Sample

https://conda.io/docs/user-guide/configuration/sample-condarc.html

# channel locations. These override conda defaults, i.e., conda will
# search *only* the channels listed here, in the order given.
# Use "defaults" to automatically include all default channels.
# Non-url channels will be interpreted as Anaconda.org usernames
# (this can be changed by modifying the channel_alias key; see below).
# The default is just 'defaults'.
channels:
  - r
  - defaults

# Show channel URLs when displaying what is going to be downloaded
# and in 'conda list'. The default is False.
show_channel_urls: True

# For more information about this file see:
# https://conda.io/docs/user-guide/configuration/use-condarc.html

• It adds the r Anaconda.org channel and enables the show_channel_urls option.
