Hi everybody,

any idea why showMethods fails with the following error when printTo is set to false, i.e. to return the output as a character vector. It works fine if printTo is left default as seen below. The behaviour is consistent for any method I tried. stdin() generally works fine on this system, at least when checked with: x = readLines().

Thanks,
Oleg

> x = showMethods("plot", printTo=FALSE)
Error in cat(file = printTo, sep = "", ...) :   cannot switch output to stdin

Enter a frame number, or 0 to exit

  1. showMethods("plot", printTo = FALSE)
  2. .showMethodsTable(fdef, includeDefs, inherited, classes = classes, showEmpt
  3. doFun(f, p)
  4. cf("Function: ", func, " (package ", pkg, ")\n")
  5. cat(file = printTo, sep = "", ...)

Selection: 0
> x = showMethods("plot")

Function: plot (package graphics)

x="ANY", y="ANY"
x="SimResults", y="SimResults"
x="SimResults", y="missing"
x="TimeDateBase", y="character"
x="TimeDateBase", y="data.frameOrMatrix"
x="TimeDateBase", y="missing"
x="TimeSeries", y="missing"
