about sink and scan
...get current size of file. but how can I check
which is new output or old one within the same line ,then scan the latest.
example:
sink('test.txt')
cat("r sink")
scan('text.txt',what='character',blank.lines.skip=FALSE,sep='\\n',skip=0,quiet=TRUE)
cat("htuierghtue")
scan#this time I just want to scan the "htuierghtue"
sink()
