Hi there, I use R and I would like to be able to modify a file .txt "init_file" like this one :
# ---------------------------------------------------------------------------- # # Parameters A # ---------------------------------------------------------------------------- # # Parameter 1 PA1 = 15 # Parameter 2 PA2 = 3 # Parameter 3 PA3 = 2 # ---------------------------------------------------------------------------- # # ---------------------------------------------------------------------------- # # Parameters B # ---------------------------------------------------------------------------- # # Parameter 1 PB1 = 6 ... I have in a first time stocked the values I want to attribute to each parameter and so I would like to create several config files like the first one but with different values for each parameter. I have an array like this one PA1 PA2 PA3 PB1 .... j=1 12 2 1 5 j=2 10 3 2 4 j=3 11 4 3 6 ... To create each file I use : for (j in 1:Nb_config_file) { file.copy("fichier_init",paste("Config_file",j,sep="")) } How can I do to search in each config file j created to modify the values of the parameters according to the j-th row of the array? I thought about looking for the lines "'Parameter' = Value" and modify this line in "'Parameter' = New_value" but I don't find any function to know the location of each string in my config_file... I could also use such a function to modify the format of the date to replace the ":" by something which can be used in a Directory/file name. Thanks you for your time and for your future help =) Cheers Romain ____________________________________________________ Vous aussi bénéficiez d'1 Go de stockage gratuit en ligne avec Voila http://macle.voila.fr ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
