#' Instead of writing:
#' rm(list=ls(pattern="^t[.]"))
#' one can write
#' cleanup()
#'
#' You can also expressly specify objects to clean up:
#' cleanup(c("^temp_var$","^x$"))

cleanup<-function(pattern="^t[.]"){
    for(p in pattern){
        objs <- ls(pos = ".GlobalEnv")
        rm(list = objs[grep(p, objs)], pos = ".GlobalEnv")
    }
