How to avoid to print the vcfR header? It gives me some trouble for further analysis to the log files. Thanks

Hi @Shicheng-Guo , I'm afraid I do not understand your question. Your post reports the results of the show() method. This means that you had to have requested this information. Can you create a minimal reproducible example to illustrate the behavior you'd like to change? I have some suggestions here.

@knausb This is not output of show() method, but of .onAttach function/hook: https://github.com/knausb/vcfR/blob/master/R/zzz.R

@Shicheng-Guo its annoying, isn't it? The only way to do this is with suppressStartupMessages(library("vcfR")).

Since some people just put message() instead of packageStartupMessage() in their .onAttach code, sometimes you need to do suppressMessages(library(pkg)).

Define it as silent function, like Dirk did, and use it for these annoying pkgs:
