You can use the `gWidgets` package to do this kind of thing easily enough:

require(gWidgets)
my_vec <- character(0)
items <- state.name ## some  values

handler <- function(h,...) my_vec <<- svalue(h$obj)

w <- gwindow()
g <- ggroup(cont=w, horizontal=FALSE)
## one way to select one or more from many
gcheckboxgroup(items, cont=g, use.table=TRUE, handler=handler)
