using eval to handle column names in function calling scatterplot graph function
I am running R version 2.15.1 in Windows XP
I am having problems with a function I'm trying to create to:
1. subset a data.frame based on function arguments (colname & parmname)
2. rename the PARMVALUE column in the data.frame based on function
argument (xvar)
3. generate charts
plotvar <- function(parentdf,colname, parmname,xvar,yvar ){
subdf <- parentdf[substr(colname,1,nchar(parmname)) == parmname,]
names(subdf) <- sub('PARMVALUE'...

Problem with NLSYSTEMFIT()
...I want to solve a nonlinear 3SLS problem with "nlsystemfit()". The
equations
are of the form
y_it = f_i(x,t,theta)
The functions f_i(.) have to be formulated as R-functions. When invoking
"nlsystemfit()" I get the error
Error in deriv.formula(eqns[[i]], names(parmnames)) :
Function 'f1' is not in the derivatives table
Isn't it possible to provide equations in the form
eq1 ~ f1(x,t,theta) etc. to "nlsystemfit()" ?
Kind regards,
Kilian Plank
