[R] Annoying startup error message

[Lars Bishop]

I understand the solution would be to unset my "SPARK_HOME" environment
variable. I can do this with Sys.unsetenv() but it does not unset
permanently (only in the session). How can I unset permanently?

Sys.getenv("SPARK_HOME")
[1] "/Users/lars/Downloads/spark-1.6.0-bin-hadoop2.6/bin/spark"

Sys.unsetenv("SPARK_HOME")
Sys.getenv("SPARK_HOME")
[1] ""


Thanks again for you help!
Lars.
