Hi,
batch is a vector of lines returned by readLines from a
NL-line-terminated file, here is the relevant section:
=========================================================
AA BB CC DD EE FF
GG H
H JJ KK LL MM
=========================================================
as you can see, a line is corrupt; two CRLF's are inserted.
This is okay, I drop the bad lines, at least I hope I do:
conn <- textConnection(batch)
field.counts <- count.fields(conn, sep="\t", comment.char="", quote="")
close(conn)
good <- field.counts == 8 # this should drop all bad lines
if (!all(good))
batch <- batch[good]
conn <- textConnection(batch)
ret <- read.table(conn, sep="\t", comment.char="", quote="")
close(conn)
I get this error in read.table():
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, :
line 7151 did not have 8 elements
how come?!
also, is there some error recovery?
e.g., the code above is a part of a function - is there a way to recover
batch (without re-running the whole thing)?
Thanks!
