Hello,
here are the results from using dput() on the objects in question.
>dput(blaah)
structure(list("Insert single selection box title here", "Insert slider bar
title here",
"SingleSelect", "Slider", 1, 50, list("Option a", "Option b",
"Option c"), list(0, 100)), .Dim = c(2L, 4L), .Dimnames = list(
c("exampleSingleSelect", "exampleSlider"), NULL))
>dput(parameterList[aCounter, 3])
list(structure(list("Insert single selection box title here",
"Insert slider bar title here", "SingleSelect", "Slider",
1, 0, list("Option a", "Option b", "Option c"), list(0, 100)), .Dim =
c(2L,
4L), .Dimnames = list(c("exampleSingleSelect", "exampleSlider"
), NULL)))
The matrix parameterList was constructed as followed:
<R script>
exampleSlider = list("Insert slider bar title here", "Slider", 0,
list(0,100))
exampleSingleSelect = list("Insert single selection box title here",
"SingleSelect", 1,
list("Option a", "Option b", "Option c"))
parameterList = rbind(list("more advanced options", "Button",
rbind(exampleSingleSelect,exampleSlider ), " ")
...
aParameterValue <- as.matrix(parameterList[[aCounter,3]])
...
blaah <<- aParameterValue
...
parameterList[aCounter, 3] <<- blaah
</R script>
As a side note: The ... represents various other lines. The
construction parameterList <<- blaah <<- aParameterValue is an ad-hoc
solution to using global and local variables that I will try to smooth over
once it works as it is now. To be more specific, the value aParameterValue
is a local variable that is created in a subfunction which is called upon
once for each row in parameterList, each time the user presses a button in
the created tcltk window.
The blaah variable is a global variable that solves the problem of tlctk
buttons not being able to receive the returned values from the function it
calls and parameterList somehow not being able to be updated correctly
within this function.
I hope anyone can make sense of this story :S
