GLS with nlme
Hello All,
This is my third time attempting to post this message. I don't see it
in the archive, so I'm guessing it is not getting through. If I am
wrong, my apologies.
I am trying to do a GLS regression, (X'V^-1X)^-1X'V^-1y, using the gls()
function from the nlme package. I have the covariance matrix V. I have
been searching for a way to specify the correlation structure

qr() and Gram-Schmidt
Hi,
Why the qr() produces a negative Q compared with Gram-Schmidt? (note
example below, except Q[2,3])

compare the output with qr.Q()
a <- c(1,0,1)
b <- c(1,0,0)
c <- c(2,1,0)
x <- matrix(c(a,b,c),3,3)

file.c: File digits/ett does not exist in any format
I'm using Swedish on version 1.4.13. The full part of the
log is:
[Oct 13 12:51:16] WARNING[7810] file.c: File digits/ett does not exist in any format
[Oct 13 12:51:16] WARNING[7810] file.c: Unable to open digits/ett (format 0x8 (alaw)): No such file or directory
The word 'ett' means 'one'. We have two words for one: 'en' and 'ett'.
Any idea how to fix/solve

Question about "evalq"
The help page of eval says: The 'evalq' form is equivalent to
'eval(quote(expr), ...)'. But the following is not equivalent. Can
anyone give me some explaination? Thanks very much.
> f1 <- function(x,digits=5) lapply(x, f2)
> f2 <- function(x) eval(quote(print(x+1,digits=digits)),list(x=x),parent.frame(2))
> f1(list(x1=1))
