error in LD proxies

[Xuemin-Wang]

Hi gwasvcf developer(s) and users,

I tried to get proxies for variants but encountered an error below. This is similar to a previous issue (#13), which hasn't been responded. So I opened this one here.

bmi_proxy <- query_gwas(bmi, rsid=bmi_snps$snp, proxies = "only", bfile = ldfile, tag_r2=0.6)

Taking input= as a system command ('gunzip -c C:\Users\xueminW\AppData\Local\Temp\RtmpwvwlJ4\file2d1c5b7c431a.targets.ld.gz') and a variable has been used in the expression passed to input=. Please use fread(cmd=...). There is a security concern if you are creating an app, and the app could have a malicious user, and the app is not running in a secure environment; e.g. the app is running as root. Please read item 5 in the NEWS file for v1.11.6 for more information and for the option to suppress this message.
'gunzip' is not recognized as an internal or external command,

Error:

Backtrace:

1. gwasvcf::query_gwas(...)
2. dplyr <fn>(<rln_____>)

Was this because the query makes changes to the environment and I don't have admin rights?

Many thanks,
