Hi there everybody, I would like to be able to modify a string like 'Param_i = Val_i-1' in 'Param_i = Val_i-2' in a text file Indeed I have two arrays : -One for the name of my parameters -One for the new values for each parameter
I would like to write a loop like this one : ... SCAN <- scan("File.txt",sep="\n", what="raw",blank.lines.skip=F) For (i in 1:Nb_param) { sub('Param[i] = Value_i-1','Param[i] = Value_i-2', SCAN) } ... I Know how to modify a string with sub when it is a fixed string : sub("(K =)([0-9]*)",paste("\\1", Value[i,2]),SCAN) But i would like to know if it is possible to use the function paste or something else in the first argument of the function sub. For example, the correct syntax of : ' sub("(Param[i])([0-9]*)",paste("\\1", Value[i,2]),SCAN) ' If I'm not clear enough please let me know.. Thank you for your help.
