r - 关于屏蔽函数的静音消息

Question

我试图消除解释某些功能被其他包屏蔽的消息。我尝试了不同的组合，但没有一个能满足我的需求。

我拥有的块是:

<<loadpkgs, echo=FALSE, warning=FALSE, message=FALSE>>=
suppressPackageStartupMessages(library(doMC))
suppressPackageStartupMessages(library(aroma.affymetrix))
suppressPackageStartupMessages(library(crlmm))
suppressPackageStartupMessages(library(snpStats))
suppressPackageStartupMessages(library(pd.genomewidesnp.6))
suppressPackageStartupMessages(library(GenomicRanges))
suppressPackageStartupMessages(library(ggbio))
@ 

但是输出(我希望没有)是(在生成的 PDF 上):

## Loading required package:  foreach
## foreach:  simple, scalable parallel programming from Revolution Analytics
## Use Revolution R for scalability, fault tolerance and more.
## http://www.revolutionanalytics.com
## Loading required package:  iterators
## Loading required package:  parallel
## Loading required package:  R.utils
## Loading required package:  R.oo

##
## Attaching package:  ’R.oo’
##
## The following objects are masked from ’package:methods’:

##    getClasses, getMethods

关于如何解决这个问题的任何想法？

Answer 1

设置参数 warn.conflicts=FALSE在 library()如

library(dplyr, warn.conflicts=FALSE)

应该做的伎俩。当可能有数百个或更多内核加载库时，这对于并行计算特别有用。
