[R] how to remove all messages when loading a library ?

ie 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).

in my DF of the strings starting with a sequence of few words. I guess these days it is standard to use DF with millions of entries so I was wondering how people are doing that in the faster way. Thanks Cheers Fabien -- Dr Fabien Tarrade Quantitative Analyst/Developer - Data Scientist Senior
