Hi everyone,

Following this post:
http://r.789695.n4.nabble.com/currency-conversion-function-tt906056.html#a906061


I was trying to run the code:

foo <- function(from, to, date){
      url <- "
http://www.oanda.com/convert/classic?script=..%2Fconvert%2Fclassic&language=en&value=1
"
      params <-
sprintf("%s&date=%s&exch=%s&exch2=&margin_fixed=0&expr=%s&expr2=&SUBMIT=Convert+Now&lang=en&date_fmt=us",
url, format(as.Date(date), "%m/%d/%y"), from, to)
        Lines <- readLines(params)
        value <- gsub(".*([0-9]\\.+[0-9]+).*", "\\1", grep("nl", grep(from,
grep(to, Lines, value = TRUE), value = TRUE), value = TRUE))
        as.numeric(value)
}

foo('BRL', 'USD', '2010-10-14')

But it gives me the following:

numeric(0)
Warning message:
In readLines(params) :
  incomplete final line found on '
http://www.oanda.com/convert/classic?script=..%2Fconvert%2Fclassic&language=en&value=1&date=10/14/10&exch=BRL&exch2=&margin_fixed=0&expr=USD&expr2=&SUBMIT=Convert+Now&lang=en&date_fmt=us
'


Does anyone what the problem is about?

If I type simply:

> getFX("EUR/USD",from="2011-01-01")

Then I get similar error:

[1] "EURUSD"
Warning message:
In readLines(tmp) :
  incomplete final line found on
'xxx\AppData\Local\Temp\RtmpI1HUzb\file27f7532'

(I've hide the path)

Thanks
