Error setting TCP_NODELAY

[r2evans]

On startup, I am consistently getting a fail on the first attempt to connect, but it works on the subsequent attempt(s):

library(rredis)
ref <- redisConnect(returnRef=TRUE)
# Error in .openConnection(host = host, port = port, nodelay = nodelay,  : 
#   Error setting TCP_NODELAY
ref <- redisConnect(returnRef=TRUE)

I get the error with or without returnRef, with non-default host/port, and with timeout specified or not. I've started R with --vanilla --no-site-file --no-init-file to ensure I'm not poisoning it somehow.

It does not fail with nodelay=FALSE.

This was fixed in the dev version, not yet on cran. I really need to update
that.

try

devtools::install_github("bwlewis/rredis")

I think that should work. I'll try to get the cran package updated...

I have same problem but interestingly enough it fails only when I run from Rscript but works under Rstudio.
