Error with tabix.iobio.io

[swvanderlaan]

Hi,

I am getting this error...

Could not resolve host: tabix.iobio.io

... when running this code:

d <- get_proxies(chrom = "12", pos = 583090, window_size = 1e5, pop = "AFR")

How can I fix this?

Best,

Sander

library(jsonlite)
library(xml2)
 
server <- "http://grch37.rest.ensembl.org"
ext <- "/ld/human/rs42/1000GENOMES:phase_3:EUR"

r <- GET(paste(server, ext, sep = ""), content_type("application/json"))
stop_for_status(r)
     
# use this if you get a simple nested list back, otherwise inspect its structure
# head(data.frame(t(sapply(content(r),c))))
head(fromJSON(toJSON(content(r))))
