Newbie query - reading data into R
Prof Brian Ripley <ripley at stats.ox.ac.uk> writes:
Number Napier 324 Auckland 657 Wellington 879 Christchurch 904 works on your example (with tabs in the file). (S-PLUS behaves differently here, and guesses the first column should be the row names without being told).
So does read.table on Unix - I don't remember it doing anything else?
(On R? Your own example shows it does not!)
Whooops. I assumed that the input file had had the "City" header removed when I saw that display. I honestly didn't believe that S-plus could be that silly (it scans the variables, grabs the first nonnumeric one that has no duplicated values and uses it for rownames!):
On Splus 3.4:
read.table("test.dat", header=T)
Number
Napier 324
..
which is not the same as R 0.63.2:
read.table("test.dat", header=T)
City Number 1 Napier 324
..
is it? That was my point: read.table in R and S-PLUS are subtly different.
Agreed. However, even after noticing the difference, I really don't think that that bit of S-plus behaviour is worth cloning. (S-plus, after duplicating the Wellington line:)
read.table('tmp/testdata',header=T)
City Number 1 Napier 324 2 Auckland 657 3 Wellington 879 4 Wellington 879 5 Christchurch 904
