can't get names from vector in nlm calls
I've been trying to figure out how to get the names of the parameter vector
variables when inside the function that nlm calls to return the objective
function value:
knls <- function( theta, eqns, data, fitmethod="OLS", instr=NULL, S=NULL )
{
## print( names( theta ) ) # returns NULL
## get the values of the parameters
for( i in 1:length( theta ) )
{
val <- theta[i]
storage.mode( val ) <- "double"
assign( names( theta )...

getting names of p vector in nlm function...
