Mixed Models with my dataset.
But...
exemplo - read.table(exemplo.dat,header=T)
mod - amer(pasvig ~ -1 + harvf + tp(dias,by=harvf) + (1 | pac),
data=exemplo)
Erro em if (from == to)
Try this:
as.data.frame(sapply(sapply(DF, as.character, simplify = FALSE), strsplit, ;))

You can try to hunt for it in the findbestsplit Fortran subroutine. It
uses some thing that's equivalent (but easier to compute), not exactly
identical. Breiman uses whatever computational shortcuts he could find
in his code.

hi,
I try to configure my system so when I click on an .R script, the
script is executed in the R GUI.
I tried to open .R files with different .exe files that I found in the
bin-folder of the R folder (R.exe, Rcmd.exe, Rgui.exe ...).
But I always get the message;
ARGUMENT 'c:\...\...'
I need to change one of the axis produced by persp by giving it labels for the
tickmarks.
The dimension has months (a factor) so the default decimals don't look good.
The graph will finally become a pdf or emf file to be embedded in a document,
so persp3d will not work, I think.
Thank you
Hi,
Today I was flabbergasted to see something that looks like a rounding
error in the very basic seq function in R.
a = seq(0.1,0.9,by=0.1)
a
[1] 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9
a[1] == 0.1
[1] TRUE
a[2] == 0.2
[1] TRUE
a[3] == 0.3
[1] FALSE
It turns out that the alternative
a =

hum,
can you explain that a little more detailed?
Perhaps I miss the background knowledge - but it seems just absurd to
me.
0.1+0.1+0.1 is 0.3 - there is no rounding involved, is there?
why is
x - 0.1 + 0.1 +0.1
not equal to
y - 0.3
?

Remember that this is in BINARY
An extremely verbose, but (in my view) easy to understand approach is:
data.f - data; data.f[which(data = 10)] - levs[1]; data.f[which(data
10)] - levs[2]; data.f - factor(data.f)
