I am trying to create a interface where the user can key in a number for the script to run. However, I am unable to retrieve the value keyed into gedit. Can anyone help me? Here's what I have done:

require(gWidgets2RGtk2) #Load package
w=gbasicdialog("key number")

推荐答案

我在这里所做的与jverzani建议的相同

What I have done here is the same as suggested by jverzani

require(gWidgets2RGtk2) #Load package
 w = gbasicdialog("key number")
 a <- gedit("1",cont=w)
 addHandlerKeystroke(a, handler=function(h,..) { 

    number <- svalue(a)
    print(number)
 })
 visible(w)=TRUE
