...anyone got the last 10% please?
CONTEXT:
Data is received where one of the columns is a datetimestamp. At midnight,

e.g. "01/09/2009". At other times, the value in the column contains both
date and time e.g. "01/09/2009 00:00:01". The goal is to read it into R as
an appropriate data type, where for e...

Error in formatDL(nm, txt, indent = max(nchar(nm, "w")) + 3)
This error can arise when getOption("width") is too small. 80 seems to be the
limit for me with R-3.3.2 on Windows.

Curious treatment of entities in xmlTreeParse
...TreeParse(a, replaceEntities=FALSE, asText=TRUE)
I'm guessing this is what breaks things when I try to do things with tm:
rss2Reader <- readXML(
spec = list(
Author = list("node", "/item/creator"),
Content = list("node", "/item/description"),
DateTimeStamp = list("function",function(x) as.POSIXlt(Sys.time(),
tz = "GMT")),
Heading = list("node", "/item/title"),
ID = list("function", function(x) tempfile()),
Origin = list("node", "/item/link")),
doc = PlainTextDocument())

Error in formatDL(nm, txt, indent = max(nchar(nm, "w")) + 3)
It happens in the fda package because some of the headers are longer
than typical (e.g., "Repository/R-Forge/DateTimeStamp") and formatDL
dies if the indent argument is too large compared to the width argument.
It might be nice to change formatDL so it never gave such an error, but
did something reasonable when the 'indent' argument was too big.

Problem with Snowball & RWeka
Dear Forum,
when I try to use SnowballStemmer() I get the following error message:
"Could not initialize the GenericPropertiesCreator. This exception was
produced: java.lang.NullPointerException"
It seems to have something to do with either Snowball or RWeka, however I
can't figure out, what to do myself. If you could spend 5 minutes of your
valuable time, to help me or give me a
