Hi everybody,
Hope your are not all on holyday because I've got a problem that is going to
drive me crazy...
I would like to remove some rows from a dataframe. The rows correspond to
some
specific indexes which I can get by looking at the name in the first column
of my dataset. But I manage to
Have you noticed any problems with big dates (=1/1/2040) in R?
Here is the bit of code that I'm having trouble with:

Dear all,
I'm importing some data (with read.table, file .txt) but I have some

Dear Thomas,
I wonder if you have any NAs in xy$x or xy$y.
The Dataframe looks like the following:

Why should it take months to get these installed ?
Both R and emacs are simple and free to install. If high speed internet access is a
problem, you can always download these from some Internet Café or a friend, burn it
into CD and install onto the machines.

I'm trying to use the regexpr function to locate the decimal in a character

Hi Folks,
With a bit of experimentation I have determined (I think)
that on my R implementation the largest positive integer
that is exactly represented is (2^53 - 1), based on
(((2^53)-1)+1) - ((2^53)-1)
[1] 1
((2^53)+1) - (2^53)
