Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipes/r-visualizer) and found it was in an excellent condition.

@conda-forge/help-r please can you help me with the win_64 win build error?

The reported errors are:

• Encountered problems while solving:
• • package r-transformer-2.1.0-r36ha770c72_0 requires r-base >=3.6,<3.7.0a0, but none of the providers can be installed
• • nothing provides m2w64-openblas needed by r-base-3.5.1-h0c8e037_1006

I don't understand why r-base-3.5.1 it's been used here.

Dear @dbast and @conda-forge/help-r

Now the win64 build reports different dependency conflict:

The reported errors are:

• Encountered problems while solving:
• • package r-sm-2.2_5.4-r3.4.1_0 requires r-base 3.4.1*, but none of the providers can be installed
• • nothing provides m2w64-openblas needed by r-base-3.5.1-h0c8e037_1006

The linux_64 build test is working, can we merge?
