如何燮preSS输出

问题描述：

我想燮preSS输出R中，当我从命令提示符下运行我的ř脚本。

I would like to suppress output in R when I run my R script from the command prompt.

我试过很多选项，包括 - 从和 - 香草。这些选项减轻输出的文字量。

I tried numerous options including --slave and --vanilla. Those options lessens the amount of text outputted.

我也尝试管道输出到 NUL 但这并没有帮助。

I also tried to pipe the output to NUL but that didn't help.

答

看看帮助（汇）来做到这一点。在Unix上我会做

Look at help(sink) to do that. On Unix I'd do

sink("/dev/null")    # now suppresses
....                 # do stuff
sink()               # to undo prior suppression, back to normal now

和Windows当量（带尖的最帽子约翰内斯）是

and the Windows equivalent (with a tip-of-the-hat to Johannes) is

sink("NUL")
....
sink()
