List of exposures | TwoSampleMR installation

[shanta...@gmail.com]

Hi,

I have been trying to install TwoSampleMR on my machine - mac OS but i'm not able to install it. I'm getting the following error:

Error: package or namespace load failed for ‘TwoSampleMR’ in namespaceExport(ns, exports):

 undefined exports: check_bcftools, is_forward_strand, make_vcf, vcf_header, write_vcf

Error: loading failed

Execution halted

ERROR: loading failed

* removing ‘/Library/Frameworks/R.framework/Versions/3.6/Resources/library/TwoSampleMR’

Error: Failed to install 'TwoSampleMR' from GitHub:

  (converted from warning) installation of package ‘/var/folders/x4/kbrtf_9936n0x6z22545rscw0000gn/T//RtmpyFfjYt/file9d633f420fa/TwoSampleMR_0.4.23.tar.gz’ had non-zero exit status

Also, it would be great if you can guide/ provide me on how to retrieve the exposure list from the MR-GWAS catalog. 

Thank you.

Best,
