hi, i've moved rkwarddev and XiMpLe into a new folder at root level, "packages", as you suggested (svn move threw me an error, i had to re-add the files, hope nothing got lost there).
also, rkwarddev gained some quite experimental stuff to generate JavaScript
code with R. as said before i mostly wanted to be able to use the XML objects
and have them replaced with their ID in the code, which is basically working
now with a function i called id():
# first create an example checkbox XML node
cbox1 <- rk.XML.cbox(label="foo", value="foo1", id.name="CheckboxFoo.ID")
# some useless demonstration of id()
id("cbox1 has the ID ", cbox1, "!")
# returns: "cbox1 has the ID CheckboxFoo.ID!"
cat(id("cbox1 has the ID ", cbox1, "!", quote=TRUE, collapse=" + "))
# returns: "cbox1 has the ID " + CheckboxFoo.ID + "!"
so this can be used to paste() together anything manually. but i also
implemented two very common cases for convenience:
echo("bla <- \"", cbox1, "\"")
# with cat() generates:
# echo("bla <- \"" + CheckboxFoo.ID + "\"");
# so echo() creates a JS clone of itself...
ite(id(cbox1), echo("bar <- \"", cbox1, "\""), echo("bar <- NULL"))
# ite is just short for if/then/else, so this produces:
# if(CheckboxFoo.ID) {
# echo("bar <- \"" + CheckboxFoo.ID + "\"");
# } else {
# echo("bar <- NULL");
# }
viele grüße :: m.eik
