Hi David,
Thank you for your response. But that wasn't what I was looking for.
names=c("Ravi", "Raj","Shubha","Nivriti")
select.list(names) gives a pop up with the 4 names. I just wanted in
the pop up a heading (say BOYS) followed by two names and another
heading (say GIRLS) and the remaining two names.
Is there a way I can include headings in the select.list()
Sorry. that function was not in my experience. You could include the
headings in the list perhaps with some message saying that the
headings are not a legitimate choice. I looked at the code for
select.list and doubt that you can enforce the advice with anything in
the select.list parameters. The vector gets handed off pretty quickly
to .Internal functions You would need to handle undesired user
behavior programatically:
names=c("Boys~(Do not choose)", "Ravi", "Raj","Girls~(Do not choose)",
"Shubha","Nivriti")
select.list(names)
If you wanted more control ove rthe behavior I think you would need to
work with : tk_select.list {tcltk}

Hi R,
I am using select.list
names=c("Ravi", "Raj","Shubha","Nivriti")
select.list(names) provides a drop down to choose one of the 4
names.
However I would like to know if it is possible to create a
classification something like this
select.list(names) should give
See if these beginnings get you any further:
ifelse( names %in% c("Ravi", "Raj") ,"Boys", "Girls")
[1] "Boys" "Boys" "Girls" "Girls"
names[names %in% c("Ravi", "Raj")]
[1] "Ravi" "Raj"
names[!(names %in% c("Ravi", "Raj"))]
[1] "Shubha" "Nivriti"
In any case you will need to provided a master list of either (or
both) boy names and girl names.
Boys
Ravi
Raj
Girls
Shubha
Nivriti
I should be able to choose only one of the names.
I'm afraid that did not make much sense to me.
