summary of a list
Hello,
I'm using the following for loop to find regression curves using a list of functions (formList), a list of starting
values (startList), uppervalues (upperList) and lower values (lowerList).
A sample of the list of function I use in the loop is the following:
FormList <- list(PTG.P ~ fz1(Portata, a, b), PTG.P ~ fz2(Portata, a, b), PTG.P ~ fz3(Portata,a, b, d, e),
PTG.P ~ fz4(Portata, a, b), PTG.P ~ fz5(Portata, a, b, d), PO4.P ~ fz1(Portata, a, b),
PO4.P ~ fz2(Portata, a, b), ......

non linear regression with nls
Hello,
I'm a beginner with R and it's the first time I'm using the R-help list... I hope I'm in the right place, if not:

"river.name" "Portata" "PTG.P" "PO4.P" "NT.N" "NH4.N" "NO3.N" "BOD5" "SiO2"
