Robert,
How can I define parameters in the functions within overlay() ?
For example:
> fun3 = function(x,y)
{a=-1.1867422
s=1.0287373
return((y-(a+s*x))/sqrt(s^2+1))}
> NmaxDev =
> overlay(bN1999max,bN2009max,fun=fun2,filename="NmaxDev",overwrite=TRUE,format="EHdr",datatype='FLT4S',
> NAflag=0)
want it to be something like:
> fun3 = function(x,y,a,b)
{return((y-(a+s*x))/sqrt(s^2+1))}
> NmaxDev =
> overlay(bN1999max,bN2009max,fun=fun2(a=-1.1867422,s=1.0287373),filename="NmaxDev",overwrite=TRUE,format="EHdr",datatype='FLT4S',
> NAflag=0)
Is it possible or should I redefine the function every time?
