Thanks for your help. The goal is to check for every distinct VRPlanID value that we build the tag Group the corresponding MSTP, MSONPC (distinct) if they're not null/empty in the id part of the tag. So, we group after VRPlanID, then get the distinct values from each record from ...
condition = function(cond) { ifelse (cond == 0, value = 1, value = -1) return(value) } 当我试图运行该函数(例如,条件(0))时,我会得到以下错误消息: 如果(cond == 0,value = 1,value = -1)中出现错误:未使用的参数(值= 1,值= -1) 如何解决此错误? 浏览0提问于2019-07-04得票数 ...
