Datasets from loaded packages

[Felipe Carrillo]

Hi:
I read about Deducer when it first came out but I just now gave it a
try. I have to say that it is
a great way for newbies to plot their data without having to type or
know anything about R. I do have
a couple of questions though;
1 - Is there a way to see the code generated when a user clicks on the
any of the menus?
2- Rcmdr has a dropdown combo box where the user can select datasets
from loaded packages to practice; does Deducer have that option? If
not, could that be included?
I am just now started my first session of Deducer and at first glance
it looks awesome but I didn't see the options mentioned above. Thanks
Ian for the great work.

The code is sent to the console when you hit 'Run', so you can see it
there. In the plot builder there is a menu item 'view call' that
displays the generated code.

There currently is not, but it is very easy to implement. Here is the code:

.makePackageDataDialog <- function(){
dat <- data()$results
RFunction <- J("org.rosuda.deducer.widgets.param.RFunction")
RFunctionDialog <- J("org.rosuda.deducer.widgets.param.RFunctionDialog")
ParamCharacter <- J("org.rosuda.deducer.widgets.param.ParamCharacter")

rf <- new(RFunction,"data")
rf$setTitle("Load Data From Package")

p <- new(ParamCharacter,"data")
p$setTitle("Data set")
p$setOptions(dat[,3])
p$setLabels(dat[,4])
p$setViewType(p$VIEW_COMBO)
rf$add(p)

rfd <- new(RFunctionDialog, rf)
rfd$setSize(250L,125L)
rfd$setLocationRelativeTo(.jnull())
rfd
}

jgr.insertMenuItem("File","Load Package Data Set",
".makePackageDataDialog()$run()",3)

I will include this dialog in the next version of the DeducerExtras package.

Thanks Ian:
Is the new menu created under Data in the JGR console or
should pop up as a new combobox. The reason I am asking is
because I ran the function and can't see it anywhere.

The code I sent creates a menu item in the file menu.

Thanks, just found it.

[Felipe Carrillo]

It works really well, however is there a way to modify the function
to display only the datasets for the loaded packages? The combobox
displays datasets that is hard to tell which package it belongs to.

[Ian Fellows]

It should only show data from loaded packages. type data() into the
console to see where the datasets come from.
