I have a txt file (attached) that defines equivalents among characters
in latin1 (or iso-8859-1), numeric &#xxx; codes, HTML entities
and latex equivalents. A portion of the file is shown inline below, but
may not be rendered well in this email.
I'd like to read this into R to use as a character translation table,
but am stuck on two things:
- The 5 fields in the file are column-aligned and are separated by 2+
white space characters.
In perl this is trivial to read and parse via something like
@entries = split("\n", $charTable);
foreach (@entries) {
($desc, $char, $code, $html, $tex) = split(/\s\s+/);
}
AFAIK, the only function for reading such data is utils::read.fwf, but I
have to specify the field widths.
I don't know of any function that allows even a simple regrex like this
as a sep= argument.
- The TeX field contains many backslashed codes that need to be escaped
in R. Is it necessarty
to manually edit the file to change '\pounds' --> '\\pounds', '\S' -->
'\\S', etc. or is there something
like raw mode input that would do this where necessary?
