[Rd] PR#6614

[davidhughjones]

I agree with the submitter that this needs some kind of solution.
Although data.frame[,-12] works, how do I drop a named column (the
most common use case)? (I found this bug while searching for an
answer.)

[Rd] read.fwf only reads one "buffersize" of lines when reading multiline records (PR#8951)

Here's a test case:

tf = tempfile()
cat(file=tf, rep("123", 100), sep="\n")
# this gives a data frame with 100 rows
read.fwf(tf, widths=c(1,2), buffersize=10)

# but this only gives 5 rows!
read.fwf(tf, widths=list(c(1,2), 3), buffersize=10)


I think the correct fix is to replace this line in read.fwf

if (length(raw) < thisblock) 

with

if (nread < thisblock) 


This bug is present in earlier versions, at least up to 2.1.0.

Cheers
David
