[ncl-talk] Error in NCL sample script: Undefined identifier (regline_stats)

[Rick Brownrigg]

Hi,

Yes, Barry is correct, the docs on this function do explicitly state the
function was introduced in v6.2.0:

http://ncl.ucar.edu/Document/Functions/Contributed/regline_stats.shtml

The current version of NCL is v6.4.0   BTW: as of somewhere in the version
chain (6.3.0 perhaps?), its no longer necessary to explicitly load the core
libraries -- they are loaded automatically.

Rick
