Spatial Statistics using R
I am looking for online courses to learn Spatial Statistics using R.
Statistics.com is offering an online course in December on the same topic
but that schedule doesn't suit mine. Are there any other similar modes for
learning spatial statistics using R??? Can someone please advice???
Thank you.
Ravi
