hi ,I am writing a soft package based on R.
But when I try to read a configure file showed as below.
How can I read the parameter in this text file.
How can I read the parameter into each variable in this file ?
configinfo<-scan(file(configfile),ok=TRUE,n=-1)
scan seems need every line have same column ?
configinfo <- readLines(configfile,ok=TRUE,n=-1)
methodnum <- unlist(strsplit(configinfo[2],":"))[2]
methodname <- unlist(strsplit(configinfo[3],":"))
time <- strtrim((unlist(strsplit(configinfo[4],":"))[2]),3)
and
time is a string "3 "
and
strtoi(time) failed and is "[1] NA"
when
time <- strtoi(strtrim((unlist(strsplit(configinfo[4],":"))[2]),1))
time is a integer "6"
actually this parameter could be a 1 to 4 digital number from 1 to 9999
How could I can read this kind of variables into my config R file?
thank you
