I'm trying to read in a tab separated table with read.delim().
I don't particularly care what the row names are.
My data file looks like this:
start stop Symbol Insert sequence Clone End Pair FISH
203048 67173930 ABC8-43024000D23 TI:993812543
TI:993834585
255176 87869359 ABC8-43034700N15 TI:995224581
TI:995237913
1022033 1060472 ABC27-1253C21 TI:2094436044 TI:2094696079
1022033 1061172 ABC23-1388A1 TI:2120730727 TI:2121592459
I have to do something with row.names because my first column has
duplicate entries. So I read in the file like this:
> BACS<-read.delim("testdata.txt", row.names=NULL, fill=TRUE)
> head(BACS)
row.names start stop Symbol Insert.sequence Clone.End.Pair
1 203048 67173930 ABC8-43024000D23 NA TI:993812543 TI:993834585
2 255176 87869359 ABC8-43034700N15 NA TI:995224581 TI:995237913
3 1022033 1060472 ABC27-1253C21 NA TI:2094436044 TI:2094696079
4 1022033 1061172 ABC23-1388A1 NA TI:2120730727 TI:2121592459
FISH
1 NA
2 NA
3 NA
4 NA
Why is there a column named "row.names"? I've tried a few different
ways of invoking this, but I always get the first column named row.names,
and the rest of the columns shifted by one.
Obviously I could fix this by using row.names<-, but I'd like to understand
why this happens. Any insight?
