Re: [R] file reading /problems with encoding

Quoting Uwe Ligges : R is not able to re-encode the file to the native encoding. But if you keep it in UTF-8, what is the problem to grep for the specific characters (as grep and friends support the argument useBytes these days)? The Problem with UTF-8 is that I'm not able to cat a valid xml-

Re: [R] file reading /problems with encoding

Hello Uwe, Quoting Uwe Ligges : You can arrange the former without a loop by xml <- paste(t, collapse="") Thank you, another trick to improve my R-skills :) For the other problem you are reporting: Can you make (the relevbant part of) your file available (say on some web site) so that we can

[R] file reading /problems with encoding

Hello, I'm a little frightened because of a problem that occured lately as I tried to read in a xml-file (for replacing some variables in the string with values from a data frame). The almost biggest problem is the encoding of the xml-file. Since it is generated by Word 2007 its encoding

[R] Convert data frame to XML-Tree

Hello, I'd like to convert R data frames into xml-trees. I wrote (and copied) this little program to do this: convertToXML <- function(df,name) { xml <- xmlTree("Test") xml$addNode(name, close=FALSE) for (i in 1:nrow(df)) { xml$addNode("value", close=FALSE) for (j in names(df)) {
