Subject: [R] Pulling strings from a Flat file
Hi,
I have a flat file that contains a bunch of strings that look like this. The
file was originally in Unix and brought over into Windows:
E123456E234567E345678E456789E567891E678910E. . . .
Basically the string starts with E and is followed with 6 numbers. One
string=E123456, length=7 characters. This file contains 10,000's of these
strings. I want to separate them into one vector the length of the number of
strings in the flat file, where each string is it's on unique value.
cc<-c(7,7,7,7,7,7,7)
> aa<- file("Master","r", raw=TRUE)
> readChar(aa, cc, useBytes = FALSE)
[1] "E123456" "\nE23456" "7\nE3456" "78\nE456" "789\nE56" "7891\nE6" "78910\nE"
> close(aa)
> unlink("Master")
The biggest issue is I am getting \n added into the string, which I am not sure
where it is coming from, and splices the strings. Any suggestions on getting
rid of the /n and create an infinite sequence of 7's for the string length for
the cc vector? Is there a better way to do this?
