[R] Purpose of readLines(..., encoding=)?

Hi! I'm wondering what's the use of the 'encoding' argument to readLines(x), as opposed to readLines(file(x, encoding=)). The same question applies to read.table()'s 'encoding' vs 'fileEncoding' arguments. AFAIK only the latter is able to re-encode the read text into the internal representation

Re: [R] Purpose of readLines(..., encoding=)?

UTF-8 is treated specially by readLines(), originally to allow for UTF-8 strings on Windows. See the NEWS for 2.12.0. That is not the case for encoding = latin1. If you have a Latin-1 file in a UTF-8 locale, then readLines(x, encoding = latin1) stores the strings in Latin-1 and marks them,

Re: [R] Base within reverses column order

Thanks, Duncan. Using names is certainly the most reliable solution, but requires remembering to modify the surrounding code when enhancing what's within -- a bug risk source when passing on the code. Are you saying that an automatic reversal as follows may break in the future because R-devel may

Thanoon, Firstly, please remember to reply to the R help list as well so that other may benefit from your questions as well. Regarding your second request, I have written the following as a very naive way of inducing correlations. Hopefully this makes it perfectly clear what you change for

Re: [R] Sweave files into LaTex

If you use knitr, you can do, in master.Rnw Rcode, child=Rcode.Rnw= @ This is the equivalent of \input{} (but not \include{}) at the .Rnw level. At any rate, if you have more than just a few code chunks, you should do your work in master.Rnw and produce master.tex from that using either
