(0) >

Dear List, I have a list of 600+ *.gz files that I would like to extract and read the geotiffs contained within them. I tried using the untar() function to simplify this task but I am stumped by an error. I've combed the Internet for a solution without luck. The details are below, and any help in solving this matter is appreciated. > files = list.files(path = "J:/GIMMS/NDVI",

Hi All, I have a really strange issue occuring where if I run "show dialplan" or "dialplan show" or "dialplan show parkedcalls", then asterisk dumps core. It only appears to happen with contexts that are created within res_features. I am able to display all my other dialplans, but, every time I try to just do a normal "dialplan show" asterisk core dumps

Hello All, I have managed to get my cisco and asterisk able to talk to one another I think. But cannot make a call from a phone behind call manager to the asterisk server. I have followed the cisco asterisk integration on the wiki. I have also setup a number 3000 for dialing for current local time and date on asterisk. I can call from a sip phone behind asterisk, no problems. The problem

Hello, I would like to compress a long string (character vector), store the compressed string in the text field of a SQLite database (using RSQLite), and then load the text back into memory and decompress it back into the the original string. My character vector can be compressed considerably using standard gzip/bzip2 compression. In theory it should be much faster for me to compress/decompress

Hi, ?rawToChar 'rawToChar' converts raw bytes either to a single character string or a character vector of single bytes. (Note that a single character string could contain embedded nuls.) Allowing embedded nuls in a string might be an interesting experiment but it seems to cause some troubles to most of the string manipulation functions. A string with an embedded 0:

Hi, A piece of my code that uses readBin() to read a certain file type is behaving strangely with R 2.7.0. This seems to be because of a failure to match() strings after using rawToChar() when the original was terminated with a "\0" character. Direct equality testing with == still works as expected. I can reproduce this as follows: > x <- "foo" > y <-

I know that there is a function to convert binary data to string named rawToChar.but I wander is there any similar function for "Integer" and "float".I need to read some binary file in "integer" and "float" data. I can do this job in this way: (as below) first convert 4 byte raw to bits then pack bits back to "integer", but it not work for

Hi, I'm running into more issues when reading data from a gzfile connection. If I read the data sequentially with successive calls to readBin(), the data I get looks ok. But if I call seek() between the successive calls to readBin(), I get corrupted data. Here is a (hopefully) reproducible example. See my sessionInfo() at the end (I'm not on Windows, where, according to the man page,
