Perform clumping on the chosen variants using through API
ld_clump_api( dat, clump_kb = 10000, clump_r2 = 0.1, clump_p, pop = "EUR", access_token = check_access_token() )
Dataframe. Must have a variant name column ("variant") and pval column called "pval". If id is present then clumping will be done per unique id.
Clumping kb window. Default is very strict, 10000
Clumping r2 threshold. Default is very strict, 0.001
Clumping sig level for index variants. Default = 1 (i.e. no threshold)
Super-population to use as reference panel. Default = "EUR". Options are EUR, SAS, EAS, AFR, AMR
Google OAuth2 access token. Used to authenticate level of access to data#' @return Data frame of only independent variants
