我拼凑了一个 Emacs 函数以便发送
tOne <- proc.time()[3]
在我的“send-to-R”键之前,然后是
tTwo <- proc.time()[3]
之后,然后打印差异。印刷变得相当混乱。
R中是否有更好的方法来自动计时发送到R的所有内容?(例如在 F# 中#time "on")
编辑:目前,它发送一些额外的换行符,因为劣质缓冲区需要发送字符串:
> > a<-ocorrelate.parallel(replicate(2, rnorm(100000)), 0.5)
> 
+  user  0.072 sys  0.020 elapsed 14.925 
> > a<-ocorrelate.parallel(replicate(2, rnorm(100000)), 0.5)
> 
+  user  0.088 sys  0.032 elapsed 16.868 
> > 
功能:

  (process-send-string "R" "ttwo <- proc.time()[1:3]; cat(paste(c(\"\", 
        format(ttwo-tone)), c(\"user\", \"sys\", \"elapsed\", \"\n\")));")
