Get type of all variables

Question

In R, I\'d like to retrieve a list of global variables at the end of my script and iterate over them. Here is my code

#declare a few sample variables
a<-1         


        

Answer 1

Designed to do essentially the inverse of what you wanted, here's one of my toolkit toys:

 lstype<-function(type='closure'){
inlist<-ls(.GlobalEnv)
if (type=='function') type <-'closure'
typelist<-sapply(sapply(inlist,get),typeof)
return(names(typelist[typelist==type]))
}
