Not so much a mystery. read.table() only looks at the first 5 lines
when
decided how many columns your file has (as described in the Details
section of the help).
The easiest solution is to add a col.names argument to read.table()
with
the correct number of names.
You may want to also include as.is=TRUE if you don't want your data to
be imported as factors. If you expect character but have factor you
may
get unexpected results later.
There is also a fill argument for read.table that may be needed when
the length of colClasses or col.names exceeds the length of some rows.

Hello,
Please have a look at the code below, which I use to read in the
attached
file. As line 18 of the file reads "1065:>sp|Q9V3T9|ADRO_DROME
NADPH:adrenodoxin oxidoreductase, mitochondrial OS=Drosophila
melanogaster
GN=dare PE=2 SV=1", I expect the code below to produce a 3 column
data frame
with most of the last column empty and line 18 to produce a
data.frame row
like so:
V1
1065
V2
sp|Q9V3T9|ADRO_DROME NADPH
V3
adrenodoxin oxidoreductase, mitochondrial OS=Drosophila
melanogaster GN=dare PE=2 SV=1
Why is that not so?
Thanks for any hint.
Sincerely, Joh
read.table(
"/tmp/testfile.txt",
sep=":",
header=FALSE,
quote="",
fill=TRUE
)[19,]
