[R] textConnection

[Gabor Grothendieck]

1. closeAllConnections() will close all open connections so

con <- textConnection(Line)
closeAllConnection()
# now there are no open connections left

2. close() will close an individual connection:

con <- textConnection(Line)
scan(con, what = "")
close(con)

3. strsplit will split your line without using connections

 strsplit(gsub(" +", " ", Line), " ")

3a. This is the shorter for the case that there is exactly one space
between words:

 strsplit(Line, " ")
