Hi, there So werid that I've got warning messges during installation of xcms (╥╯^╰╥) Does anyone know how to solve it? Many thanks!!!

my codes were shown below: (Exactly the same with official introduction)

'''if (!require("BiocManager", quietly = TRUE))
   install.packages("BiocManager")

BiocManager::install("xcms")'''

And here is the output:

> if (!require("BiocManager", quietly = TRUE))

Details were showed in this sreenshot:

You didn't get an error. You got a warning. Did you read what it said? It seems pretty self-explanatory, and also gives you other things you can read for further information.

In addition, you can just copy and paste the output and then highlight and click the button that says 'CODE' to make it more legible.
