Dear all,
I want to import just part of an excel data file into R.
I would like to have the data imported without
rownames or colume names.
I used read.delim("clipboard", header=F). Somehow even though
I added the argument "header=F", I still have the row names V1,
V2, ...,
Does anyone know how to fix this?
Thanks very much in advance.
You could use readLines() or you could use scan().
Perhaps:
input <- scan(file="clipboard", what="numeric")
If you know the number of columns, say 10, it could be:
inpmat <- matrix( scan(file="clipboard", what="numeric"), ncol=10)
Or perhaps:
inpmat <- matrix( scan(file="clipboard", what=double() , ncol=10)
Using the first version actually gives you character values, since
"numeric" is of of type character. Different convention than most
other reading functions.
