[gradsusr] how to create taylor diagram by Grads

[NEHA SHARMA]

Dear Thanh, NT
It is difficult to create at taylor diagram in grads,However it is much
easier to implement using R package available from
http://cran.r-project.org/bin/windows/base/

After downloading the above package, you need a plotrix package available
here:
http://cran.r-project.org/web/packages/plotrix/index.html

The refernce manual of plotrix package is available on the same page.

First you need to install plotrix package and then load it.
Then use the following example:
obs<-c(1,2,3,3,4,5,6)
model<-c(2,3,8,9,7,6,5)
taylor.diagram(obs,model,pos.cor=FALSE)

To add the second data series,after the above three lines use the below
line:
model2<-c(1,2,3,4,6,7,5)
taylor.diagram(obs,model,pos.cor=FALSE,add=TRUE)

The final result will display three points respective to your three columns.

Hope this helps.

Thanks & Regards,
