我看了新人发帖指南，想要发一个求助贴，按照指南上写的用reprex()粘贴运行结果，但是使用的时候遇到这样的问题：
ask <- Merge_finalranked[,4:5]
#> Error in eval(expr, envir, enclos): object 'Merge_finalranked' not found
with(ask,plot(x=Mean,y=n.study))
#> Error in with(ask, plot(x = Mean, y = n.study)): object 'ask' not found
dput(ask)
#> Error in dput(ask): object 'ask' not found

从中可以看到，reprex函数没读取到我的environment的数据集，请问怎么才能让它正确读取到？
