[R] comma delimiter & comma in tex

[Gabor Grothendieck]

Preprocess the file surrounding the last field with quotes.  The
xx <- line is for purposes of making it self contained here and in
reality would
be replaced with the commented
line above it.  It simply reads the text in.

The yy <- line
then surrounds the fourth field with double quotes assuming
at least a space separates the fields as in your example.

Finally read.table reads it now that the fourth field
has been protected with quotes and closeAllConnections
closes the dangling connections.

# test data
Lines <- "1, A, 24, The Red House
2, A, 25, King's Home, by the Sea
"

# xx <- readLines("myfile.dat")
xx <- readLines(textConnection(Lines))
yy <- gsub('^( *[^ ]+ [^ ]+ [^ ]+ )(.*)', '\\1"\\2"', xx)
read.table(textConnection(yy), sep = ",")
closeAllConnections()
