Hello, What you want is a list of lists. Try something like
Parameters <- list(PC_h_m = list(descript = "Point de convergence hauteur en metre", value = 5), PC_Q_m3 = list(descript = "Point de convergence debit en m3/s", value = 805.00)) Hope this helps, Rui Barradas Citando MAURICE Jean - externe <jean-externe.maur...@edf.fr>: > HI, > I am new to R and English is not my natural language. > > I am working on an old R application where there is a matrix > containing parameters. Something like : > parametres=matrix(NA,15,3) > parametres[1,1]<- "Point de convergence hauteur en metre" > parametres[1,2]<- 5.00 > parametres[1,3]<- "PC_h_m" > parametres[2,1]<- "Point de convergence debit en m3/s" > parametres[2,2]<- 805.00 > parametres[2,3]<- "PC_Q_m3" > and so on. >> From 15 parameters, we shall reach 40. > > I'd like to be able to use something like > Parameters$PC_h_m$descript to have "Point de convergence hauteur en metre" > Parameters$PC_h_m$value to have 5 > Parameters$ PC_Q_m3$descript to have "Point de convergence debit en m3/s" > Parameters$ PC_Q_m3$value to have 805.00 > > It's a lot more 'readable' by humans ...
