What is the variableType question asking for? thanks, Paul

> RTT.widget <- ggenericwidget(wizard_read_data)
Select a GUI toolkit

1: gWidgetsRGtk2
2: gWidgetstcltk

Selection: 1
Loading required package: gWidgetsRGtk2
Need to implement variableType

addComponent(win, btn_calc, 501, 1000, 601, 1, rightType = “REL”)

should be

addComponent(win, btnCalc, 501, 1000, 601, 1, rightType = “REL”)

HTH :)

in the end of the gWidgets code, it should be :
frmResults <- gframe("results", container = win)
lblP <- glabel(labelP, container = frmResults)
txtP <- gedit(container = frmResults)

instead of the current :
frmResults <- gframe("results", container = win)
lblP <- glabel(labelP, container = frm_results)
txtP <- gedit(container = frm_results)

Thanks for your post anyway, never had the courage to find for those GUI tools, you just made me discover 2 of those :)

That’s more about learning R, whereas as lsp is about “I’m sure utils had a function for getting 8 character DOS names, but I can’t remember what it was called.” So you type lsp(utils), and a quick perusal of the results reveals shortPathNames.

The R GUI autocompletion only lists the first 10 or so results, so I find it’s better for completion than discovery (unless you know the first few characters of what you are looking for).

Also, autocompletion varies between development environments. I mostly use eclipse these days, and it doesn’t limit completions to a particular package, even if you explcitily type ::.

Quite useful to discover new functions… It’s called unknownR (http://cran.r-project.org/web/packages/unknownR/index.html) and has been presented at LondonR (http://www.londonr.org/unknownR.pdf).

base:: TAB TAB

or

base::: TAB TAB

to see all including non-exported functions?

Much faster and very easy to remember. In addition: by using :: yiou can sirectkly use that function, and the same applies for ::: if you want to use non-exported functions.

Cheers,

Rainer
