Hi there,
I would like to remove all messages when I load library (I fact I am
using "require" and "install.packages"). I tried many options and look
at the documentation for the 2 functions.
For example I am using the following piece of code: init.R
print("step 1")
# Install library if not installed
if (!require("plyr",quietly=TRUE,warn.conflicts=FALSE))
suppressMessages(install.packages("plyr",quietly=TRUE))
if (!require("dplyr",quietly=TRUE))
suppressMessages(install.packages("dplyr",quietly=TRUE))
if (!require("stringr",quietly=TRUE))
suppressMessages(install.packages("stringr",quietly=TRUE))
if (!require("readr",quietly=TRUE))
suppressMessages(install.packages("readr",quietly=TRUE))
if (!require("tidyr",quietly=TRUE))
suppressMessages(install.packages("tidyr",quietly=TRUE))
if (!require("XML",quietly=TRUE))
suppressMessages(install.packages("XML",quietly=TRUE))
if (!require("Rcpp",quietly=TRUE))
suppressMessages(install.packages("Rcpp",quietly=TRUE))
if (!require("rbenchmark",quietly=TRUE))
suppressMessages(install.packages("rbenchmark",quietly=TRUE))
if (!require("tiff",quietly=TRUE))
suppressMessages(install.packages("tiff",quietly=TRUE))
if (!require("xlsx",quietly=TRUE))
suppressMessages(install.packages("xlsx",quietly=TRUE))
if (!require("ROracle",quietly=TRUE))
suppressMessages(install.packages("T:/CH/R/ROracle_1.2-2.zip", repos =
NULL, type = "source",quietly=TRUE))
print("step 2")
and I run the code in this way:
> source("./init.R",encoding =
"UTF-8",verbose=FALSE,echo=FALSE,print.eval=FALSE)
and I get the following output that I don't manage to remove:
[1] "step 1"
Attache Paket: ‘dplyr’
Die folgenden Objekte sind maskiert von ‘package:plyr’:
arrange, count, desc, failwith, id, mutate, rename, summarise,
summarize
Die folgenden Objekte sind maskiert von ‘package:stats’:
filter, lag
Die folgenden Objekte sind maskiert von ‘package:base’:
intersect, setdiff, setequal, union
[1] "step 2"
What is the way to get no messages at all when loading library ? ( or
using other R function in general).
I am trying to keep only the important messages and so far I am getting
way too much messages.
Thanks
Cheers
Fabien
