Controlling widths in write.fwf()
Is there a way to handle the widths of values being written to a file using wrtite.fwf() ? For example, I used read.fwf(file, width.vector) to read a file. After making the necessary data manipulation, I want to write the data to a new file in the same width.vector format. Is there a way to specify this? Thanks in Advance Aparna [[alternative HTML version deleted]]

printing tabular data nicely
Hi R-heplers, I would like to print various matrices, dataframes, tables, etc to files, preferably nicely formatted postscript for import into papers. Is there a way to do this? I know ?cat, ?writeLines, ?format, ?paste. But I am not sure of a good combination of these in order to get a nice looking table of information. Any ideas? I guess I want (almost) publication ready output, just like you get for "plot"... (I *don't* want to print to the console, btw) Thx again. W

Summary: How to represent pure linefeeds chr(10) under R for Windows
...to use "binary" connection mode (will not replace \n by \r\n) and explicit specification of line ending as "\r\n". Testing with these gave the following results: ## write.table / read.table: a bit inconsistent: need text connection to read and binary connection to write ## writeLines / readLines: readLines misses a sep= parameter to properly read in such data ## writeChar / readChar: OK Thanks again and Best regards Jens Oehlsch?gel ## Details filename <- "c:/tmp/c2.csv" ## write.table / read.table: a bit inconsistent: need binary conn...

use expression() in a loop

A unique 'click to call' project - Could use some advice
Hello List, I work for an IP communication provider in upstate NY as the engineer assisting our technical support team. We provide a number of different Telco systems to residential subscribers; and in an effort to more effectively trouble shoot termination problems I came up with the idea of creating a click to call system that will allow our agents to effortlessly place test calls.

use of UTF-8 \uxxxx escape sequences in function arguments
While preparing a function that contained non-ASCII characters for inclusion into a package, I replaced all non-ASCII characters with UTF-8 escape sequences (using \uxxxx) in order to make the package portable (and adhere to "R CMD check"). What I didn't expect: when one uses UTF-8 escape sequences in function arguments, one needs to use UTF-8 escape sequences when calling the

write.csv covert Åland to <c5>land
You don't say, but I'd guess you're using Windows. In your code page, the character ? is probably not representable. At some point in the sequence of operations involved in printing the dataframe R puts the string into the native encoding, and since that's impossible on your system, it substitutes the <c5> instead. The fact that you can sometimes display it is because

what is the function naming convention?
...ackages" states that it depends on the classes and instances. I couldn't find more hints. And there's more: - using underscore characters: check_tzones, Cstack_info, R_system_version (etc) - using interCapping: closeAllConnections, rawToChar, rowSums, toString, tryCatch, writeLines (etc) - using dots and intercapping: as.Date, julian.Date, toString.default (etc) So, an entire zoo of function names. Did I miss a system, or is it arbitrary (within the set of accepted characters) ? What is the best way to name one's own functions? Thanks in advance, Franklin...

I already have a few C subroutines that I access from R but I would like to be able use R's connection related functions - readLines, writeLines, cat, read.table, etc - directly. Does any one have any suggestions on how a I should proceed to create a new connection type? Is it even possible without going down to R's guts?
