[R] Generating 3Dplot in lattice package

Dear R users,

I am trying to generate a 3D plot using the wireframe() function in the lattice package.

The corresponding formula in Excel looks as follows and is applied to the wireframe() function:


I tried to "translate" this formula in R and the code looks as follows


In this case I get only one value which is NAN but I should get a time series with 13000 values. Hence, I deleted the min() function and tried the wireframe() function:


However, it doesn't work as the formula for the inflator is incorrect. It produces NANs although it shouldn't do that and actually doesn't do that in Excel. Furthermore, the results are totally different to those calculated by Excel.

Can anyone help me with the formula and translate it correctly in terms of R? How do I get the time series? How do I get the values I get in Excel?

I have attached the data as csv file to this email.

Thank you very much for your help.
